FASTENER IDENTIFICATION
DESCRIPTION
The SAE bolt strength grades range from grade 2 to grade 8. The higher the grade number, the greater the bolt strength. Identification is determined by the line marks on the top of each bolt head. The actual bolt strength grade corresponds to the number of line marks plus 2. The most commonly used metric bolt strength classes are 9.8 and 10.9. The metric strength class identification number is imprinted on the head of the bolt. The higher the class number, the greater the bolt strength. Some metric nuts are imprinted with a single-digit strength class on the nut face. Refer to the Fastener Identification and Fastener Strength Charts (Fig. 3) and (Fig. 4).

SAE VISCOSITY
An SAE viscosity grade is used to specify the vis­cosity of engine oil. Use only engine oils with multi­ple viscosities such as 5W-30 or 10W-30. These are specified with a dual SAE viscosity grade which indi­cates the cold-to-hot temperature viscosity range. Select an engine oil that is best suited to your par­ticular temperature range and variation (Fig. 2).
SAE 5W-30 engine oil is preferred. SAE 5W-30 engine oils improve low temperature starting and helps vehicle fuel economy.
Fig. 2 TEMPERATURE/ENGINE OIL VISCOSITY
ENERGY CONSERVING OIL
An Energy Conserving type oil is recommended for gasoline engines. The designation of ENERGY CON­SERVING is located on the label of an engine oil con­tainer.
SYNTHETIC ENGINE OILS
There are a number of engine oils being promoted as either synthetic or semi-synthetic. If you chose to use such a product, use only those oils that meet the American Petroleum Institute (API) and SAE viscos­ity standard. Follow the service schedule that describes your driving type.
MATERIALS ADDED TO ENGINE OIL
The manufacturer does not recommend the addi­tion of any additive to the specified engine oil.
GEAR LUBRICANTS
SAE ratings also apply to multigrade gear lubri­cants. In addition, API classification defines the lubricants usage. Such as API GL-5 and SAE 75W-
90.
LUBRICANTS AND GREASES
Lubricating grease is rated for quality and usage by the NLGI. All approved products have the NLGI symbol (Fig. 4) on the label. At the bottom NLGI symbol is the usage and quality identification letters. Wheel bearing lubricant is identified by the letter “G”. Chassis lubricant is identified by the latter “L”. The letter following the usage letter indicates the quality of the lubricant. The following symbols indi­cate the highest quality.
CONTAINER IDENTIFICATION
Standard engine oil identification notations have been adopted to aid in the proper selection of engine oil. The identifying notations are located on the front label of engine oil plastic bottles and the top of engine oil cans (Fig. 3).
This symbol means that the oil has been certified by the American Petroleum Institute (API). Diamler­Chrysler only recommends API Certified (GF-3) engine oils that meet the requirements of Material Standard MS-6395. Use Mopar or an equivalent oil meeting the specification MS-6395.

DESCRIPTION - ENGINE COOLANT
WARNING: ANTIFREEZE IS AN ETHYLENE GLYCOL BASE COOLANT AND IS HARMFUL IF SWAL­LOWED OR INHALED. IF SWALLOWED, DRINK TWO GLASSES OF WATER AND INDUCE VOMIT­ING. IF INHALED, MOVE TO FRESH AIR AREA. SEEK MEDICAL ATTENTION IMMEDIATELY. DO NOT STORE IN OPEN OR UNMARKED CONTAINERS. WASH SKIN AND CLOTHING THOROUGHLY AFTER COMING IN CONTACT WITH ETHYLENE GLYCOL. KEEP OUT OF REACH OF CHILDREN. DISPOSE OF GLYCOL BASE COOLANT PROPERLY, CONTACT YOUR DEALER OR GOVERNMENT AGENCY FOR LOCATION OF COLLECTION CENTER IN YOUR AREA. DO NOT OPEN A COOLING SYSTEM WHEN THE ENGINE IS AT OPERATING TEMPERATURE OR HOT UNDER PRESSURE, PERSONAL INJURY CAN RESULT. AVOID RADIATOR COOLING FAN WHEN ENGINE COMPARTMENT RELATED SERVICE IS PERFORMED, PERSONAL INJURY CAN RESULT.
CAUTION: Use of Propylene Glycol based coolants is not recommended, as they provide less freeze protection and less boiling protection.
The cooling system is designed around the coolant. The coolant must accept heat from engine metal, in the cylinder head area near the exhaust valves and engine block. Then coolant carries the heat to the radiator where the tube/fin radiator can transfer the heat to the air.
The use of aluminum cylinder blocks, cylinder heads, and water pumps requires special corrosion protection. Mopart Antifreeze/Coolant, 5 Year/100,000 Mile Formula (MS-9769), or the equiva­lent ethylene glycol base coolant with hybrid organic corrosion inhibitors (called HOAT, for Hybrid Organic Additive Technology) is recommended. This coolant offers the best engine cooling without corrosion when mixed with 50% Ethylene Glycol and 50% distilled water to obtain a freeze point of -37°C (-35°F). If it loses color or becomes contaminated, drain, flush, and replace with fresh properly mixed coolant solu­tion.
The green coolant MUST NOT BE MIXED with the orange or magenta coolants. When replacing cool­ant the complete system flush must be performed before using the replacement coolant.
emergency, it should be replaced with the specified coolant as soon as possible.
DESCRIPTION - TRANSMISSION FLUID
NOTE: Refer to the maintenance schedules in the Owner’s Manual for the recommended maintenance (fluid/filter change) intervals for this transaxle.
NOTE: All transaxles have a common transmission and differential sump. Filling the transaxle accom­modates the differential as well.
TRANSMISSION FLUID
Mopart ATF+4 (Automatic Transmission Fluid­Type 9602) is required in the 41TE automatic. Sub­stitute fluids can induce torque converter clutch shudder.
Mopart ATF+4 (Automatic Transmission Fluid­Type 9602) when new is red in color. The ATF is dyed red so it can be identified from other fluids used in the vehicle such as engine oil or antifreeze. The red color is not permanent and is not an indicator of fluid condition. As the vehicle is driven, the ATF will begin to look darker in color and may eventually become brown. This is normal. A dark brown/black fluid accompanied with a burnt odor and/or deterioration in shift quality may indicate fluid deterioration or transmission component failure.
G288 and T350 Manual transaxles require the use of Mopart ATF+4 (Automatic Transmission Fluid)
FLUID ADDITIVES
DaimlerChrysler strongly recommends against the addition of any fluids to the transmission, other than those automatic transmission fluids listed above. Exceptions to this policy are the use of special dyes to aid in detecting fluid leaks.
Various “special” additives and supplements exist that claim to improve shift feel and/or quality. These additives and others also claim to improve converter clutch operation and inhibit overheating, oxidation, varnish, and sludge. These claims have not been sup­ported to the satisfaction of DaimlerChrysler and these additives must not be used. The use of trans­mission “sealers” should also be avoided, since they may adversely affect the integrity of transmission seals.
CAUTION: MoparT Antifreeze/Coolant, 5 Year/100,000 Mile Formula (MS-9769) may not be mixed with any other type of antifreeze. Doing so will reduce the corrosion protection and may result in premature water pump seal failure. If non-HOAT coolant is introduced into the cooling system in an
DESCRIPTION - FUEL REQUIREMENTS
Your engine is designed to meet all emissions reg­ulations and provide excellent fuel economy and per­formance when using high quality unleaded gasoline having an octane rating of 87. The use of premium gasoline is not recommended. The use of premium
Page 16

