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. 2) and (Fig. 3).

DESCRIPTION - ENGINE OIL AND LUBRICANTS
WARNING: NEW OR USED ENGINE OIL CAN BE IRRITATING TO THE SKIN. AVOID PROLONGED OR REPEATED SKIN CONTACT WITH ENGINE OIL. CONTAMINANTS IN USED ENGINE OIL, CAUSED BY INTERNAL COMBUSTION, CAN BE HAZARDOUS TO YOUR HEALTH. THOROUGHLY WASH EXPOSED SKIN WITH SOAP AND WATER. DO NOT WASH SKIN WITH GASOLINE, DIESEL FUEL, THINNER, OR SOLVENTS, HEALTH PROBLEMS CAN RESULT. DO NOT POLLUTE, DISPOSE OF USED ENGINE OIL PROPERLY. CONTACT YOUR DEALER OR GOVERN­MENT AGENCY FOR LOCATION OF COLLECTION CENTER IN YOUR AREA.
When service is required, DaimlerChrysler Corpo­ration recommends that only Mopart brand parts, lubricants and chemicals be used. Mopart provides the best engineered products for servicing DaimlerChrysler Corporation vehicles.
Only lubricants bearing designations defined by the following organization should be used.
Society of Automotive Engineers (SAE)
American Petroleum Institute (API)
National Lubricating Grease Institute (NLGI)

FLUID TYPES (Continued)
API SERVICE GRADE CERTIFIED
Use an engine oil that is API Certified (GF-3). Mopart provides engine oils, meeting Material Stan­dard MS-6395, that meet or exceed this requirement.
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).
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.
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 Mopart or an equivalent oil meeting the specification MS-6395.
ENGINE OIL ADDITIVES/SUPPLEMENTS
The manufacturer does not recommend the addi­tion of any engine oil additives/supplements to the specified engine oil. Engine oil additives/supplements should not be used to enhance engine oil perfor­mance. Engine oil additives/supplements should not be used to extend engine oil change intervals. No additive is known to be safe for engine durability and can degrade emission components. Additives can con­tain undesirable materials that harm the long term durability of engines by:
Doubling the level of Phosphorus in the engine oil. The ILSAC (International Lubricant Standard Approval Committee) GF-2 and GF-3 standards require that engine oil contain no more than 0.10% Phosphorus to protect the vehicles emissions perfor­mance. Addition of engine oil additives/supplements can poison, from the added sulfur and phosphorus, catalysts and hinder efforts to guarantee emissions performance to 80,000 miles.
Altering the viscosity characteristics of the engine oil so that it no longer meets the require­ments of the specified viscosity grade.
Creating potential for an undesirable additive compatibility interaction in the engine crankcase. Generally it is not desirable to mix additive packages from different suppliers in the crankcase; there have been reports of low temperature engine failures caused by additive package incompatibility with such mixtures.
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.
Fig. 3 API SYMBOL
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.
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 of the NLGI symbol is the usage and quality identification letters. Wheel bearing lubricant is identified by the letter “G”. Chassis lubricant is identified by the letter “L”. The letter following the usage letter indicates

SPECIALIZED LUBRICANTS AND OILS
Some maintenance or repair procedures may require the use of specialized lubricants or oils. Con­sult the appropriate sections in this manual for the correct application of these lubricants.
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.
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 emergency, it should be replaced with the specified coolant as soon as possi­ble.
DESCRIPTION - FLEXIBLE FUEL VEHICLES (2.7L ENGINES ONLY)
The information in this section is for Flexible Fuel Vehicles (FFV) only. These vehicles can be identified by the unique Fuel Filler Door Label that states Ethanol (E-85) or Unleaded Gasoline Only. This section only covers those subjects that are unique to these vehicles. Please refer to the other sections of this manual for information on features that are common between Flexible Fuel and gasoline only powered vehicles.
CAUTION: Only vehicles with the E-85 fuel filler door label can operate on E-85.
Ethanol Fuel (E-85)
E-85 is a mixture of approximately 85% fuel etha­nol and 15% unleaded gasoline.
WARNING: Ethanol vapors are extremely flammable and could cause serious personal injury. Never have any smoking materials lit in or near the vehi­cle when removing the fuel filler tube cap (gas cap) or filling the tank. Do not use E-85 as a cleaning agent and never use it near an open flame.
Page 21

