NOTE: Before releasing the tension the compressor
has on the spring, using the following figure as ref-
erence (Fig. 50), make sure the upper spring seat,
coil spring and strut clevis bracket are all lined up
properly (within 5É of one another).
(12) Slowly release the tension from the coil spring
by backing off the compressor drive fully. As the ten-
sion is relieved, make sure the upper mount, pivot
bearing and upper seat are align properly. Remove
the clamp from the lower end of the coil spring and
strut. Push back the spring compressor upper and
lower hooks, then remove the strut assembly from
the spring compressor.
(13) Install strut assembly on the vehicle. (Refer to

TION)
INSTALLATION - STRUT ASSEMBLY
CAUTION: Front strut coil springs are side-oriented.
When installing a strut assembly, make sure the
strut being installed has the correct coil spring for
that side of the vehicle. Springs on the left side of
the vehicle have a left-hand wind top-to-bottom
while springs on the right side have a right-hand
wind top-to-bottom (Fig. 49). Do not interchange the
two sides.(1) Install strut assembly into strut tower, aligning
and installing the 3 studs on the upper strut mount
into the holes in shock tower. Install the 3 upper
strut mount attaching nut/washer assemblies (Fig.
43). Then using a crow foot. tighten the 3 attaching
nuts to a torque of 28 N´m (250 in. lbs.).
CAUTION: The steering knuckle to strut assembly
attaching bolts are serrated and must not be turned
during installation. Install nuts while holding bolts
stationary in the steering knuckles.
NOTE: The strut clevis-to-steering knuckle bolts are
installed differently on each side of the vehicle. Left
hand side bolts are to be installed from vehicle rear
to front. Right side bolts are to be installed from
vehicle front to rear.
(2) Align strut assembly with steering knuckle.
Position arm of steering knuckle into strut assembly
clevis bracket. Align the strut assembly clevis
bracket mounting holes with the steering knuckle
mounting holes. Install the 2 strut assembly to steer-
ing knuckle attaching bolts (Fig. 42).If strut assem-
bly is attached to steering knuckle using a cam
bolt, the cam bolt must be installed in the lower
slotted hole on strut clevis bracket.Tighten the
strut clevis-to-steering knuckle attaching bolts to a
torque of 81 N´m (60 ft. lbs.) plus an additional 1/4
(90É) turn after specified torque is met.
(3) Install the stabilizer bar link mounting stud
through the bracket on the strut assembly (Fig. 41).
CAUTION: When installing the nut on the mounting
stud of the stabilizer bar link, do not allow the stud
to rotate in it's socket. Hold the stud from rotating
by placing an open-end wrench on the flat
machined into the stud (Fig. 41).
(4) Hand thread the nut on the end of the stabi-
lizer bar link stud. Hold the stud from turning by
placing an open-end wrench on the flat machined
into the link's mounting stud, then tighten the nut
while holding the wrench in place (Fig. 41). Tighten
the nut to a torque of 88 N´m (65 ft. lbs.).
(5) Install the hydraulic brake hose and speed sen-
sor cable routing brackets on the strut assembly
brackets (Fig. 40). Tighten the routing bracket
attaching bolts to a torque of 13 N´m (10 ft. lbs.).
(6) Install the wheel/tire assembly on the vehicle.
(7) Install and tighten the wheel mounting stud
nuts in proper sequence until all nuts are torqued to
half specification. Then repeat the tightening
sequence to the full specified torque of 135 N´m (100
ft. lbs.).

inner tie rod.
(5) Remove steering wheel clamp.
(6) Remove the alignment equipment.
(7) Road test the vehicle to verify the steering
wheel is straight and the vehicle does not wander or
pull.STANDARD PROCEDURE - CURB HEIGHT
MEASUREMENT
The wheel alignment is to be checked and all align-
ment 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 stan-
dard 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 measure-
ment 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.
(1) Measure from the inboard edge of the wheel
opening fender lip directly above the wheel center
(spindle), to the floor or alignment rack surface.
(2) When measuring, the maximum left-to-right
differential is not to exceed 12.5 mm (0.5 in.).
(3) Compare the measurements to the specifica-
tions listed in the following Curb Height Specifica-
tions charts.

away from the outer C/V joint of the half shaft
assembly while pulling the joint out of the hub bear-
ing.
(13) Support the outer end of the half shaft assem-
bly. Insert a pry bar between inner tripod joint and
transaxle case (Fig. 7). Pry against inner tripod joint,
until tripod joint retaining snap-ring is disengaged
from transaxle side gear.
(14) Hold inner tripod joint and interconnecting
shaft of half shaft assembly. Remove inner tripod
joint from transaxle, by pulling it straight out of
transaxle side gear and transaxle oil seal (Fig. 8).
When removing tripod joint, do not let spline or
snap-ring drag across sealing lip of the trans-
axle to tripod joint oil seal.
INSTALLATION
(1) Thoroughly clean spline and oil seal sealing
surface, on tripod joint. Lightly lubricate oil seal
sealing surface on tripod joint with fresh clean trans-
mission lubricant.
(2) Holding half shaft assembly by tripod joint and
interconnecting shaft, install tripod joint into trans-
axle side gear as far as possible by hand (Fig. 8).
(3) Grasp inner tripod joint an interconnecting
shaft. Forcefully push the tripod joint into side gear
of transaxle, until snap-ring is engaged with trans-
axle side gear.Test that snap-ring is fully
engaged with side gear by attempting to
remove tripod joint from transaxle by hand. If
snap-ring is fully engaged with side gear, tripod
joint will not be removable by hand.(4) Clean all debris and moisture out of steering
knuckle, in the area were outer CV joint will be
installed into steering knuckle.
(5) Ensure that front of outer CV joint which fits
against the face of the hub and bearing is free of
debris and moisture before installing outer CV joint
into hub and bearing assembly (Fig. 9).