FLUID TYPES (Continued)
gasoline will provide no benefit over high quality reg­ular gasoline, and in some circumstances may result in poorer performance.
Light spark knock at low engine speeds is not harmful to your engine. However, continued heavy spark knock at high speeds can cause damage and immediate service is required. Engine damage result­ing from operation with a heavy spark knock may not be covered by the new vehicle warranty.
Poor quality gasoline can cause problems such as hard starting, stalling and hesitations. If you experi­ence these symptoms, try another brand of gasoline before considering service for the vehicle.
Over 40 auto manufacturers world-wide have issued and endorsed consistent gasoline specifications (the Worldwide Fuel Charter, WWFC) to define fuel properties necessary to deliver enhanced emissions, performance and durability for your vehicle. We rec­ommend the use of gasolines that meet the WWFC specifications if they are available.
REFORMULATED GASOLINE
Many areas of the country require the use of cleaner burning gasoline referred to as “reformulat­ed” gasoline. Reformulated gasoline contain oxygen­ates, and are specifically blended to reduce vehicle emissions and improve air quality.
We strongly support the use of reformulated gaso­line. Properly blended reformulated gasoline will pro­vide excellent performance and durability for the engine and fuel system components.
GASOLINE/OXYGENATE BLENDS
Some fuel suppliers blend unleaded gasoline with oxygenates such as 10% ethanol, MTBE, and ETBE. Oxygenates are required in some areas of the country during the winter months to reduce carbon monoxide emissions. Fuels blended with these oxygenates may be used in your vehicle.
line retailer whether or not his/her gasoline contains MMT.
It is even more important to look for gasoline with­out MMT in Canada because MMT can be used at levels higher than allowed in the United States. MMT is prohibited in Federal and California refor­mulated gasoline.
SULFUR IN GASOLINE
If you live in the northeast United States, your vehicle may have been designed to meet California low emission standards with Cleaner-Burning Cali­fornia reformulated gasoline with low sulfur. If such fuels are not available in states adopting California emission standards, your vehicles will operate satis­factorily on fuels meeting federal specifications, but emission control system performance may be adversely affected. Gasoline sold outside of California is permitted to have higher sulfur levels which may affect the performance of the vehicle’s catalytic con­verter. This may cause the Malfunction Indicator Lamp (MIL), Check Engine or Service Engine Soon light to illuminate. We recommend that you try a dif­ferent brand of unleaded gasoline having lower sulfur to determine if the problem is fuel related prior to returning your vehicle to an authorized dealer for service.
CAUTION: If the Malfunction Indicator Lamp (MIL), Check Engine or Service Engine Soon light is flash­ing, immediate service is required; see on-board diagnostics system section.
MATERIALS ADDED TO FUEL
All gasoline sold in the United States and Canada are required to contain effective detergent additives. Use of additional detergents or other additives is not needed under normal conditions.
CAUTION: DO NOT use gasoline containing METH­ANOL. Gasoline containing methanol may damage critical fuel system components.
MMT IN GASOLINE
MMT is a manganese-containing metallic additive that is blended into some gasoline to increase octane. Gasoline blended with MMT provide no performance advantage beyond gasoline of the same octane num­ber without MMT. Gasoline blended with MMT reduce spark plug life and reduce emission system performance in some vehicles. We recommend that gasoline free of MMT be used in your vehicle. The MMT content of gasoline may not be indicated on the gasoline pump; therefore, you should ask your gaso-
FUEL SYSTEM CAUTIONS
CAUTION: Follow these guidelines to maintain your vehicle’s performance:
The use of leaded gas is prohibited by Federal law. Using leaded gasoline can impair engine perfor­mance, damage the emission control system, and could result in loss of warranty coverage.
An out-of-tune engine, or certain fuel or ignition malfunctions, can cause the catalytic converter to overheat. If you notice a pungent burning odor or some light smoke, your engine may be out of tune or malfunctioning and may require immediate service. Contact your dealer for service assistance.
When pulling a heavy load or driving a fully loaded vehicle when the humidity is low and the tem-

perature is high, use a premium unleaded fuel to help prevent spark knock. If spark knock persists, lighten the load, or engine piston damage may result.
The use of fuel additives which are now being sold as octane enhancers is not recommended. Most of these products contain high concentrations of methanol. Fuel system damage or vehicle perfor­mance problems resulting from the use of such fuels or additives is not the responsibility of DaimlerChrysler Corporation and may not be covered under the new vehicle warranty.
NOTE: Intentional tampering with emissions control systems can result in civil penalties being assessed against you.

FRONT SUSPENSION
DESCRIPTION - FRONT SUSPENSION
This vehicle has a gas pressurized MacPherson
strut type front suspension design (Fig. 1).
The front suspension consists of these major com-
ponents:
Hub (pressed into bearing)
Bearing (pressed into steering knuckle)
Lower control arm (2)
Stabilizer bar
Steering knuckle (2)
Strut assembly (2)
Refer to individual components for additional infor-
mation.
OPERATION - FRONT SUSPENSION
The front suspension allows each front wheel on a vehicle to adapt to different road surfaces and condi­tions without greatly affecting the opposite wheel and the ability to control the vehicle. Each side of the front suspension is allowed to pivot so the vehicle can be steered in the direction preferred.
When a vehicle strikes a bump, the force is trans­ferred through the hub, bearing, and knuckle, into the strut assembly to absorb the force and dampen it. During steering maneuvers, the strut assembly (through a pivot bearing in the upper strut mount) and steering knuckle (through the lower ball joint mounted on the lower control arm) turn as an assem­bly.
WARNING
WARNINGS AND CAUTIONS
WARNING: DUST AND DIRT ACCUMULATING ON BRAKE PARTS DURING NORMAL USE MAY CON­TAIN ASBESTOS FIBERS FROM PRODUCTION OR AFTERMARKET LININGS. BREATHING EXCESSIVE CONCENTRATIONS OF ASBESTOS FIBERS CAN CAUSE SERIOUS BODILY HARM. EXERCISE CARE WHEN SERVICING BRAKE PARTS. DO NOT SAND, OR GRIND BRAKE LINING UNLESS EQUIPMENT USED IS DESIGNED TO CONTAIN THE DUST RESI­DUE. DO NOT CLEAN BRAKE PARTS WITH COM­PRESSED AIR OR BY DRY BRUSHING. CLEANING SHOULD BE DONE BY DAMPENING THE BRAKE COMPONENTS WITH A FINE MIST OF WATER, THEN WIPING THE BRAKE COMPONENTS CLEAN WITH A DAMPENED CLOTH. DISPOSE OF CLOTH AND ALL RESIDUE CONTAINING ASBESTOS FIBERS IN AN IMPERMEABLE CONTAINER WITH THE APPROPRIATE LABEL. FOLLOW PRACTICES PRESCRIBED BY THE OCCUPATIONAL SAFETY
AND HEALTH ADMINISTRATION (OSHA) AND THE ENVIRONMENTAL PROTECTION AGENCY (EPA) FOR THE HANDLING, PROCESSING, AND DISPOSI­TION OF DUST OR DEBRIS THAT MAY CONTAIN ASBESTOS FIBERS.
WARNING: DO NOT REMOVE THE STRUT SHAFT NUT WHILE STRUT ASSEMBLY IS INSTALLED IN VEHICLE, OR BEFORE THE COIL SPRING IS COM­PRESSED WITH A COMPRESSION TOOL. THE SPRING IS HELD UNDER HIGH PRESSURE.
CAUTION: Only frame contact hoisting equipment can be used on this vehicle. It cannot be hoisted using equipment designed to lift a vehicle by the rear axle. If this type of hoisting equipment is used, damage to rear suspension components will occur.
CAUTION: At no time when servicing a vehicle can a sheet metal screw, bolt, or other metal fastener be installed in the shock tower to take the place of an original plastic clip. It may come into contact with the strut or coil spring.
CAUTION: Wheel bearing damage will result if after loosening the hub nut, the vehicle is rolled on the ground or the weight of the vehicle is allowed to be supported by the tires for a length of time.
STANDARD PROCEDURE - LUBRICATION
There are no serviceable lubrication points on the front suspension. The front lower ball joints have grease fittings which have had the head snapped off by the manufacturer after they have been filled. This has been done to eliminate the possibility of damag­ing the non-vented seals. Grease will not leak from the broken grease fittings. The ball joints are sealed for life and require no maintenance.
CAUTION: No attempt should be made to replace the ball joint grease fitting with a new fitting, then filling the ball joint with grease. Damage to the grease seal can result.