FLUID TYPES (Continued)
Fuel Requirements
The vehicle will operate on both unleaded gasoline with an octane rating of 87, or E-85 fuel, or any mix­ture of these two.
For best results, a refueling pattern that alternates between E-85 and unleaded gasoline should be avoided. When you do switch fuels, it is recom­mended that
you do not switch when the fuel gauge indicates
less than 1/4 full
you do not add less than 5 gallons when refuel-
ing
you operate the vehicle immediately after refuel-
ing for a period of at least 5 minutes
Observing these precautions will avoid possible hard starting and/or significant deterioration in driveability during warm up.
NOTE: When the ambient temperature is above 90°F, you may experience hard starting and rough idle following start up even if the above recommen­dations are followed.
Engine Oil Selection for Operating on E-85
If vehicle operates on E-85 fuel either full or part­time, use only Mopart Flexible Fuel 5W-30 engine oil or an equivalent that meets DaimlerChrysler Stan­dard MS-9214. Equivalent commercial Flexible Fuel engine oils may be labeled as Multi-Fuel, Variable Fuel, Flexible Fuel, etc. These engine oils may be satisfactory if they meet the DaimlerChrysler Stan­dard.
SAE 5W-30 engine oil is preferred for use in Flex­ible Fuel engines.
Cruising Range
Because E-85 fuel contains less energy per gallon than gasoline, you will experience an increase in fuel consumption. You can expect your MPG and your driving range to decrease by about 30% compared to gasoline operation.
Replacement Parts
Many components in your Flexible Fuel Vehicle (FFV) are designed to be compatible with ethanol. Always be sure that your vehicle is serviced with cor­rect ethanol compatible parts.
CAUTION: Replacing fuel system components with non-ethanol compatible components can damage your vehicle and may void the warranty.
Maintenance
If you operate the vehicle using E-85 fuel, follow Schedule B in the maintenance schedule section of this manual.
DESCRIPTION - AUTOMATIC/MANUAL TRANSAXLE FLUID
NOTE: Refer to the maintenance schedules in the vehicle 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.
CAUTION: If Flexible Fuel engine oil is not used when using E-85 fuel, engine wear or damage may result.
Engine Oil Selection for Operating on Gasoline
If you operate the vehicle on regular unleaded gas­oline ONLY, use Mopart oil or an equivalent that meets certified API (American Petroleum Institute) Quality.
Starting
The characteristics of E-85 fuel make it unsuitable for use when ambient temperatures fall below 0°F. In the range of 0°F to 32°F, you may experience an increase in the time it takes for your engine to start, and a deterioration in driveability (sags and/or hesi­tations) until the engine is fully warmed up.
TRANSMISSION FLUID
Mopart ATF+4 (Automatic Transmission Fluid) is required in the 41TE automatic and T350/T850 man­ual transaxles. Substitute fluids can induce torque converter clutch shudder, or premature geartrain failure.
Mopart ATF+4 (Automatic Transmission Fluid) 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.

FLUID TYPES (Continued)
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.
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 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.
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 gaso­line 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.

FLUID TYPES (Continued)
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.
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 tem­perature 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.

