GENERAL INFORMATION

Throughout this group, references may be made to a particular L.H. platform vehicle by letter or number designation. A chart showing the breakdown of these designations is included in the Introduction section at the front of this Service Manual.
The L.H. platform vehicles have a MacPherson gas pressurized strut front suspension design (Fig. 1). The MacPherson strut shock absorber assembly in­cludes the following components. A rubber isolated top mount, seat and bearing assembly and a coil spring insulator. The MacPherson strut assembly is attached to the vehicle at the shock tower using 3 studs which are part of the isolated top mount. The lower end of the MacPherson strut assembly is at­tached to the upper leg of the steering knuckle. At­tachment of the MacPherson strut assembly to the steering knuckle is by 2 serrated bolts. A forged lower

FRONT SUSPENSION

FRONT SUSPENSION MAJOR COMPONENTS (FIG. 2)
STRUT ASSEMBLY
The front strut and suspension of the vehicle is supported by coil springs positioned around the struts. The springs are contained between an upper seat, located just below the top strut mount assembly (Fig. 2) and a lower spring seat on the strut lower housing.
The top of each strut assembly is bolted to the upper fender reinforcement (shock tower) through a rubber isolated mount.
The bottom of the strut assembly attaches to the top of the steering knuckle with two serrated through bolts and prevailing torque nuts. Caster is a fixed setting (net build) on all vehicles and is not adjustable.

STEERING KNUCKLE

The steering knuckle (Fig. 2) is a single casting with legs machined for attachment to the front strut assembly and lower control arm ball joint. The steer­ing knuckle also has machined abutments on the casting to support and align the front brake caliper assembly. The knuckle also holds the front drive shaft outer C/V joint hub and bearing assembly. The hub is positioned through the bearing and knuckle, with the constant velocity stub shaft splined through the hub. The outer C/V joint is retained to the hub and bearing assembly using a prevailing torque nut.

LOWER CONTROL ARM

The lower control arm (Fig. 2) is a steel forging with 2 rubber bushings isolating the lower control arm from the front cradle assembly. The isolator bushings consist of a metal encased pivot bushing and a solid rubber tension strut bushing. The lower control arm is bolted to the cradle assembly using a pivot bolt through the center of the rubber pivot bushing and at the tension strut isolator bushing (Fig. 2).
The ball joint is an integral part of the control arm and has a non-tapered stud with a notch for clamp
bolt clearance. The stud is clamped and locked into the steering knuckle leg with a clamp bolt. The ball joint used on the L.H. Platform vehicle is non­serviceable and if defective must be serviced as part of the lower control arm.

DRIVESHAFTS

A left and right driveshaft is attached inboard to the transaxle differential output (or stub) shaft, and outboard to the driven wheel hub and bearing assem­bly.
To deliver driving force from the transaxle to the front wheels during turning maneuvers and suspen­sion movement. Both shafts are constructed with con­stant velocity universal joints at both ends.
Both shafts have a Tripod (sliding) joint at the transaxle end and C/V joints (with splined stub shafts) on the hub ends. Due to the transaxle loca­tion the connecting shafts between the C/V joints are of different length and construction. The left shaft is longer than the right. Both the left and right drive shafts are of the solid bar type. No tubular drive shafts are used on any available L.H. platform ve­hicle and powertrain combinations.

TENSION STRUTS

The L.H. platform vehicle uses a tension strut (Fig.
2) on each side of the vehicles front suspension. The tension strut controls longitudinal (for-and-aft) move­ment of the front wheels of the vehicles. Controlling the longitudinal movement of the wheels reduces harshness when wheels hit sudden irregularities in the road surface.

STABILIZER BAR (SWAY BAR)

The stabilizer bar (Fig. 2) interconnects the front strut assemblies of the vehicle. The purpose of a stabilizer bar is to control the body roll of the vehicle.

STABILIZER BAR LINK ASSEMBLY

The stabilizer bar link assembly (Fig. 2) is used to attach the stabilizer bar to the front strut assemblies. This reduces the fore-and-aft rate of the sway bar from the rest of the suspension.