HUB / BEARING
DESCRIPTION
The wheel bearing and hub are pressed into the steering knuckle. (Refer to 2 - SUSPENSION/ FRONT/KNUCKLE - DESCRIPTION)
OPERATION
The wheel bearing and hub are pressed into the steering knuckle. (Refer to 2 - SUSPENSION/ FRONT/KNUCKLE - OPERATION)
DIAGNOSIS AND TESTING - WHEEL BEARING AND HUB
The wheel bearing is designed for the life of the vehicle and requires no type of periodic maintenance. The following procedure may be used for diagnosing the condition of the wheel bearing and hub.
With the wheel, disc brake caliper, and brake rotor removed, rotate the wheel hub. Any roughness or resistance to rotation may indicate dirt intrusion or a failed hub bearing. If the bearing exhibits any of these conditions during diagnosis, the hub bearing will require replacement. Do not attempt to disas­semble the bearing for repair. If the wheel bearing is disassembled for any reason, it must be replaced.
Damaged bearing seals and the resulting excessive grease loss may also require bearing replacement. Moderate grease weapage from the bearing is consid­ered normal and should not require replacement of the wheel bearing.
To diagnose a bent hub, (Refer to 5 - BRAKES/HY­DRAULIC/MECHANICAL/ROTORS - DIAGNOSIS AND TESTING) for the procedure on measuring hub runout.
REMOVAL
The wheel bearing and hub are pressed into the knuckle. (Refer to 2 - SUSPENSION/FRONT/ KNUCKLE - REMOVAL)
INSTALLATION
The wheel bearing and hub are pressed into the knuckle. (Refer to 2 - SUSPENSION/FRONT/ KNUCKLE - INSTALLATION)
KNUCKLE
DESCRIPTION - STEERING KNUCKLE
The steering knuckle is a single casting with legs machined for attachment to the front strut assembly on the top, lower control arm ball joint on the bot­tom, and steering linkage on the trailing end (Fig. 1). The steering knuckle also has two machined, drilled
and tapped legs on the leading end casting to support and align the front disc brake caliper adapter.
The knuckle supports the wheel bearing and hub (Fig. 1). The wheel hub is pressed into a sealed-for­life wheel bearing that is pressed into the steering knuckle. A retainer plate also holds the bearing in place. The hub supports the driveshaft outer constant velocity (C/V) joint. Each is splined and meshes in the center of the hub. The outer C/V joint is retained to the hub using a nut. The nut is locked to the outer C/V stub shaft using a nut retainer and cotter pin.
The wheel bearing is a Unit 1 type cartridge bear­ing that requires no maintenance. The wheel bearing can be serviced separately from the hub.
The hub has five studs pressed into its flange.
OPERATION - STEERING KNUCKLE
The steering knuckle pivots with the strut assem­bly between the lower ball joint and the pivot bearing in the strut assembly. The steering gear outer tie rod end connects to the trailing end of each knuckle, allowing the vehicle to be steered.
The center of the knuckle supports the hub, wheel bearing and axle shaft.
The hub and wheel bearing work together. The wheel bearing has internal bearings that allow the hub to rotate with the driveshaft and the tire and wheel assembly. The hub’s five studs mount the tire and wheel to the vehicle.
DIAGNOSIS AND TESTING - STEERING KNUCKLE
The front suspension steering knuckle is not a repairable component of the front suspension. It must be replaced if found to be damaged in any way. If it is determined that the steering knuckle is bent when servicing the vehicle, no attempt is to be made to straighten the steering knuckle.
REMOVAL - STEERING KNUCKLE
NOTE: Before proceeding, review all Warnings and Cautions. (Refer to 2 - SUSPENSION/FRONT ­WARNING)

LOWER CONTROL ARM
DESCRIPTION
There is one lower control arm on each side of the vehicle. Each lower control arm is a stamped steel unit using rubber isolated pivot bushings to isolate it from the front suspension crossmember and frame of the vehicle (Fig. 1) . The rear bushing can be ser­viced separately.
The front of the lower control arm is bolted to the front crossmember using a bolt through the center of the rubber pivot bushing. The rear of the lower con­trol arm is mounted to both the front crossmember and the frame rail of the vehicle using a thru-bolt. The thru-bolt goes through both the crossmember and rear lower control arm bushing, threading directly into a caged nut in the frame rail of the vehi­cle.
The left and right lower control arms are intercon­nected through a linked rubber isolated stabilizer bar.
The outboard end of each lower control arm con­nects to the steering knuckle using a ball joint.
The lower control arm connects to the steering knuckle through a ball joint mounted at the outboard end of the arm (Fig. 1) . The ball joint is pressed into the lower control arm and has a non-tapered stud with a notch for steering knuckle pinch bolt clear­ance. The ball joint stud is clamped and locked to the steering knuckle lower leg using a pinch bolt.
The ball joint is lubricated for life during the man­ufacturing process. Once lubricated for life, the grease fitting head is snapped off by the manufac­turer. This is done to eliminate the possibility of lubrication later in the ball joints life thus damaging the non-vented ball joint seal boot.
The ball joint used on this vehicle is replaceable and can be serviced as a separate component of the lower control arm.
OPERATION
The lower control arm supports the lower end of the steering knuckle and allows for the up and down movement of the suspension during the jounce and rebound travel. The lower control arm ball joint con­nects the arm to the steering knuckle.
The ball joint is a pivotal joint on the lower control arm that allows the knuckle to move up and down, and turn with ease.
DIAGNOSIS AND TESTING - LOWER CONTROL ARM
Inspect the lower control arm for signs of damage from contact with the ground or road debris. If the lower control arm shows any sign of damage, look for distortion. Do not attempt to repair or straighten a broken or bent lower control arm. If damaged, the lower control arm stamping is serviced only as a complete component.
The serviceable components of the lower control arm are: the ball joint, the ball joint grease seal and the lower control arm rear isolator bushing.
Inspect both lower control arm isolator bushings for severe deterioration and replace as required. Inspect the ball joint per the inspection procedure in this section of the service manual and replace as required. (Refer to 2 - SUSPENSION/FRONT/ LOWER BALL JOINT - DIAGNOSIS AND TEST­ING).
REMOVAL - LOWER CONTROL ARM
NOTE: Before proceeding, (Refer to 2 - SUSPEN­SION/FRONT - WARNING).
(1) Raise the vehicle. (Refer to LUBRICATION & MAINTENANCE/HOISTING - STANDARD PROCE­DURE)
(2) Remove the front tire and wheel assembly.
(3) Remove both stabilizer bar links from the vehi­cle (Fig. 21). Remove each link by holding the upper retainer/nut with a wrench and turning the link bolt.
(4) Rotate the forward ends of the stabilizer bar downward. It may be necessary to loosen the stabi­lizer bar cushion retainer bolts a little to ease any turning resistance.
(5) Remove the nut and pinch bolt clamping the ball joint stud to the steering knuckle (Fig. 22).
CAUTION: After removing the steering knuckle from the ball joint stud, do not pull outward on the knuckle. Pulling the steering knuckle outward at this point can separate the inner C/V joint on the driveshaft. Refer to FRONT DRIVESHAFTS in the DIFFERENTIAL AND DRIVELINE group for further information.