TOWING (Continued)
CAUTION: Do not damage brake lines, exhaust sys­tem, shock absorbers, sway bars, or any other under vehicle components when attaching towing device to vehicle. Do not attach towing device to front or rear suspension components. Do not secure vehicle to towing device by the use of front or rear suspension or steering components. Remove or secure loose or protruding objects from a damaged vehicle before towing. Refer to state and local rules and regulations before towing a vehicle. Do not allow weight of towed vehicle to bear on lower fascia, air dams, or spoilers.
RECOMMENDED TOWING EQUIPMENT
To avoid damage to bumper fascia and air dams use of a flat bed towing device or wheel lift (Fig. 8) is recommended. When using a wheel lift towing device, be sure the unlifted end of disabled vehicle has at least 100 mm (4 in.) ground clearance. If minimum ground clearance cannot be reached, use a towing dolly. If a flat bed device is used, the approach angle should not exceed 15 degrees.
LOCKED VEHICLE TOWING
When a locked vehicle must be towed with the front wheels on the ground, use a towing dolly or flat bed hauler.
FLAT TOWING WITH TOW BAR
Three speed automatic transaxle vehicles can be flat towed at speeds not to exceed 40 km/h (25 mph) for not more than 25 km (15 miles). The steering col­umn must be unlocked and gear selector in neutral.
Five speed manual transaxle vehicles can be flat towed at any legal highway speed for extended dis­tances. The gear selector must be in the neutral posi­tion.
FLAT BED TOWING TIE DOWNS
CAUTION: Do not tie vehicle down by attaching chains or cables to suspension components or engine mounts, damage to vehicle can result.
JR vehicles can be tied to a flat bed device using the reinforced loops located under the front and rear bumpers on the drivers side of the vehicle. There are also four reinforced elongated holes for T or R hooks located on the bottom of the front frame rail torque boxes behind the front wheels and forward of the rear wheels inboard of the rocker panel weld seam.

FRONT SUSPENSION
DESCRIPTION - FRONT SUSPENSION
This vehicle’s front suspension is a short long arm (SLA) design used in conjunction with a gas pressur­ized shock absorber and coil spring assembly (Fig. 1).
SLA offers three advantages over the customary MacPherson strut system for front-wheel-drive vehi­cles.
Better handling through geometry that keeps
the tires more perpendicular to the road
Better noise isolation
Better ride through reduced friction
The upper control arm of the vehicle is mounted using rubber isolation bushings to an aluminum cast­ing which is attached to the shock tower using 4 mounting bolts. This aluminum casting is also used as the upper mount for the front shock/coil spring assembly. The shock absorber is isolated from the aluminum bracket using a microcellular urethane
isolator. The lower control arm is mounted to the vehicle’s front suspension crossmember using 2 through bolts per control arm. The lower control arm is also isolated from the vehicle using 2 rubber bush­ings of unique design for the front and rear mounting location. The bottom of the shock absorber is mounted to the lower control arm by a clevis bracket which is part of the shock absorber assembly. The clevis bracket is mounted to and isolated from the lower control arm using a rubber isolation bushing and a through-bolt. The front steering knuckle is mounted to the vehicle by a ball joint located in the upper and lower control arms.
A sealed for life front hub and bearing assembly is attached to the front steering knuckle. The outer C/V joint assembly is splined to the front hub and bear­ing assembly and is retained by a nut, nut retainer and cotter pin.

OPERATION - FRONT SUSPENSION
The front suspension allows each front wheel on vehicle to adapt to different road surfaces and condi­tions without affecting the control of the vehicle. Each side of the front suspension is allowed to move independently from the other. Both sides of the front suspension are allowed to pivot so the vehicle can be steered in the direction preferred. Steering of the vehicle is provided by a rack and pinion steering gear which is connected directly to each steering knuckle by an outer tie rod.
WARNING
WARNING: DO NOT REMOVE A SHOCK ROD NUT WHILE THE SHOCK ASSEMBLY IS INSTALLED IN VEHICLE, OR BEFORE THE SHOCK ASSEMBLY SPRING IS COMPRESSED.
CAUTION
CAUTION: Only frame contact hoisting equipment should be used on this vehicle. All vehicles have a fully independent rear suspension. Vehicles must not 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

DIAGNOSIS AND TESTING - HUB AND BEARING
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 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. The bearing is not service­able.
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 2 - BRAKES/HY­DRAULIC-MECHANICAL/ROTOR - DIAGNOSIS AND TESTING).