FRONT SUSPENSION SERVICEABLE COMPONENTS

The following components may be replaced either
individually or as an assembly.
Gas pressurized front strut must be replaced as an assembly. The strut is not serviceable. It is not neces­sary to replace strut assemblies in pairs.
Strut assembly upper mounts are replaceable.
Bearing and seat assemblies may be replaced indi-
vidually.
Coil spring lower isolator may be replaced indi­vidually.
Front wheel hub and bearing assemblies are indi­vidually replaceable.
Lower control arm bushings are serviced as indi­vidual components of lower control arm assembly, and do not require replacement of lower control arm if defective.
Tension struts are replaceable as are the tension strut to cradle assembly isolator bushings. Tension strut washers at the lower control arm and cradle are replaceable, with proper approved replacement parts
ONLY.
Front stabilizer bar is replaceable. Front stabilizer bar isolator bushings, clamps and stabilizer bar link assemblies are also replaceable.
Driveshaft seal and boot replacement, is the only service to be performed on the driveshaft assemblies. Any failure of an internal driveshaft component will require the replacement of the driveshaft assembly.

FRONT WHEEL ALIGNMENT

Front wheel alignment is the proper settings of all the interrelated suspension angles affecting the run­ning and steering of the front wheels of the vehicle.
On the L.H. platform vehicle the only adjust­able suspension setting is wheel TOE.

Wheel Alignment Service Procedure ............ 7
The method of checking front alignment will vary depending on the type of equipment being used. The instructions furnished by the manufacturer of the equipment should always be followed. With the excep­tion that the alignment specifications recommended by Chrysler Corporation be used.
There are six basic factors which are the foundation to front wheel alignment. These are vehicle height, caster, camber, toe-in, steering axis inclination and toe-out on turns. Of the six basic factors only TOE
IN is mechanically adjustable on the L.H. plat­form vehicle (Fig. 1).
CAUTION: Do not attempt to modify any suspension or steering components by heating or bending of the component.
Wheel alignment adjustments can only be made for the Toe In setting on the L.H. platform vehicles.
Toe is measured in degrees or inches and is the
distance the front edges of the tires are closer (or farther apart) than the rear edges. See Front Wheel Drive Specifications for Toe settings.

PRE-ALIGNMENT

Before any attempt is made to change or correct front wheel alignment. The following inspection and necessary corrections must be made on those parts which influence the steering of the vehicle.
(1) Check and inflate tires to recommended pres­sure. All tires should be the same size and in good condition and have approximately the same wear. Note type of tread wear which will aid in diagnosing, see Wheels and Tires, Group 22.
(2) Check front wheel and tire assembly for radial runout.
(3) Inspect lower ball joints and all steering linkage for looseness.
(4) Check for broken or front and rear springs.
Alignment must only be checked after the vehicle has had the following checked or adjusted. Tires set
Page 7
to recommended pressures, full tank of fuel, no pas­senger or luggage compartment load and is on a level floor or alignment rack.
Just prior to each alignment reading. The vehicle should be bounced (rear first, then front) by grasping bumper at center and jouncing each end an equal number of times. Always release bumpers at bottom of down cycle.

GENERAL INFORMATION

All L.H. platform vehicles are equipped with an un­equal length drive shaft system (Fig. 1). The left side of the vehicle is equipped with a longer drive shaft than the right side of the vehicle. The L.H. platform uses solid interconnecting shafts on both sides of the vehicle.
The driveshaft assemblies are three piece units. Each driveshaft has a Tripod Joint, an Interconnect­ing Shaft and a outer C/V joint. The Tripod Joint is splined onto the transaxle stub shaft, and the outer C/V joint has a stub shaft that is splined into the front wheel hub and bearing assembly.
Outer C/V Joint Sealing Boot Service .......... 50
Service Procedures ....................... 42
Servicing Driveshafts ...................... 42
The inner tripod joint boots, on the L.H. plat­form vehicle are of different materials. The left inner boot is made of high temperature applica­tion silicone, and the right inner boot is made of hytrel plastic. When drive shaft boots are re­placed be sure boots of the correct material are used on the correct side of the vehicle.
The driveshafts used on the L.H. platform vehicles are supplied by Saginaw Division for all available drivelines.

