VEHICLE IDENTIFICATION
NUMBER
DESCRIPTION
The Vehicle Identification Number (VIN) plate is
located on the lower windshield fence next to the left
a-pillar. The VIN contains 17 characters that provide
data concerning the vehicle. Refer to the VIN
DECODING INFORMATION table to determine the
identification of a vehicle.To protect the consumer from theft and possible
fraud the manufacturer is required to include a
Check Digit at the ninth position of the Vehicle Iden-
tification Number. The check digit is used by the
manufacturer and government agencies to verify the
authenticity of the vehicle and official documenta-
tion. The formula to use the check digit is not
released to the general public.

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 mounting
bushings 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.

STANDARD PROCEDURE - TOE ADJUSTMENT
CAMBER AND CASTER ARE NOT ADJUSTABLE
(TOE ONLY)..
The wheel toe position adjustment is the final
adjustment.
(1) Start the engine and turn wheels both ways
before straightening the wheels. Secure the steering
wheel with the front wheels in the straight-ahead
position.
(2) Loosen the tie rod jam nuts.
NOTE: Each front wheel should be adjusted for
one-half of the total toe position specification. This
will ensure the steering wheel will be centered
when the wheels are positioned straight-ahead.
(3) Adjust the wheel toe position by turning the
inner tie rod as necessary.
(4) Tighten the tie rod jam nut to 50 N´m (37 ft.
lbs.).
(5) Verify the specifications
(6) Turn off engine.

DRIVELINE VIBRATION
Drive Condition Possible Cause Correction
Propeller Shaft Noise 1) Undercoating or other foreign
material on shaft.1) Clean exterior of shaft and wash
with solvent.
2) Loose U-joint clamp screws. 2) Install new clamps and screws
and tighten to proper torque.
3) Loose or bent U-joint yoke or
excessive runout.3) Install new yoke.
4) Incorrect driveline angularity. 4) Measure and correct driveline
angles.
5) Rear spring center bolt not in
seat.5) Loosen spring u-bolts and seat
center bolt.
6) Worn U-joint bearings. 6) Install new U-joint.
7) Propeller shaft damaged or out
of balance.7) Installl new propeller shaft.
8) Broken rear spring. 8) Install new rear spring.
9) Excessive runout or unbalanced
condition.9) Re-index propeller shaft, test,
and evaluate.
10) Excessive drive pinion gear
shaft runout.10) Re-index propeller shaft and
evaluate.
11) Excessive axle yoke deflection. 11) Inspect and replace yoke if
necessary.
12) Excessive transfer case runout. 12) Inspect and repair as necessary.
Universal Joint Noise 1) Loose U-joint clamp screws. 1) Install new clamps and screws
and tighten to proper torque.
2) Lack of lubrication. 2) Replace as U-joints as
necessary.
PROPELLER SHAFT BALANCE
NOTE: Removing and indexing the propeller shaft
180É relative to the yoke may eliminate some vibra-
tions.
If propeller shaft is suspected of being out of bal-
ance, verify with the following procedure:
(1) Place vehicle in netrual.
(2) Raise and support the vehicle by the axles as
level as possible.
(3) Clean all foreign material from propeller shaft
and universal joints.
(4) Inspect propeller shaft for missing balance
weights, broken welds, and bent areas.
NOTE: If propeller shaft is bent, it must be replaced.
(5) Inspect universal joints for wear, properly
installed and correct alignment with the shaft.
(6) Check universal joint clamp screws torque.
(7) Remove wheels and tires. Install wheel lug
nuts to retain the brake drums/rotors.(8) Mark and number propeller shaft six inches
from the pinion yoke end at four positions 90É apart.
(9) Run and accelerate the vehicle until vibration
occurs. Note intensity and speed the vibration
occurred. Stop the engine.
(10) Install a screw clamp at position 1 (Fig. 1).
(11) Start engine and re-check for vibration. If lit-
tle or no change in vibration is evident, move clamp
to the next positions and repeat vibration test.
NOTE: If there is no difference in vibration at the
other positions, the vibration may not be propeller
shaft.
(12) If vibration decreased, install a second clamp
(Fig. 2) and repeat vibration test.
(13) If additional clamp causes additional vibra-
tion, separate clamps 1/2 inch above and below the
mark. Repeat the vibration test (Fig. 3).
(14) Increase distance between clamps and repeat
test until vibration is at the lowest level. Bend the
slack end of the clamps so the screws will not loosen.