LOWER BALL JOINT
DESCRIPTION
The ball joint used in the lower control arm of this vehicle is a sealed for life ball joint. The ball joint can not be replaced as a separate component of the lower control arm assembly. If the ball joint is deter­mined to be defective it will require replacement of the complete lower control arm assembly.
The lower ball joint connection to the steering knuckle is achieved by an interference fit created by the tapered stud of the ball joint and a tapered hole in the steering knuckle. The ball joint stud is retained in the steering knuckle using a castle nut and a cotter pin. The cotter pin is used for positive retention of the castle nut.
The lower ball joint is lubricated for life at the time it is assembled in the lower control arm.
NOTE: The ball joint does not require any type of additional lubrication for the life of the vehicle. No attempt should be made to ever add any lubrication to the lower ball joint.
DIAGNOSIS AND TESTING - LOWER BALL JOINT
(1) Raise the vehicle on jack stands or centered on a frame contact type hoist. (Refer to LUBRICATION & MAINTENANCE/HOISTING - SERVICE PROCE­DURE).
(2) Install a dial indicator on the vehicle so it is contacting the top surface of the steering knuckle near the lower ball joint stud castle nut.
(3) Grab wheel and tire assembly and push it up and down firmly.
(4) Record the amount of up and down movement of the steering knuckle recorded on the dial indicator.
(5) Replace lower control arm if the movement in the lower control arm exceeds 1.5 mm (.059 in.).
LOWER BALL JOINT SEAL BOOT
CAUTION: Under no circumstances can a lower ball joint seal boot be replaced if it is determined that the vehicle had been driven with the seal boot dam­aged. If the vehicle has been driven with a damaged seal boot contamination of the ball joint has occurred. When contamination of the ball joint has occurred the lower control arm must be replaced. This is to ensure excessive wear of the ball joint does not occur from the contamination present in the ball joint.
CAUTION: Excessive wear in the ball joint can lead to a separation of the ball joint from the lower con­trol arm.
CAUTION: The procedure below must be carefully followed when replacing the ball joint seal in the event it is damaged while servicing a vehicle.
CAUTION: The ball joint used in the lower control arm of this vehicle is a lubricated for life ball joint. This ball joint does not required any additional lubrication for the life of the vehicle. Do not alter the lower control arm or ball joint in an attempt to lubricate the lower control arm ball joint. If it is determined that the ball joint is lacking proper lubri­cation, the lower control arm will need to be replaced.
(1) Remove lower control arm assembly from vehi­cle. (Refer to 2 - SUSPENSION/FRONT/LOWER CONTROL ARM - REMOVAL).
(2) Wrap a shop towel around the ball joint and seal boot. This is to prevent dirt and cleaning solvent to enter ball joint when cleaning area around ball joint.
(3) Using ONLY a solvent such as Mopar Foamy Engine Degreaser or an equivalent, thoroughly clean lower control arm in area around ball joint and seal. Then using a shop towel saturated with the engine degreaser, carefully wipe off the ball joint seal boot.

LOWER CONTROL ARM
DESCRIPTION
The lower control arm is a ductile iron casting using 2 rubber bushings to isolate it from the front suspension crossmember and body of the vehicle. The isolator bushings consist of 2 metal encased rubber isolated pivot bushings. 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 the front suspension crossmember using a through-bolt. The lower control arms are inter-connected through a linked rubber isolated sway bar.
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. It also provides a lower mounting point for the shock assembly.
DIAGNOSIS AND TESTING - LOWER CONTROL ARM
If damaged, the lower control arm casting is ser­viced only as a complete component. Inspect lower control arm for signs of damage from contact with the ground or road debris. If lower control arm shows any sign of damage, inspect lower control arm for distortion. Do not attempt to repair or straighten
a broken or bent lower control arm.
The replaceable components of the lower control arm are: the ball joint grease seal and the control arm bushings. Inspect both control arm bushings for severe deterioration, and replace if required.
Inspect the lower ball joint for wear. Use the wear inspection procedure in the diagnosis and testing sec­tion in this group of service manual to determine if the wear is excessive and ball joint (lower control arm) replacement is required.
Service procedures to replace these components are detailed in the specific component removal and installation sections in this group of the service man­ual.

