REAR
DESCRIPTION
The rear suspension is comprised of:
²Shock Absorbers
²Jounce Bumpers
²Stabilizer Bar
²Leaf Springs
²Drive Axle
CAUTION: A vehicle should always be loaded so
the vehicle weight center-line is located immedi-
ately forward of the rear axle. Correct vehicle load-
ing provides proper front tire-to-road contact. This
results in maximum vehicle handling stability and
safety. Incorrect vehicle weight distribution can
cause excessive tire tread wear, spring fatigue or
failure, and erratic steering.
CAUTION: Suspension components with rubber/ure-
thane bushings (except stabilizer bar) should be
tightened with the vehicle at normal ride height. It is
important to have the springs supporting the weight
of the vehicle when the fasteners are torqued. If
springs are not at their normal ride position, vehicle
ride comfort could be affected and premature bush-
ing wear may occur.
DIAGNOSIS AND TESTING - SPRING AND
SHOCK
A knocking or rattling noise from a shock absorber
may be caused by movement between mountingbushings and metal brackets or attaching compo-
nents. These noises can usually be stopped by tight-
ening the attaching nuts. If the noise persists,
inspect for damaged and worn bushings, and attach-
ing components. Repair as necessary if any of these
conditions exist.
A squeaking noise from the shock absorber may be
caused by the hydraulic valving and may be intermit-
tent. This condition is not repairable and the shock
absorber must be replaced.
The shock absorbers are not refillable or adjust-
able. If a malfunction occurs, the shock absorber
must be replaced. To test a shock absorber, hold it in
an upright position and force the piston in and out of
the cylinder four or five times. The action throughout
each stroke should be smooth and even.
The spring eye and shock absorber bushings do not
require any type of lubrication. Do not attempt to
stop spring bushing noise by lubricating them.
Grease and mineral oil-base lubricants will deterio-
rate the bushing rubber.
If the vehicle is used for severe, off-road operation,
the springs should be examined periodically. Check
for broken and shifted leafs, loose and missing clips,
and broken center bolts. Refer to Spring and Shock
Absorber Diagnosis chart for additional information.

WHEEL ALIGNMENT
DESCRIPTION
NOTE: Camber and Caster are not adjustable on
this vehicle. (TOE ONLY).
NOTE: Suspension components with rubber/ure-
thane bushings should be tightened with the vehi-
cle at normal ride height. It is important to have the
springs supporting the weight of the vehicle when
the fasteners are torqued. If springs are not at their
normal ride position, vehicle ride comfort could be
affected and premature bushing wear may occur.
Wheel alignment involves the correct positioning of
the wheels in relation to the vehicle. The positioning
is accomplished through suspension and steering
linkage adjustments. An alignment is considered
essential for efficient steering, good directional stabil-
ity and to minimize tire wear. The most important
measurements of an alignment are caster, camber
and toe (Fig. 1).
CAUTION: Never attempt to modify suspension or
steering components by heating or bending.
DIAGNOSIS AND TESTING - PRE - ALIGNMENT
INSPECTION
Before starting wheel alignment, the following
inspection and necessary corrections must be com-
pleted. Refer to Suspension and Steering System
Diagnosis Chart below for additional information.
(1) Inspect tires for size, air pressure and tread
wear.
(2) Inspect front wheel bearings for wear.
(3) Inspect front wheels for excessive radial or lat-
eral runout and balance.
(4) Inspect ball studs, linkage pivot points and
steering gear for looseness, roughness or binding.
(5) Inspect suspension components for wear and
noise.
(6) Road test the vehicle.