(3) Clean the threads of the stabilizer bar link bolts, then apply Mopart Lock And Seal or equiva­lent to the threads.
(4) Install both stabilizer bar links back on vehicle (Fig. 35). Start each stabilizer bar link bolt with bushing from the bottom, through the stabilizer bar, inner link bushings, lower control arm, and into the upper retainer/nut and bushing (Fig. 1). Do not fully tighten the link assemblies at this time.
(5) Lower the vehicle.
NOTE: It may be necessary to put the vehicle on a platform hoist or alignment rack to gain access to the stabilizer bar mounting bolts with the vehicle at curb height.
(6) Tighten each stabilizer bar link by holding the upper retainer/nut with a wrench and turning the link bolt. Tighten each link bolt to a torque of 28 N·m (250 in. lbs.).
(7) Tighten the stabilizer bar cushion retainer bolts to a torque of 28 N·m (250 in. lbs.).
STRUT ASSEMBLY
DESCRIPTION
A Macpherson type design strut assembly is used in place of the front suspension upper control arm and upper ball joint (Fig. 1). The bottom of the strut mounts directly to the steering knuckle using 2 attaching bolts and nuts going through the strut cle­vis bracket and steering knuckle. The top of the strut mounts directly to the strut tower of the vehicle using the three threaded studs on the strut assem­blies upper mount.
The strut assembly includes the following compo­nents (Fig. 1):
Upper mount (rubber isolated)
Upper spring seat and bearing
Dust shield
Jounce bumper
Coil spring
Lower spring isolator
Strut (damper)
Each component is serviced by removing the strut assembly from the vehicle and disassembling it.
Coil springs are rated separately for each corner or side of the vehicle depending on optional equipment and type of vehicle service. If a coil spring requires replacement, be sure that it is replaced with a spring meeting the correct load rating for the vehicle and its specific options.
OPERATION
The strut assembly cushions the ride of the vehicle, controlling vibration, jounce and rebound of the sus­pension.
The coil spring controls ride quality and maintains proper ride height.
The spring isolators isolate the coil spring at the top and bottom from coming into metal-to-metal con­tact with the upper mounting seat and the strut.
The jounce bumper limits suspension travel and metal-to-metal contact under full jounce condition.
The strut dampens jounce and rebound motions of the coil spring and suspension.
DIAGNOSIS AND TESTING - STRUT ASSEMBLY (FRONT)
Inspect the strut assembly for the following condi­tions (Fig. 38):
Inspect for a damaged or broken coil spring.
Inspect for a torn or damaged strut assembly
dust shield.
Lift the dust shield and inspect the strut assem­bly for evidence of fluid running from the upper end of the strut fluid reservoir. (Actual leakage will be a stream of fluid running down the side and dripping off lower end of unit). A slight amount of seepage between the strut shaft and strut shaft seal is not unusual and does not affect performance of the strut assembly.
Lift the dust shield and inspect the jounce bumper for signs of damage or deterioration.
Inspect the clearance between the shock tower and the coil spring. Make sure no fasteners are pro­truding through the shock tower possibly contacting the coil spring and strut. Because of the minimum clearance in this area (Fig. 37), installation of metal fasteners could damage the coil spring coating and lead to a corrosion failure of the spring.
CAUTION: At no time when servicing a vehicle can a sheet metal screw, bolt or other metal fastener be installed into the shock tower to take the place of an original plastic clip. Also, do not drill holes into the front shock tower for the installation of any metal fasteners into the shock tower area indicated (Fig. 37).
REMOVAL
NOTE: Before proceeding, (Refer to 2 - SUSPEN­SION/FRONT - WARNING).
(1) Raise the vehicle. (Refer to LUBRICATION & MAINTENANCE/HOISTING - STANDARD PROCE­DURE)

AXLE - FRONT WHEEL DRIVE REAR
DESCRIPTION
The steel rear axle on this vehicle is a twist beam design (Fig. 1) . It has a tubular torsion tube running through the center of its width. It also has two trail­ing arms, one extending from each end of the axle forward. Each trailing arm has a rubber pivot bush­ing pressed into it. Two coil spring perches are mounted to its top surface in line with the rear wheel center.
OPERATION
The rear axle pivots at the forward end of the trail­ing arms through the bushings. Coil springs mounted on top of the axle support the trailing end. As the rear wheels attached to each end of the axle (through spindles) move over bumps and dips, the axle moves with the wheels, pivoting at the front while exerting varying force against the coil springs.
The torsion tube running through the center of the axle’s width acts as an integral tubular stabilizer bar. Jounce and rebound movements affecting one rear wheel are partially transferred to the opposite wheel to help stabilize body roll.
REMOVAL
NEGATIVE CABLE. ALLOW THE SYSTEM CAPACI­TOR TO DISCHARGE FOR TWO (2) MINUTES. FAIL­URE TO DO THIS COULD RESULT IN ACCIDENTAL AIRBAG DEPLOYMENT AND POSSIBLE PERSONAL INJURY.
NOTE: Before proceeding, (Refer to 2 - SUSPEN­SION/REAR - WARNING).
(1) Unclip the air cleaner cover (two clips) and
move the cover aside.
(2) Disconnect and isolate the battery negative
cable from its post on the battery.
(3) Block the tire and wheels so the vehicle does not move once the vehicle parking brake lever is released.
(4) Remove the transmission shift knob as neces­sary.
(5) Remove the screws attaching the center con­sole, then remove the center console.
(6) Grasp the parking brake lever output cable by hand and pull upward. Continue pulling on the cable until an appropriate sized pin punch (drill bit or lock­ing pin) can be inserted sufficiently through the hole in the left side of the lever mounting bracket (Fig. 3). This will lock the parking brake automatic adjust­ment mechanism in place and take tension off the parking brake cables. Slowly release the output cable. There should now be slack in the cables.
WARNING: THE AUTOMATIC ADJUSTING FEATURE OF THIS PARKING BRAKE LEVER CONTAINS A CLOCKSPRING LOADED TO APPROXIMATELY 19 POUNDS. DO NOT RELEASE THE AUTOMATIC ADJUSTER LOCKOUT DEVICE UNLESS THE REAR PARKING BRAKE CABLES AND EQUALIZER ARE CONNECTED TO THE LEVER OUTPUT CABLE. KEEP HANDS OUT OF AUTOMATIC ADJUSTER SECTOR AND PAWL AREA. FAILURE TO OBSERVE CAUTION IN HANDLING THIS MECHANISM COULD LEAD TO SERIOUS INJURY.
WARNING: WHEN REPAIRS TO THE PARKING BRAKE LEVER OR CABLES ARE REQUIRED, THE AUTOMATIC ADJUSTER MUST BE LOADED AND LOCKED OUT TO AVOID POSSIBLE INJURY. THE LEVER ADJUSTMENT MECHANISM CAN BE LOADED AND LOCKED OUT AS OUTLINED IN THIS PROCEDURE.

