SHOCK ABSORBER
DESCRIPTION
There is one shock absorber on each side of the
rear suspension. The top of each shock absorber is
bolted to the frame rail. The bottom of each shock
absorber is bolted to the rear axle.
This vehicle is available with either standard type
or load-leveling shock absorbers. On the exterior,
load-leveling shock absorbers are larger in diameter
than standard shock absorbers. The load-leveling
shock absorbers mount the same as the standard
shock absorbers.
OPERATION
The shock absorber dampens jounce and rebound
motions of the spring and suspension.
Each load-leveling shock absorber is a self-leveling,
self-contained vehicle leveling system and shock
absorber combined. It does not require an external
compressor, hoses, or height leveling sensors. All the
height leveling sensors, hydraulic pump, etc., are
contained inside the shock absorber. It uses road
inputs (bumps, stops, starts, turns, acceleration,
deceleration, etc.) to activate pumping, which results
in the extension and compression of the shock
absorber.
REMOVAL - SHOCK ABSORBER
(1) Raise vehicle. (Refer to LUBRICATION &
MAINTENANCE/HOISTING - STANDARD PROCE-
DURE)
(2) Support the rear axle of the vehicle using 2
jackstands positioned at the outer ends of the axle.
NOTE: If the shock absorber lower mounting bolt
deflects upward during removal, raise axle by
adjusting the support jack. If the lower shock
absorber bolt deflects downward during removal,
lower the axle by adjusting the support jack.
(3) Remove the shock absorber lower mounting
bolt.

STABILIZER BAR
DESCRIPTION
Some front-wheel-drive models use a stabilizer bar.
It is mounted behind the rear axle. All-wheel-drive
models use a stabilizer bar that is mounted in front
of the rear axle.
The stabilizer bar interconnects both sides of the
rear axle and attaches to the rear frame rails using 2
rubber isolated link arms.
Both type stabilizer bars have the same basic com-
ponents. Attachment to the rear axle tube, and rear
frame rails is through rubber-isolated bushings.
The 2 rubber isolated links are connected to the
rear frame rails by brackets. These brackets are
bolted to the bottom of the frame rails.
OPERATION
Jounce and rebound movements affecting one
wheel are partially transmitted to the opposite wheel
to reduce body roll.

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 +0.3É and the right
camber is 0.0É, the cross camber would be +0.3É.
CASTER
Caster is the forward or rearward tilt of the steer-
ing 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).
²Forward tilt (upper ball joint ahead of lower)
results in a negative caster angle.
²Rearward 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.
CROSS CASTER
Cross caster is the difference between left and
right caster.
TOE
Toe is the inward or outward angle of the wheels
as viewed from above the vehicle (Fig. 3).
²Toe-in is produced when the front edges of the
wheels on the same axle are closer together than the
rear edges.
²Toe-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 mea-
surement 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.

Page 91 of 2339

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).
²Negative thrust angle means the rear tires are
tracking to the left of the front tires.
²Positive 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.

NOTE: Prior to reading the vehicle's alignment
readouts, the front and rear of vehicle should be
jounced. Induce jounce (rear first, then front) by
grasping the center of the bumper and jouncing
each end of vehicle an equal number of times. The
bumper should always be released when vehicle is
at the bottom of the jounce cycle.
(3) Read the vehicle's current front and rear align-
ment settings. Compare the vehicle's current align-
ment settings to the vehicle specifications for camber,
caster and toe-in. (Refer to 2 - SUSPENSION/
WHEEL ALIGNMENT - SPECIFICATIONS)
(4) If front camber and caster are not within spec-
ifications, proceed to CAMBER AND CASTER below.
If caster and camber are within specifications, pro-
ceed to TOE which can be found following CAMBER
AND CASTER. Rear camber, caster and toe are not
adjustable. If found not to be within specifications,
reinspect for damaged suspension or body compo-
nents and replace as necessary.
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 align-
ment, caster and camber are not normally considered
adjustable angles. Camber and caster should be
checked to ensure they meet vehicle specifications.
If front camber is found not to meet alignment
specifications, it can be adjusted using an available
camber adjustment bolt package. Before installing a
camber adjustment bolt package on a vehicle found
to be outside the specifications, inspect the suspen-
sion components for any signs of damage or bending.
CAUTION: Do not attempt to adjust the vehicles
wheel alignment by heating, bending or by perform-
ing any other modification to the vehicle's front
suspension components or body.
If camber readings are not within specifications,
use the following procedure to install the front cam-
ber adjustment bolt package and then adjust front
camber.
CAMBER ADJUSTMENT BOLT PACKAGE INSTALLATION
The camber adjustment bolt package contains 2
flange bolts, 2 cam bolts, 2 dog bone washers, and 4
nuts. This package services both sides of the vehicle.
Use the package to attach the strut clevis bracket to
the steering knuckle after the strut clevis brackethas been modified. To install and adjust the camber
adjustment bolt package, follow the procedure below.
(1) Raise the vehicle until its tires are not support-
ing the weight of the vehicle.
(2) Remove the front tire and wheel assemblies.
CAUTION: When removing the steering knuckle
from the strut clevis bracket, do not put a strain on
the brake flex hose. Also, do not let the weight of
the steering knuckle assembly be supported by the
brake flex hose when removed from the strut
assembly. If necessary use a wire hanger to sup-
port the steering knuckle assembly or if required
remove the brake flex hose from the caliper assem-
bly.
CAUTION: The knuckle to strut assembly attaching
bolt shanks are serrated and must not be turned
during removal. Remove the nuts while holding the
bolts stationary.
(3) Remove the top and bottom, strut clevis
bracket to steering knuckle attaching bolts (Fig.
7)and discard. Separate the steering knuckle from
the strut clevis bracket and position steering knuckle
so it is out of the way of the strut.
CAUTION: When slotting the bottom mounting hole
on the strut clevis bracket, do not enlarge the hole
beyond the indentations on the sides of the strut
clevis bracket (Fig. 8).

