ation of an individual component, refer to the appli-
cable component heading in this section.
STRUT ASSEMBLY (FRONT)
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 cle-
vis 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 assem-
blies upper mount. During steering maneuvers, the
strut assembly (through a pivot bearing in the upper
strut mount) and steering knuckle (through the lower
ball joint) turn as an assembly. The strut assembly is
used to dampen the front suspension and smooth the
ride of the vehicle.
The strut assembly includes the following compo-
nents: A rubber isolated upper mount, an upper
spring seat and bearing, a dust shield, a jounce
bumper, a coil spring, a lower spring isolator and a
strut (Fig. 1). Each component is serviced by remov-
ing the strut assembly from the vehicle and disas-
sembling it.
COIL SPRING
The strut and front suspension of the vehicle is
supported by coil springs positioned around the
upper half of each strut. The springs are contained
between the upper and the lower seats of the strut
assembly.
Coil springs are rated separately for each corner or
side of the vehicle depending on optional equipment
and type of vehicle service. During service procedures
of the strut assembly, if both springs are removed,
mark the springs to ensure installation in its original
position.
NOTE: 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.
STEERING KNUCKLE
The steering knuckle is a single casting with legs
machined for attachment to the front strut assembly
on the top and the lower control arm ball joint on the
bottom (Fig. 1). The steering knuckle also has
machined abutments on the casting to support and
align the front brake caliper assembly.
WHEEL BEARING AND HUB
The knuckle also supports the wheel bearing and
hub (Fig. 1). The wheel hub is pressed into a sealed
for life wheel bearing that is pressed into the steer-
ing knuckle. A retainer plate also holds it in place.
The hub supports the driveshaft outer constant veloc-
ity (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 held on the outer C/V
stub shaft using a nut retainer and cotter pin.
The wheel bearing is a Unit 1 type cartridge bear-
ing that requires no maintenance. The wheel bearing
is serviced separately from the hub.
LOWER CONTROL ARM
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 con-
trol 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 the frame rail of the vehicle.
The left and right lower control arms are intercon-
nected through a linked rubber isolated stabilizer
bar.
The outboard end of each lower control arm con-
nects to the steering knuckle using a ball joint.

DESCRIPTION AND OPERATION (Continued)

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.
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. The bearing is not service-
able.Damaged bearing seals and the resulting excessive
grease loss may also require bearing replacement.
Moderate grease weapage from the bearing is consid-
ered normal and should not require replacement of
the wheel bearing.
To diagnose a bent hub, refer to BRAKE ROTOR in
the DIAGNOSIS AND TESTING section in the
BRAKES service manual group for the procedure on
measuring hub runout.
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 BALL JOINT in this section of this
service manual group.
BALL JOINT
With the weight of the vehicle resting on the road
wheels, grasp the headless grease fitting as shown
(Fig. 4). With no mechanical assistance or added
force, attempt to move the grease fitting. If the ball
joint is worn, the grease fitting will move. If move-
ment is noted, replace the ball joint.

DIAGNOSIS AND TESTING (Continued)

CAUTION: No attempt should be made to service
the headless grease fitting on the ball joint. It has
been purposely snapped off by the manufacturer to
avoid over-greasing.
STABILIZER BAR (FRONT)
Inspect for broken, cracked or distorted stabilizer
bar cushions and retainers. Inspect for worn or dam-
aged stabilizer bar links (Fig. 1).
SERVICE PROCEDURES
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 damag-
ing 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.
REMOVAL AND INSTALLATION
SERVICE WARNINGS AND CAUTIONS
WARNING: DO NOT REMOVE THE STRUT SHAFT
NUT WHILE STRUT ASSEMBLY IS INSTALLED IN
VEHICLE, OR BEFORE THE COIL SPRING IS COM-
PRESSED WITH A COMPRESSION TOOL. THE

CAUTION: Only frame contact hoisting equipment
can be used on this vehicle. All vehicles have a
fully independent rear suspension. The vehicles
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.

(4) Remove the disc brake caliper from the steer-
ing knuckle. The caliper is removed by first tipping
either the top (right side) or bottom (left side) of thecaliper away from the brake rotor, then pulling the
caliper off the opposite end's caliper slide (on the
knuckle) and rotor.
(5) Hang the caliper out of the way using a wire
hanger or cord. Do not support the caliper by letting
it hang by the hydraulic hose.
(6) Remove any retainer clips from the wheel
mounting studs. Remove the brake rotor from the
front hub (Fig. 20).
CAUTION: Do not hammer wheel mounting studs
out of the hub. Damage to the wheel bearing will
occur, leading to premature bearing failure.
(7) Install a wheel mounting nut on the wheel
mounting stud being removed from the hub far
enough so the threads on the stud are even with end
of lug nut. Rotate the hub so the stud requiring
removal is aligned with notch cast into front of the
steering knuckle. Install Remover, Special Tool
C-4150, on hub flange and wheel stud (Fig. 21).
(8) Tighten the remover, pushing the wheel mount-
ing stud out the rear of the hub flange. When the
shoulder of the stud is past the flange, remove the
remover from the hub. Remove the nut from the