HUB / BEARING
DESCRIPTION
The rear wheel bearing and wheel mounting hub used on this vehicle are a one-piece sealed unit or hub and bearing assembly. It is permanently lubri­cated when assembled and is sealed for life. There is no periodic lubrication or maintenance recommended for these units.
The hub and bearing is mounted on the spindle which is bolted to the axle (Fig. 23). The hub and bearing is secured to the spindle using a special nut.
Vehicles equipped with antilock brakes have rear hub and bearings with the tone wheel for the rear wheel speed sensors pressed onto the hub.
The only serviceable components of the hub and bearing are the wheel mounting studs pressed into the hub.
OPERATION
The hub and bearing adapts the tire and wheel assembly to the axle mounted spindle. It’s bearing allows the tire and wheel assembly to rotate freely on the vehicle. The brake drum or brake rotor mounts to the hub’s wheel mounting studs aiding in stopping the vehicle when required.
On vehicles equipped with antilock brakes, the tone wheel pressed onto the hub allows the brake system to sense wheel motion.
DIAGNOSIS AND TESTING - HUB AND BEARING (REAR)
The hub and bearing is designed for the life of the vehicle and requires no type of periodic maintenance. The following procedure may be used for diagnosing the condition of the hub and bearing.
With the wheel, disc brake rotor or brake drum removed, rotate the hub. Any roughness or resistance to rotation may indicate dirt intrusion or a failed hub bearing. If the bearing exhibits any of these condi­tions during diagnosis, the hub and bearing will require replacement. The bearing is not serviceable alone.
Damaged bearing seals and the resulting excessive grease loss may also require hub and bearing replacement. Moderate grease weapage from the bearing is considered normal and should not require replacement of the wheel bearing.
To diagnose a bent hub, refer to ROTOR in BRAKES for the procedure on measuring hub runout.

(3) The coil springs require proper orientation to the body when installed. To do this, turn the coil springs (along with the rubber isolators) until the flat end of each upper spring coil lines up with an imaginary line running parallel with the axle beam as shown (Fig. 33). Also, make sure that the upper coils end near the outboard sides of the vehicle and not 180 degrees of that location.
(4) Raise the transmission jack guiding the coil springs into the spring mounting brackets on the body of the vehicle. Raise the jack until the shock absorber lower mounting bolts can be installed though the axle brackets and shock absorber lower mounting eyes (Fig. 30).
(5) Install the washer and nut on the end of each shock absorber lower mounting bolt. Tighten the mounting bolts to a torque of 88 N·m (65 ft. lbs.).
(6) Remove the jack.
(7) If equipped with a rear stabilizer bar, hook the lower ends of the stabilizer bar cushion retainers into the slots in the back of the axle, then rotate the opposite end of the retainers upward so the mounting bolts can be installed. Install the mounting bolt though each cushion retainer into the threads in the rear axle (Fig. 31). Tighten the rear stabilizer bar cushion retainer bolts to a torque of 61 N·m (45 ft. lbs.).
(2) Place the coil springs on top of the axle spring
perches.
CAUTION: When installing the watts links and bell crank to the axle, make sure the bell crank is right­side-up. When mounted properly, the words “BACK UP” should be able to be read from the rear over the top of the axle (Fig. 34).

WATTS LINK ASSEMBLY
DESCRIPTION
The watts link assembly consists of a bell crank mounted to the rear axle and two links extending from the bell crank to brackets mounted to the body of the vehicle (Fig. 37).
The cast iron bell crank has a non—serviceable sealed—for—life bearing mounted in the center of it through which it is fastened to the axle. It also has the words “BACK UP” cast into one side of it indicat­ing the installation direction when mounted to the axle (Fig. 36). Although the pivot may look identical end to end, it is not and must be installed with the words “BACK UP” toward the back of the vehicle fac­ing upright in order to avoid premature bearing fail­ure.
REMOVAL
NOTE: Before proceeding, (Refer to 2 - SUSPEN­SION/REAR - WARNING).
(1) Raise the vehicle. (Refer to LUBRICATION & MAINTENANCE/HOISTING - STANDARD PROCE­DURE)
(2) Remove the appropriate rear wheel and tire assembly from the vehicle.
(3) Remove the nut and bolt from the lower end of the stabilizer bar link attaching it to the stabilizer bar (Fig. 35).
(4) Remove the bolt retaining the link to the rear frame rail (Fig. 35), then remove the stabilizer bar link from the vehicle.