(9) Position sealing boot into the tripod housing
retaining groove. Install seal boot retaining clamp
evenly on sealing boot.
(10) Position trilobal boot to interface with the tri-
pod housing. The lobes of the boot must be properly
aligned with the recess's of the tripod housing.
CAUTION: The following positioning procedure deter-
mines the correct air pressure inside the inner CV
joint assembly prior to clamping the sealing boot to
inner CV joint housing. If this procedure is not done
prior to clamping sealing boot to CV joint housing
sealing boot durability can be adversely affected.
CAUTION: When venting the inner CV joint assembly,
use care so that the inner CV sealing boot does not
get punctured, or in any other way damaged. If sealing
boot is punctured, or damaged in any way while being
vented, the sealing boot can not be used.
(11) Insert a trim stick between the CV joint hous-
ing and the sealing boot insert to vent inner CV joint
assembly (Fig. 22).When inserting trim stick
between tripod housing and sealing boot
ensure trim stick is held flat and firmly against
the tripod housing. If this is not done damage
to the sealing boot can occur.
(12)
With trim stick inserted between sealing boot
insert and the CV joint housing, position the intercon-
necting shaft so it is at the center of its travel in the
tripod joint housing. Remove the trim stick from
between the sealing boot insert and the CV joint hous-
ing.This procedure will equalize the air pressurein the CV joint, preventing premature sealing
boot failure.
(13) Clamp CV joint sealing boot to CV joint, using
required procedure for type of boot clamp application.
CRIMP TYPE BOOT CLAMP
If seal boot uses crimp type boot clamp, use the fol-
lowing procedure to install the retaining clamp.
(1) Place crimping tool C-4975-A over bridge of
clamp (Fig. 23).
(2) Tighten nut on crimping tool C-4975-A until
jaws on tool are closed completely together, face to
face (Fig. 24).

BRAKES - BASE
DESCRIPTION
DESCRIPTION - BASE BRAKES
The base brake system consists of the following
components:
²Brake pedal
²Power brake booster
²Master cylinder
²Brake tubes and hoses
²Proportioning valve (non-ABS vehicles only)
²Disc brakes
²Drum brakes
²Brake lamp switch
²Brake fluid level switch
²Parking brakes
Front disc brakes control the braking of the front
wheels; rear braking is controlled by rear drum
brakes or rear disc brakes depending on options.
The hydraulic brake system is diagonally split on
both the non-antilock braking systems and antilock
braking systems. That means the left front and right
rear brakes are on one hydraulic circuit and the right
front and left rear are on the other.
For information on the brake lamp switch, (Refer
to 8 - ELECTRICAL/LAMPS/LIGHTING - EXTERI-
OR/BRAKE LAMP SWITCH - DESCRIPTION)Vehicles equipped with the optional antilock brake
system (ABS) use a system designated Mark 20e. It
is available with or without traction control. This
system shares most base brake hardware used on
vehicles without ABS. ABS components are described
in detail in ANTILOCK BRAKE SYSTEM.DESCRIPTION - BASE BRAKES (EXPORT)
Four-Wheel Disc Antilock Brakes are standard on
all models.
OPERATION - BASE BRAKES
When a vehicle needs to be stopped, the driver
applies the brake pedal. The brake pedal pushes the
input rod of the power brake booster into the booster.
The booster uses vacuum to ease pedal effort as force
is transferred through the booster to the master cyl-
inder. The booster's output rod pushes in the master
cylinder's primary and secondary pistons applying
hydraulic pressure through the chassis brake tubes
to the brakes at each tire and wheel assembly.
The parking brakes are foot-operated. When
applied, the parking brake lever pulls on cables that
actuate brake shoes at each rear wheel. These shoes
come in contact with a hub mounted drum (drum for
disc/drum brakes or drum-in-hat for disc/disc brakes)
and hold it in place.