front and rear drive units. The unit is totally sealed
and partially filled with silicone fluid. There is no
adjustment, maintenance or fluid checks required
during the life of the unit.
The overrunning clutch allows the rear wheels to
overrun the front wheels during a rapid front wheel
lock braking maneuver. The overrunning action pre-
vents any feed-back of front wheel braking torque to
the rear wheels. It also allows the braking system to
control the braking behavior as a two wheel drive
(2WD) vehicle.
The overrunning clutch housing has a separate oil
sump and is filled independently from the differen-
tial. The fill plug is located on the side of the over-
running clutch case. When filling the overrunning
clutch with lubricant use MopartATF+4 (Automatic
Transmission FluidÐType 9602) or equivalent.
The differential assembly contains a conventional
open differential with hypoid ring gear and pinion
gear set. The hypoid gears are lubricated by SAE
80W-90 gear lubricant.DIAGNOSIS AND TESTING
DIAGNOSIS AND TESTING - REAR DRIVELINE
MODULE NOISE
Different sources can be the cause of noise that the
rear driveline module assembly is suspected of mak-
ing. Refer to the following causes for noise diagnosis.
DRIVELINE MODULE ASSEMBLY NOISE
The most important part of driveline module ser-
vice is properly identifying the cause of failures and
noise complaints. The cause of most driveline module
failures is relatively easy to identify. The cause of
driveline module noise is more difficult to identify.
If vehicle noise becomes intolerable, an effort
should be made to isolate the noise. Many noises that
are reported as coming from the driveline module
may actually originate at other sources. For example:
²Tires
²Road surfaces
²Wheel bearings

CAUTION
CAUTION: During service procedures, grease or
any other foreign material must be kept off brake
shoe assemblies, and braking surfaces of brake
rotor or drum, and external surfaces of hub and
bearing assembly.
CAUTION: Handling of brake rotors and calipers
must be done in such a way as to avoid damage to
the rotor and scratching or nicking of brake lining
on the brake shoes.
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. Also, NO holes can be drilled
into the front shock tower in the area shown in (Fig.
1), for the installation of any metal fasteners into
the shock tower. Because of the minimum clear-ance in this area (Fig. 1), installation of metal fas-
teners could damage the coil spring coating and
lead to a corrosion failure of the spring. If a plastic
clip is missing, or is lost or broken during servicing
a vehicle, replace only with the equivalent part
listed in the Mopar parts catalog.
CAUTION: Only the recommended jacking or hoist-
ing positions for this vehicle are to be used when-
ever it is necessary to lift a vehicle. Failure to raise
a vehicle from the recommended locations could
result in lifting a vehicle by the hydraulic control
unit mounting bracket. Lifting a vehicle by the
hydraulic control unit mounting bracket will result
in damage to the mounting bracket and the hydrau-
lic control unit.

plug from the adjustment hole in each brake support
plate to provide visual access of the brake adjuster
star wheel.
To eliminate the condition where maximum adjust-
ment of the rear brake shoes does not allow the auto-
matic adjuster to operate when tested, back the star
wheel off approximately 30 notches. It will be neces-
sary to hold the adjuster lever away from the star
wheel to permit this adjustment.
Have the helper apply the brakes. Upon applica-
tion of the brake pedal, the adjuster lever should
move down, turning the adjuster star wheel. Thus, a
definite rotation of the adjuster star wheel can be
observed if the automatic adjuster is working prop-
erly. If one or more adjusters do not function prop-
erly, the respective drum must be removed for
adjuster servicing.
BRAKE LINES
DESCRIPTION - BRAKE TUBES AND HOSES
The brake tubes are steel with a corrosion-resis-
tant nylon coating applied to the external surfaces.
The flex hoses are made of reinforced rubber with fit-
tings at each end.
The primary and secondary brake tubes leading
from the master cylinder to the ABS ICU Hydraulic
Control Unit (HCU) or the non-ABS junction block
have a special flexible section. This flexible section is
required due to cradle movement while the vehicle is
in motion (The ICU and non-ABS junction block are
mounted to the cradle).If replacement of these
lines is necessary, only the original factory
brake line containing the flexible section must
be used.
OPERATION - BRAKE TUBES AND HOSES
The purpose of the chassis brake tubes and flex
hoses is to transfer the pressurized brake fluid devel-
oped by the master cylinder to the wheel brakes of
the vehicle. The flex hoses are made of rubber to
allow for the movement of the vehicle's suspension.
INSPECTION - BRAKE TUBES AND HOSES
Flexible rubber hose is used at both front brakes
and at the rear axle. Inspection of brake hoses
should be performed whenever the brake system is
serviced and every 7,500 miles or 12 months, which-
ever comes first (every engine oil change). Inspect
hydraulic brake hoses for surface cracking, scuffing,
or worn spots. If the fabric casing of the rubber hose
becomes exposed due to cracks or abrasions in the
rubber hose cover, the hose should be replaced imme-
diately. Eventual deterioration of the hose can take
place with possible burst failure. Faulty installation
can cause twisting, resulting in wheel, tire, or chassis
interference.
The brake tubing should be inspected periodically
for evidence of physical damage or contact with mov-
ing or hot components.
The flexible brake tube sections used on this vehi-
cle in the primary and secondary tubes from the
master cylinder to the ABS hydraulic control unit
connections must also be inspected. This flexible tub-
ing must be inspected for kinks, fraying and contact
with other components or with the body of the vehi-
cle.