(1) Reinstall stabilizer bar link, starting the bolt retaining the link to frame rail (Fig. 35). Do not tighten the bolt at this time.
(2) Install the lower bolt and nut attaching the stabilizer bar link to the stabilizer bar (Fig. 35). Do not tighten the bolt and nut at this time.
(3) Install tire and wheel assembly on the vehicle. Tighten the wheel mounting stud nuts in proper sequence until all nuts are torqued to half specifica­tion. Repeat the tightening sequence, this time, to full specified torque of 135 N·m (100 ft. lbs.).
(4) Lower the vehicle to ground level (curb height).
Fig. 36 Bell Crank
1 - INSTALLATION DIRECTION
The upper and lower links both have ball joints on one end and bushings on the other. The ball joint ends connect to the bell crank and the bushing ends connect to a bracket on the body. The upper link extends from the upper hole machined into the bell crank to the bracket on the right side of the vehicle. The lower link extends from the lower hole machined into the bell crank to the bracket on the left side of the vehicle. Although the links look like outer tie rods, no attempt should be made to adjust them. They are fixed to a set length at the factory and require no maintenance. The bushings on the links are not serviceable.
Page 77
PT REAR SUSPENSION 2 - 49
WATTS LINK ASSEMBLY (Continued)
OPERATION
The watts link assembly serves the same purpose as a track bar. That is, it is used to control rear axle lateral movement and provides cross-car location of the axle. Unlike a track bar, the watts link assembly offers more consistent handling and stability at vary­ing suspension heights, either lightly loaded or fully laden. As the suspension lowers or raises, the watts link assembly compensates by rotating the bell crank in the desired direction. This rotation simulates shortening or lengthening of the links. Since there is one link on each side, the change affects each side of the suspension evenly.
DIAGNOSIS AND TESTING - WATTS LINK ASSEMBLY
Inspect each link looking for signs of contact with an object that has caused damage to the link. If a link is bent or damaged, replace it. Do not attempt to repair or straighten a watts link.
Verify there is not excessive play in the ball joint end of each link. Check to make sure the ball joint boots are not torn. Verify the stakes are tightly securing the ball joint forging to the link. Replace the links as necessary. Do not attempt to remove the ball joint from a link or re-stake it. Although it may appear so, the ball joints cannot be serviced sepa­rately from the watts links.
Inspect the link bushings for signs of damage or deterioration. If damage or deterioration is present, replace the link. The isolator bushings cannot be ser­viced separately.
Verify the bell crank is installed properly. From the rear of the vehicle, the words “BACK UP” should be able to be read on the upper half of the bell crank extending above the axle. If not, remove the bell crank and remount it correctly. If the bell crank is not correctly mounted, the watts link assembly will not operate properly.
Inspect the bell crank for signs of damage. Inspect for excessive play in the bearing. With the links dis­connected, rotate the bell crank. Any roughness or resistance to rotate may indicate dirt intrusion or a failed bearing. If the bell crank exhibits any of these conditions, replace the bell crank.

WHEEL ALIGNMENT
DESCRIPTION - WHEEL ALIGNMENT
Vehicle wheel alignment is the positioning of all interrelated front and rear suspension angles. These angles affect the handling and steering of the vehicle when it is in motion. Proper wheel alignment is essential for efficient steering, good directional stabil­ity, and proper tire wear.
The method of checking a vehicle’s front and rear wheel alignment varies depending on the manufac­turer and type of equipment used. The manufactur­er’s instructions should always be followed to ensure accuracy of the alignment, except when DaimlerChrysler Corporation’s wheel alignment spec­ifications differ.
On this vehicle, the suspension angles that can be adjusted are as follows:
Front
Camber
Toe
Rear
Camber
Toe
Check the wheel alignment and make all wheel alignment adjustments with the vehicle standing at its proper curb height specification. Curb height is the normal riding height of the vehicle. It is mea­sured from a certain point on the vehicle to the ground or a designated area while the vehicle is sit­ting on a flat, level surface. Refer to Curb Height Measurement in this section for additional informa­tion.
Typical wheel alignment angles and measurements are described in the following paragraphs.

sured in degrees of angle relative to a true vertical line. Camber is a tire wearing angle.
Excessive negative camber will cause tread wear
at the inside of the tire.
Excessive positive camber will cause tread wear
on the outside of the tire.
CAMBER
Camber is the inward or outward tilt of the top of the tire and wheel assembly (Fig. 1). Camber is mea-

Page 81
PT WHEEL ALIGNMENT 2 - 53
WHEEL ALIGNMENT (Continued)
CROSS CAMBER
Cross camber is the difference between left and right camber. To achieve the cross camber reading, subtract the right side camber reading from the left. For example, if the left camber is +0.3° and the right camber is 0.0°, the cross camber would be +0.3°.
CASTER
Caster is the forward or rearward tilt of the steer­ing knuckle in reference to the position of the upper and lower ball joints. Caster is measured in degrees of angle relative to a true vertical center line. This line is viewed from the side of the tire and wheel assembly (Fig. 2).
Forward tilt (upper ball joint ahead of lower)
results in a negative caster angle.
Rearward tilt (upper ball joint trailing lower)
results in a positive caster angle.
Although caster does not affect tire wear, a caster imbalance between the two front wheels may cause the vehicle to lead to the side with the least positive caster.
TOE
Toe is the inward or outward angle of the wheels
as viewed from above the vehicle (Fig. 3).
Toe-in is produced when the front edges of the wheels on the same axle are closer together than the rear edges.
Toe-out is produced when the front edges of the wheels on the same axle are farther apart than the rear edges.
Toe-in and toe-out can occur at the front wheels
and the rear wheels.
Toe is measured in degrees or inches. The mea­surement identifies the amount that the front of the wheels point inward (toe-in) or outward (toe-out). Toe is measured at the spindle height. Zero toe means the front and rear edges of the wheels on the same axle are equally distant.
Fig. 2 Caster
CROSS CASTER
Cross caster is the difference between left and
right caster.
Fig. 3 Toe

Page 82
2 - 54 WHEEL ALIGNMENT PT
WHEEL ALIGNMENT (Continued)
TOE-OUT ON TURNS
Toe-out on turns is the relative positioning of the front wheels while steering through a turn (Fig. 4). This compensates for each front wheel’s turning radius. As the vehicle encounters a turn, the out­board wheel must travel in a larger radius circle than the inboard wheel. The steering system is designed to make each wheel follow its particular radius circle. To accomplish this, the front wheels must progressively toe outward as the steering is turned from center. This eliminates tire scrubbing and undue tire wear when steering a vehicle through a turn.
STEERING AXIS INCLINATION (S.A.I.)
Steering axis inclination is the angle between a true vertical line starting at the center of the tire at the road contact point and a line drawn through the center of the upper ball joint (or strut) and the lower ball joint (Fig. 5). S.A.I. is built into the vehicle and is not an adjustable angle. If S.A.I. is not within specifications, a bent or damaged suspension compo­nent may be the cause.
Fig. 4 Toe-Out On Turns
1 - TOE-OUT ON TURNS
DYNAMIC TOE PATTERN
Dynamic toe pattern is the inward and outward toe movement of the front and rear tires through the suspension’s jounce and rebound travel. As the vehi­cle’s suspension moves up and down, the toe pattern varies. Toe pattern is critical in controlling the direc­tional stability of the vehicle while in motion. Front and rear dynamic toe pattern is preset by the factory at the time the vehicle is assembled.
It is not necessary to check or adjust front or rear dynamic toe pattern when doing a normal wheel alignment. The only time dynamic toe pattern needs to be checked or adjusted is if the frame of the vehi­cle has been damaged.
Fig. 5 S.A.I. and I.A.
1 - S.A.I. 2 - CAMBER 3 - I.A.
INCLUDED ANGLE (I.A.)
Included angle is the sum of the S.A.I. angle plus or minus the camber angle, depending on whether or not the wheel has positive or negative camber (Fig.
5). If camber is positive, add the camber angle to the S.A.I angle. If camber is negative, subtract the cam­ber angle from the S.A.I. angle. Included angle is not adjustable, but can be used to diagnose a frame mis­alignment or bent suspension component (spindle, strut).
Page 83
PT WHEEL ALIGNMENT 2 - 55
WHEEL ALIGNMENT (Continued)
THRUST ANGLE
Thrust angle is the averaged direction the rear wheels are pointing in relation to the vehicle’s center line (Fig. 6). The presence of negative or positive thrust angle causes the rear tires to track improperly to the left or right of the front tires (dog tracking).
Negative thrust angle means the rear tires are
tracking to the left of the front tires.
Positive thrust angle means the rear tires are
tracking to the right of the front tires.
Improper tracking can cause undue tire wear, a lead or pull and a crooked steering wheel. Excessive thrust angle can usually be corrected by adjusting the rear wheel toe so that each wheel has one-half of the total toe measurement.