SHOCK ASSEMBLY
DESCRIPTION - SHOCK ASSEMBLY
The front shock assembly and suspension of the vehicle is supported by coil springs positioned around shock absorbers. The springs are contained between an upper seat located in the upper mounting bracket and a lower spring seat on the shock absorber.
The top of each shock absorber is bolted to a cast shock absorber/upper control arm bracket which is bolted to the shock tower of the vehicle using 4 mounting bolts.
The bottom of the shock absorber attaches to a cle­vis bracket using a pinch bolt. The clevis bracket attaches to the lower control arm of the vehicle using a through-bolt and prevailing torque nut.
If shock absorbers require replacement, be sure that they are replaced with shock absorbers meeting the correct specifications for the particular vehicle.
A coil spring is housed within each shock assembly. Coil springs are rated separately for each corner or side of the vehicle depending on optional equipment and type of vehicle service. If the coil springs require replacement, be sure that the springs needing replacement, are replaced with springs meeting the correct load rating and spring rate for the vehicle and its specific options.
The components of the shock assembly listed below
are serviceable if found to be defective (Fig. 37):
Upper mounting bracket
Upper spring isolator
Dust shield
Cup
Jounce bumper

SHOCK ASSEMBLY (Continued)
OPERATION - SHOCK ASSEMBLY
The shock absorber assembly cushions the ride of the vehicle, controlling vibration, and 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 bracket and shock absorber.
The jounce bumper limits suspension travel and metal-to-metal contact under full jounce condition.
The shock absorber dampens jounce and rebound motions of the coil spring and suspension.
DIAGNOSIS AND TESTING - SHOCK ASSEMBLY (FRONT)
(1) Inspect for damaged or broken coil springs (Fig. 38).
(2) Inspect for torn or damaged shock absorber dust boots (Fig. 38).
(3) Lift the dust boot and inspect the shock absorber for evidence of fluid running from the upper end of fluid reservoir. (Actual leakage will be a stream of fluid running down the side and dripping off the lower end of the shock absorber). A slight amount of seepage between the shock absorber rod and the seal is not unusual and does not affect per­formance of the shock absorber. Also inspect jounce bumpers for signs of damage or deterioration (Fig.
38).

HUB / BEARING
DESCRIPTION
The hub and bearing is a combined rear wheel hub and wheel bearing unit. All vehicles are equipped with permanently lubricated and sealed for life rear hub and bearing assemblies. There is no periodic lubrication or maintenance recommended for these units.
The hub and bearing is mounted to the rear knuck­le’s spindle using a retaining nut. The tire and wheel assembly, and rear brake drum or disc attaches to the studs protruding from the hub flange with wheel mounting studs.
OPERATION
The hub and bearing has internal bearings that allow it to rotate with the tire and wheel.
DIAGNOSIS AND TESTING - HUB AND BEARING
The rear hub and bearing assembly is designed for the life of the vehicle and should require no mainte­nance. The following procedure may be used for eval­uation of bearing condition.
With wheel and brake drum removed, rotate flanged outer ring of hub. Excessive roughness, lat­eral play or resistance to rotation may indicate dirt intrusion or bearing failure. If the rear wheel bear­ings exhibit these conditions during inspection, the hub and bearing assembly should be replaced.
Damaged bearing seals and resulting excessive grease loss may also require bearing replacement. Moderate grease loss from bearing is considered nor­mal and should not require replacement of the hub and bearing assembly.
REMOVAL
(1) Raise vehicle. (Refer to LUBRICATION & MAINTENANCE/HOISTING - STANDARD PROCE­DURE).
(2) Remove rear wheel and tire assembly.
(3) If equipped with rear disc brakes, remove the rear brake caliper and rotor. (Refer to 5 - BRAKES/ HYDRAULIC/MECHANICAL/ROTORS - REMOV­AL). Remove the brake rotor by pulling the rotor straight off the wheel mounting studs.
(4) If equipped with rear drum brakes, remove the brake drum. (Refer to 5 - BRAKES/HYDRAULIC/ MECHANICAL/DRUM - REMOVAL)
(5) Remove dust cap from rear hub and bearing assembly by prying it off.
(6) Remove hub and bearing retaining nut.
(7) Remove rear hub and bearing from the spindle by pulling it straight off the spindle.