STRUT ASSEMBLY (REAR)
The rear strut assemblies support the weight of
the vehicle using coil springs positioned around
struts. The coil springs are contained between the
upper mount of the strut assembly and a lower
spring seat on the body of the strut.
The top of each strut assembly is bolted to the top
of the inner fender through a rubber isolated mount.
The bottom of the strut assembly attaches to the rear
knuckle using 2 thru-bolts with prevailing torque
nuts.
The rear strut assembly includes the following
components (Fig. 1): A rubber isolated upper mount,
a dust shield, a jounce bumper, a coil spring, a lower
spring isolator, and a strut. Any component in need
of service requires removal of the strut assembly
from the vehicle and disassembly of it.
COIL SPRING
Rear coil springs are rated separately for each cor-
ner or side of the vehicle depending on optional
equipment and type of vehicle service. If a coil spring
requires replacement, be sure the spring needing
replacement is replaced with a spring meeting the
correct load rating for the vehicle with its specific
options.
KNUCKLE (REAR)
A forged rear knuckle bolts to each rear strut
assembly (Fig. 1). The rear knuckle's spindle sup-
ports the rear hub and bearing. Together they sup-
port the rear tire and wheel. The movement of the
rear knuckle is controlled laterally using two lateral
arms attached to the knuckle. Fore and aft move-
ment of the knuckle is controlled by using a tension
strut.
HUB AND BEARING (REAR)
The hub and bearing is mounted on the rear
knuckle's spindle (Fig. 1). The hub and bearing
adapts the tire and wheel assembly to the knuckle.
It's bearing allows the tire and wheel assembly to
rotate freely on the vehicle.
All vehicles are equipped with permanently lubri-
cated and sealed for life rear wheel bearings. There
is no periodic lubrication or maintenance recom-
mended for these units.
The only servicable components of the hub and
bearing are the wheel mounting studs.
If a vehicle is equipped with antilock brakes, the
tone wheels for the rear wheel speed sensors are
pressed onto the hub.
LATERAL ARMS
The lateral arms control the lateral movement of
the rear suspension, specifically the knuckle (Fig. 1).
There are two lateral arms per side of the rear sus-
pension. One arm is attached to the front end of the
knuckle and the other is attached to the rear of the
knuckle. The other end of each lateral arm attaches
to the rear crossmember.
Visually it appears that the left rear arm is
mounted backwards in relation to the other arms
(Fig. 2). Although the left rear arm looks like it is
same as the right rear arm, just reversed, it is not
the same; the arms are not interchangeable.
The front arms are interchangeable, but should be
mounted with the side displaying the word ªFOR-
WARDº stamped into it toward the front of the vehi-
cle. The trimmed outer edge of the arms will then be
facing the rear of the vehicle.

DESCRIPTION AND OPERATION (Continued)

KNUCKLE (REAR)
The rear knuckle is not a repairable component of
the rear suspension. Upon visual inspection, if it is
determined that the knuckle is cracked, bent or bro-
ken, no attempt is to be made to repair or to
straighten the knuckle. The knuckle must be
replaced if found to be damaged in any way.
HUB AND BEARING (REAR)
The hub and bearing is designed for the life of the
vehicle and requires no type of periodic maintenance
(Fig. 1). 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 condi-
tions 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 thebearing is considered normal and should not require
replacement of the wheel bearing.
To diagnose a bent hub, refer to BRAKE ROTOR in
the DIAGNOSIS AND TESTING section in the
BRAKES service manual group for the procedure on
measuring hub runout.
LATERAL ARMS
Inspect each lateral arm (Fig. 1). Look for signs of
contact with an object that has caused damage to the
lateral arm. If the lateral arm is bent or damaged,
the lateral arm will require replacement. Do not
attempt to repair or straighten a lateral arm.
Inspect the lateral arm isolator bushings and their
sleeves for signs of damage or deterioration. If dam-
age or deterioration is present, replacement of the
entire lateral arm will be required. The isolator
bushings cannot be serviced separately from the lat-
eral arms.
TENSION STRUT
Inspect the tension strut (Fig. 1). Look for signs of
contact with any object that has bent or caused other
damage to the tension strut. If the tension strut is
bent or damaged, the tension strut will require
replacement. Do not attempt to repair or straighten a
tension strut.
Inspect the tension strut front (spool type) bushing,
and rear (bayonet type) bushings and retainers for
signs of deterioration or damage. If the front bushing
is damaged or shows signs of deteriation, the tension
strut must be replaced. The front bushing cannot be
replaced separately. If the rear bushings are deterio-
rated or damaged, or the retainers are damaged,
replacement is necessary. The bushings and retainers
can be replaced separately from the tension strut.
STABILIZER BAR (REAR)
Inspect the stabilizer bar (Fig. 1). Look for damage
or bending. If damage is evident, the bar must be
replaced.
Inspect for broken, cracked or distorted stabilizer
bar cushions and cushion retainers. The horizontal
slit at the front of each cushion is supposed to be
there. If damage is evident, the cushions can be
replaced separately from the stabilizer bar utilizing
the horizontal slit.
Inspect the stabilizer bar links that attach the sta-
bilizer bar to each rear strut. Look for damage or
deterioration of the bushings on the ends of each
link. Inspect the stabilizer bar link to ensure it is not
bent or broken. If any of these conditions are present,
the stabilizer bar link must be replaced. The links
can be replaced separately from the stabilizer bar.

independent rear suspension. Vehicles with inde-
pendent rear suspension can not be hoisted using
equipment designed to lift a vehicle by the rear
axle. If this type of hoisting equipment is used dam-
age to rear suspension components will occur.
NOTE: If a rear suspension component becomes
bent, damaged or fails, no attempt should be made
to straighten or repair it. Always replace it with a
new component.