STANDARD PROCEDURE
STANDARD PROCEDURE - CURB HEIGHT MEASUREMENT
The wheel alignment is to be checked and all align­ment adjustments made with the vehicle at its required curb height specification.
Vehicle height is to be checked with the vehicle on a flat, level surface, preferably a vehicle alignment rack. The tires are to be inflated to the recommended pressure. All tires are to be the same size as stan­dard equipment. Vehicle height is checked with the fuel tank full of fuel, and no passenger or luggage compartment load.
Vehicle height is not adjustable. If the measure­ment is not within specifications, inspect the vehicle for bent or weak suspension components. Compare the parts tag on the suspect coil spring(s) to the parts book and the vehicle sales code, checking for a match. Once removed from the vehicle, compare the

coil spring height to a correct new or known good coil spring. The heights should vary if the suspect spring is weak.
NOTE: Prior to reading the curb height measure­ment, the front an rear of the vehicle should be jounced. Induce jounce by grasping the center of the rear, then front bumper (or fascia) and jouncing the vehicle an equal number of times. Release the bumper at the bottom of the jounce cycle.
(1) Measure from the edge of the wheel opening fender lip directly above the wheel center (spindle) down to the floor or alignment rack surface.
(2) When measuring, maximum left-to-right differ­ential is not to exceed 10 mm (0.39 in.).
(3) Compare the measurements to specifications listed in the following CURB HEIGHT SPECIFICA­TIONS chart.

PRE-WHEEL ALIGNMENT INSPECTION
CAUTION: If during the inspection the front suspen­sion crossmember shows any sign of impact dam­age, the steering column lower coupling must be inspected. (Refer to 19 - STEERING/COLUMN/ STEERING COUPLING - DIAGNOSIS AND TESTING)
Before any attempt is made to change or correct the wheel alignment, the following inspection and necessary corrections must be made to the vehicle to ensure proper alignment.
(1) Be sure the fuel tank is full of fuel. If the fuel tank is not full, the reduction in weight will affect the curb height of the vehicle and the alignment specifications.
(2) The passenger and luggage compartments of the vehicle should be free of any load that is not fac­tory equipment.
(3) Check the tires on the vehicle. The tires are to be inflated to the recommended air pressure. All tires must be the same size and in good condition with approximately the same tread wear.
(4) Check the front tire and wheel assemblies for excessive radial runout.
(5) Inspect all suspension component fasteners for looseness and proper torque.
(6) Inspect the lower front ball joints and all steer­ing linkage for looseness and any sign of wear or damage.
(7) Inspect the rubber bushings on all the suspen­sion components for signs of wear or deterioration. If any bushings show signs of wear or deterioration, they should be replaced prior to aligning the vehicle.
(8) Check vehicle curb height to verify it is within specifications. (Refer to 2 - SUSPENSION/WHEEL ALIGNMENT - STANDARD PROCEDURE)
WHEEL ALIGNMENT SETUP
(1) Position the vehicle on an alignment rack.
(2) Install all required alignment equipment on the vehicle, per the alignment equipment manufac­turer’s instructions. On this vehicle, a four-wheel alignment is recommended.
NOTE: Prior to reading the vehicle’s alignment readouts, the front and rear of vehicle should be jounced. Induce jounce (rear first, then front) by grasping the center of the bumper and jouncing each end of vehicle an equal number of times. The bumper should always be released when vehicle is at the bottom of the jounce cycle.
(3) Read the vehicle’s current front and rear align­ment settings. Compare the vehicle’s current align-
ment settings to the vehicle specifications for camber, caster and toe-in. (Refer to 2 - SUSPENSION/ WHEEL ALIGNMENT - SPECIFICATIONS)
REAR CAMBER AND TOE
Rear camber and rear toe settings on this vehicle are determined at the time the vehicle is designed, by the location of the vehicle’s suspension components. This is referred to as Net Build. The result is no required adjustment of camber and toe after the vehi­cle is built or when servicing the suspension compo­nents. Thus, when performing a wheel alignment, rear camber and toe are not normally considered adjust­able angles. Although not normally considered adjust­able, rear camber and toe can be changed when necessary through the use of specially designed shims. To install shims, use the following procedure.
(1) Raise the vehicle until its tires are off the floor or alignment rack.
(2) Remove the tire and wheel assembly.
(3) Access the spindle mounting bolts following the Spindle Removal procedure found in Rear Suspen­sion. (Refer to 2 - SUSPENSION/REAR/SPINDLE ­REMOVAL)
(4) Loosen the four spindle mounting bolts just enough to slide the adjustment shim in between the spindle and the axle mounting flange.
NOTE: Each shim is 0.010 in. (0.254 mm) thick. Do not place more than two shims at any one spindle.
(5) Hook the shim on the mounting bolts utilizing the slots cut into the shim. Refer to the following list for shim placement:
To achieve more positive camber, place the shim
across the two upper mounting bolts.
To achieve more negative camber, place the shim
across the two lower mounting bolts.
To achieve more positive toe, place the shim
across the two rearward mounting bolts.
To achieve more negative toe, place the shim
across the two forward mounting bolts.
(6) Tighten the four mounting bolts to a torque of 95 N·m (70 ft. lbs.).
(7) Reassemble the rear brake following the Spin­dle Installation procedure found in Rear Suspension. (Refer to 2 - SUSPENSION/REAR/SPINDLE ­INSTALLATION)
(8) Reinstall the tire and wheel assembly. Tighten the wheel mounting nuts to a torque of 135 N·m (100 ft. lbs.).
(9) Lower the vehicle.
(10) Once rear camber and toe have been set to specifications, check and adjust the front wheel align­ment as necessary. Refer to FRONT CAMBER AND CASTER and FRONT TOE within this wheel align­ment service procedure.