(6) Lower the vehicle.
KNUCKLE
DESCRIPTION
A cast iron rear knuckle is attached to each side of the vehicle through the upper control arm and ball joint, the rear shock assembly, the lateral links and the trailing link. The knuckle serves as a mounting point for the rear hub and bearing, tire and wheel, and rear brakes.
OPERATION
The knuckle moves up and down with the tire and wheel under jounce and rebound conditions while acting as a mount for the rear hub and bearing, tire and wheel, and rear brakes. The lateral movement of the rear knuckle is controlled using two lateral arms attached to the bottom of the knuckle and by the upper control arm attached to the top of the knuckle.
DIAGNOSIS AND TESTING - KNUCKLE
Inspect the knuckle for physical damage. If it is determined that the knuckle is cracked, bent or bro­ken when servicing the vehicle, no attempt is to be made to repair or to straighten the knuckle. The rear knuckle is not a repairable component of the rear suspension and must be replaced if found to be dam­aged in any way.

INSPECTION
Inspect the control arm for physical damage. If it is determined that the upper control arm is broken or bent, the upper control arm must be replaced. The rear suspension upper control arm is not a repairable component and no attempt is to be made to repair or to straighten it. The upper control arm must be replaced if found to be damaged in any way.
Inspect the control arm pivot bushings for deterio­ration. If found to need replacement, the upper con­trol arm is to be replaced.
The rear control arm, control arm bushings, and pivot bar are serviced as a complete assembly on this vehicle. Do not attempt to disassemble the control arm from the pivot bar to service the rear control arm bushings.
The only component on the upper control arm that is serviceable is the rear upper ball joint and its seal.

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 (using special procedure)
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 90
JR 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.

CROSS CASTER
Cross caster is the difference between left and
right caster.

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.
Although toe-out on turns is an important angle, it is generally not necessary to check or adjust when performing a wheel alignment.
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 92
JR 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 - PRE-WHEEL ALIGNMENT INSPECTION
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 torque.
(6) Inspect the 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). If curb height is out of specifications, check for broken or sagged springs.
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.

STANDARD PROCEDURE - WHEEL ALIGNMENT
(1) Position the vehicle on an alignment rack.
(2) Perform the PRE-WHEEL ALIGNMENT INSPECTION. (Refer to 2 - SUSPENSION/WHEEL ALIGNMENT - STANDARD PROCEDURE).
(3) 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) Compare the measurements to specifications listed in the following CURB HEIGHT SPECIFICA­TIONS chart.
REAR CAMBER AND TOE
Rear Camber on this vehicle is adjustable. The rear camber on this vehicle is adjusted using the adjusting screw located in the forward and rear lat­eral links of the vehicles rear suspension (Fig. 7).
CAUTION: When checking the rear alignment on this vehicle, the alignment rack must be equipped with rear skid plates.
(1) For either rear wheel needing alignment, loosen the adjusting screw jam nuts (Fig. 7) on both the front and the rear lateral links.
(4) Read the vehicle’s current front and rear align­ment settings. Compare the vehicle’s current align­ment settings to the vehicle specifications for camber, caster and toe-in. (Refer to 2 - SUSPENSION/ WHEEL ALIGNMENT - SPECIFICATIONS).
NOTE: Set the rear wheel alignment first before pro­ceeding to the front to set the front wheel align­ment.
(5) If rear camber or toe is not within specifica­tions, proceed to REAR CAMBER AND TOE below. If rear camber and toe are within specifications, but front camber and caster are not, proceed to FRONT CAMBER AND CASTER which can be found follow­ing REAR CAMBER AND TOE. If rear camber and toe, and front camber and caster are within specifi­cations, proceed to FRONT TOE.
Rear Caster on this vehicle is not adjustable and is not shown as an alignment specification.
CAUTION: Do not attempt to adjust the vehicle’s wheel alignment by heating, bending or modifying any component of the suspension.