SERVICE PROCEDURES

Procedures for removal and installation of drive­shafts on the L.H. platform vehicles are different and somewhat easier, then those on other front wheel drive vehicles. This new drive shaft design, allows both drive shafts to be removed from the vehicle without dismantling the transaxle.
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, pulling or pushing the ends can cut boots or damage C/V joints. The L.H. platform driveshafts use no retention system to retain the spider assembly in the tripod housing. During re­moval and installation procedures always support both ends of the driveshaft to prevent damage or disengag­ing tripod joint. Therefore, do not pull on the intercon­necting shaft when attempting to remove drive shafts from vehicle.

DRIVESHAFT RECONDITIONING PROCEDURE

The only service which is to be performed on the driveshaft assemblies is the replacement of the drive shaft seal boots.
If any failure of internal driveshaft components is diagnosed during a vehicle road test or disassembly of the drive shaft, the drive shaft will need to be re­placed as an assembly.
Note: that lubricant requirements and quanti­ties are different for Inner Joints than for Outer Joints. Use only the recommended lubricants.
See (Fig. 1) for the exploded view of the front drive shaft components and there location in the assembly.
Fig. 17 Tightening Wheel Nuts
(13) Lower vehicle to the ground.
CAUTION: When torquing hub and bearing assem­bly to stub shaft retaining nut, do not exceed the maximum torque of 176 Nzm (130 ft. lbs.). If the maximum torque is exceeded this may result in a failure of the drive shaft.
(14) With the vehicle brakes applied to keep vehicle from moving. Torque the NEW stub shaft to hub and bearing assembly retaining nut to 163 Nzm ± 14 (120 ft. lbs. ± 10) (Fig. 18).

INNER TRIPOD JOINT SEAL BOOT

REMOVE

To remove sealing boots from driveshafts for re­placement, the drive shaft assemblies must be re­moved from the vehicle. See Servicing Driveshaft in this section of the service manual for the required drive shaft removal and replacement procedure.
The Saginaw inner tripod joints used on the L.H. platform vehicles use no internal retention in the tripod housing to keep the spider assembly in the housing. Therefore do not pull on the interconnecting shaft to disengage tripod housing from transmission stub shaft. Removal in this manner will cause dam­age to inboard boots.
(1) Remove the driveshaft requiring boot replace­ment from the vehicle. See Servicing Driveshaft in this section of the service manual for the required drive shaft removal procedure.
Remove large boot clamp which retains inner
(2) tripod joint sealing boot to tripod joint housing (Fig.

GENERAL INFORMATION

The rear suspension used on the L.H. platform is a fully independent rear suspension. The suspension utilizes a MacPherson strut assembly at each rear wheel of the vehicle.
CAUTION: Only frame contact hoisting equipment can be used on L.H. platform vehicles. The L.H. platform vehicles have a fully independent rear sus­pension. The L.H. platform vehicles can 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.
A forged rear spindle bolts to each rear strut as­sembly. The movement of the rear spindle is con­trolled laterally using lateral links going from the front and rear of the spindle to the rear cross mem­ber. Fore and aft movement of the spindle is con­trolled by a trailing arm.
Rear Wheel Toe Setting Procedure ............ 55
Servicing Lateral Links ..................... 69
Servicing Rear Struts ...................... 55
Suspension Coil Springs ...................61
The lateral links and trailing arm have rubber iso­lator bushings at each end. The lateral links are attached to the rear crossmember and spindle, using a common bolt and nut assembly at each end. The trailing arm bolts to the bottom of the spindle and to a bracket attached to the floor pan of the vehicle.
Lateral links, trailing arms and spindles are nor­mally replaced only when the part has been damaged or when the vehicle has been involved in an accident. If a suspension part has been damaged, be sure to check the underbody dimensions of the car. If the underbody dimensions are not correct, the frame of the vehicle must be straightened, before replacement suspension components are installed.
Note: If a rear suspension component becomes bent, damaged or fails, no attempt should be made to straighten or repair it. Always replace with a new component.