WHEEL ALIGNMENT (Continued)
FRONT CAMBER AND CASTER
Front camber and caster settings on this vehicle are determined at the time the vehicle is designed, by the location of the vehicle’s suspension compo­nents. This is referred to as Net Build. The result is no required adjustment of camber and caster after the vehicle is built or when servicing the suspension components. Thus, when performing a wheel align­ment, caster and camber are not normally considered adjustable angles. Camber and caster should be checked to ensure they meet vehicle specifications. (Refer to 2 - SUSPENSION/WHEEL ALIGNMENT ­SPECIFICATIONS)
If front camber is found not to meet alignment specifications, it can be adjusted using an available camber adjustment bolt package. Before installing a camber adjustment bolt package on a vehicle found to be outside the specifications, inspect the suspen­sion components for any signs of damage or bending.
No adjustment can be made to the caster setting on this vehicle. If the vehicle’s caster is not within alignment specifications, check for damaged suspen­sion components or body parts.
CAUTION: Do not attempt to adjust the vehicles wheel alignment by heating or bending any of the suspension components.
CAMBER ADJUSTMENT BOLT PACKAGE INSTALLATION
The camber adjustment bolt package contains new bolts and nuts for attaching the strut clevis bracket to the steering knuckle. The bolts contained in the package are slightly undersize allowing for move­ment between the strut clevis bracket and the steer­ing knuckle. The movement allowed by the undersize bolts provide approximately two degrees of camber adjustment per side of the vehicle. To install and adjust the camber adjustment bolt package, follow the procedure below.
(1) Raise the vehicle until its tires are not support­ing the weight of the vehicle.
CAUTION: The knuckle to strut assembly attaching bolt shanks are serrated and must not be turned during removal. Remove the nuts while holding the bolts stationary.
(2) Remove the original upper bolt attaching the strut clevis bracket to the knuckle (Fig. 7).
(3) Install a bolt from the adjustment package into the hole where the original bolt was removed. Install the bolt from the rear.
(4) Install a nut provided in adjustment package on the replacement bolt. Tighten the nut until it’s snug, but still allowing the knuckle to slide in the clevis bracket.

(6) Install a bolt from the adjustment package into the bottom hole of the strut clevis bracket. Install the bolt from the rear.
(7) Install a nut provided in adjustment package on the replacement bolt. Tighten the nut until it’s snug.
(8) Reinstall the tire and wheel assembly. Tighten the wheel mounting nuts to a torque of 135 N·m (100 ft. lbs.)
(9) Perform the above procedure to opposite strut as required.
(10) Lower the vehicle and jounce the front and rear of the vehicle.
(11) Adjust the front camber to the preferred set­ting by pushing or pulling on the top of the tire. When camber is set to specifications, tighten the upper and lower strut clevis bracket bolts. Again jounce the front and rear of the vehicle, then verify the camber settings.
(12) Torque front strut clevis bracket-to-steering knuckle attaching bolts to 53 N·m (40 ft. lbs.), plus an additional 1/4 turn after the torque is met.
(13) Once camber is within specifications, adjust toe to meet the preferred specification setting. Refer to FRONT TOE within this wheel alignment service procedure.

HALF SHAFT
DESCRIPTION
All Models Except Diesel and Turbo
1.6L, 2.0L and 2.4L naturally aspirated models equipped with either an automatic or manual trans­mission use an unequal-length halfshaft system. The system incorporates two halfshaft assemblies (left and right) that consist of an inner and outer constant velocity (CV) joint and a solid interconnecting shaft (Fig. 1). The right halfshaft is longer than the left due to transaxle packaging and powertrain design.

Halfshafts used on both the right and left sides of the vehicle use a tuned rubber damper weight mounted to the interconnecting shaft (Fig. 1). The damper weight applications vary by which side of the vehicle the halfshaft is located on and the transmis­sion application of the vehicle. When replacing a halfshaft, be sure the replacement halfshaft has the same damper weight as the original.

Diesel and Turbo Models
Vehicles equipped with the 2.2L Turbo Diesel and the 2.4L Turbo Gasoline utilize an equal-length half­shaft system. The system incorporates two halfshaft assemblies (left and right) that consist of an inner and outer constant velocity (CV) joint and a solid interconnecting shaft, and an intermediate shaft/ bearing assembly as shown in (Fig. 2)
The left halfshaft uses a tuned-rubber damper weight mounted to the interconnecting shaft (Fig. 2). When replacing a halfshaft, be sure the replacement halfshaft has the same damper weight as the origi­nal.
Both halfshaft assemblies use the same type of inner and outer joints. The inner joint of both half­shaft assemblies is a tripod joint, and the outer joint of both halfshaft assemblies is a Rzeppa joint. Both tripod joints and Rzeppa joints are true constant velocity (C/V) joint assemblies. The inner tripod joint allows for the changes in halfshaft length through the jounce and rebound travel of the front suspen­sion.
On vehicles equipped with ABS brakes, the outer C/V joint is equipped with a tone wheel used to determine vehicle speed for ABS brake operation.
The left halfshaft inner tripod joint and the inter­mediate shaft are both splined into the transaxle side gears. The inner tripod joints are retained using a
snap ring located in the stub shaft of the tripod joint. The outer C/V joint has a stub shaft that is splined into the wheel hub and retained by a hub nut, nut lock, wave washer and cotter pin (Fig. 3).
NOTE: This vehicle does not use a rubber–lip bear­ing seal as on previous front–wheel–drive cars to prevent contamination of the front wheel bearing. On these vehicles, the face of the outer C/V joint fits deeply into the steering knuckle, using a close outer C/V joint–to–steering knuckle fit. This design deters direct water splash on bearing seal while allowing any water that gets in, to run out the bot­tom of the steering knuckle bearing bore. It is important to thoroughly clean the outer C/V joint and the wheel bearing area in the steering knuckle before it is assembled after servicing.
OPERATION
Halfshaft assemblies are designed to transmit power from the transaxle to the front wheels, while allowing for powertrain and suspension flex.

VEHICLE INSPECTION
(1) Check for grease in the vicinity of the inboard
tripod joint and outboard C/V joint; this is a sign of
4 - BOLT (3) 5 - HALFSHAFT (RH)
inner or outer joint seal boot or seal boot clamp dam­age.
NOISE AND/OR VIBRATION IN TURNS
A clicking noise and/or a vibration in turns could be caused by one of the following conditions:
(1) Loose hub nut. Using a click-style torque wrench, torque hub nut to 244 N·m (180 ft. lbs.).
(2) Damaged outer C/V or inner tripod joint seal boot or seal boot clamps, which is evident by the presence of grease slung outward from the joint. This will result in the loss and/or contamination of the joint grease, resulting in inadequate lubrication of the joint.
(3) Noise may also be caused by another compo­nent of the vehicle coming in contact with the half­shafts.
CLUNKING NOISE DURING ACCELERATION
This noise may be a result of one of the following conditions:
(1) A torn seal boot on the inner or outer joint of the halfshaft assembly, which is evident by the pres­ence of grease slung outward from the joint. This will result in the loss and/or contamination of the joint grease, resulting in inadequate lubrication of the joint.
Page 92

REMOVAL
REMOVAL—EXCEPT DIESEL AND TURBO MODELS
CAUTION: Boot sealing is vital to retain special lubricants and to prevent foreign contaminants from entering the C/V joint. Mishandling, such as allowing the assemblies to dangle unsupported, or pulling or pushing the ends can cut boots or dam­age C/V joints. During removal and installation pro­cedures, always support both ends of the halfshaft to prevent damage.
CAUTION: The halfshaft, when installed, acts as a bolt and secures the front hub/bearing assembly. If vehicle is to be supported or moved on its wheels with a halfshaft removed, install a PROPER–SIZED BOLT AND NUT through front hub. Tighten bolt and nut to 244 N·m (180 ft. lbs.). This will ensure that the hub bearing cannot loosen.
(1) Disconnect battery negative cable.
(2) Place transaxle in gated park.
(3) Raise vehicle on hoist.
(4) Remove wheel and tire assembly (Fig. 4).
(5) Remove the cotter pin, nut lock, and spring washer, and hub nut from the end of the outer C/V joint stub axle (Fig. 5).