Dimensions
(2) Rough-in the rear camber setting as close as possible to the preferred specification by mainly adjusting the rear lateral link adjusting screw (Fig.
7). Some adjustment of the forward lateral link adjusting screw will also be required to get the rear camber setting to the preferred specification. (Refer to 2 - SUSPENSION/WHEEL ALIGNMENT - SPEC­IFICATIONS).
(3) Adjust the forward lateral link adjusting screw (Fig. 7)to set rear toe to the preferred specification. (Refer to 2 - SUSPENSION/WHEEL ALIGNMENT ­SPECIFICATIONS).
NOTE: Adjusting toe will cause a slight change in the camber setting. If during the setting of toe, cam­ber is no longer at the preferred specification, con­tinue to adjust camber and toe until both are at their preferred specifications.
(4) While holding adjustment screws from turning, use a crow foot and torque wrench, and tighten all lateral link adjusting screw jam nuts to a torque of 92 N·m (68 ft. lbs.). This will securely hold the adjusting screws from turning.
(5) Proceed to FRONT CASTER AND CAMBER, or FRONT TOE if front caster and camber are within specifications.
FRONT CAMBER AND CASTER
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 a procedure listed here. Before performing the camber adjustment procedure, inspect the suspension components for any signs of damage or bending.
CAMBER ADJUSTMENT PROCEDURE
(1) Open the hood and mark the position of all four shock assembly mounting bolts on the shock tower (Fig. 9) on the side of the vehicle requiring front camber adjustment.
Fig. 9 Shock Assembly Mounting Bolts
1 - SHOCK TOWER 2 - MOUNTING BOLTS
(2) Raise the vehicle by the frame until the tires and front suspension are not supporting the weight of the vehicle.
(3) Loosen the shock assembly mounting bolts on the side marked in step 1. Loosen the bolts enough to allow adequate space for removal of the plastic locat­ing pins that align the upper mounting bracket with the shock tower.
(4) Remove and discard both plastic locating pins from the shock assembly upper mounting bracket using a punch or pliers.
NOTE: Do not leave the plastic locating pins in the cavity of the shock tower or mount. Objectionable noise may result.

HALF SHAFT
DESCRIPTION
This vehicle is equipped with an unequal length halfshaft system (Fig. 1). These halfshafts consist of two constant velocity joints connected by a solid shaft. A solid short interconnecting shaft is used on the left side. A long solid interconnecting shaft is used on the right side.
Some halfshafts use a tuned rubber damper weight. When replacing a halfshaft assembly, 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 inner tripod joint of both halfshafts is splined into the transaxle side gears. The inner tripod joints are retained in the side gears of the transaxle 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 steel hub nut.
OPERATION
Halfshaft assemblies are designed to transmit power from the transaxle to the front wheels, while allowing for powertrain and suspension flex.
DIAGNOSIS AND TESTING
HALFSHAFT DIAGNOSIS
VEHICLE INSPECTION
(1) Check for grease in the vicinity of the inboard tripod joint and outboard C/V joint; this is a sign of inner or outer joint seal boot or seal boot clamp dam­age.
(2) A light film of grease may appear on the right inner tripod joint seal boot; this is considered normal and should not require replacement of the seal boot.
