SHOCK
DESCRIPTION
The shocks are mounted inside the springs and
attached at the top to brackets with grommets. These
brackets are bolted on the frame with three studs on
a ring. The shock is mounted at the bottom of the
axle below the spring seat.
OPERATION
The shock absorbers dampen the jounce and
rebound of the vehicle over various road conditions.
DIAGNOSIS AND TESTING - 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 absorbermust 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 shock absorber bushings do not require any
type of lubrication. Do not attempt to stop bushing
noise by lubricating them. Grease and mineral oil-
base lubricants will deteriorate the bushing.
REMOVAL
(1) Remove the nut, retainer and grommet from
the upper stud in the engine compartment.
(2) Remove three nuts from the upper shock
bracket (Fig. 16) .
(3) Remove the lower bolt from the axle bracket
(Fig. 17) . Remove the shock absorber from engine
compartment.
INSTALLATION

upper stud. Insert the shock absorber through the
spring from engine compartment.
(2) Install the lower bolt and tighten to 135 N´m
(100 ft. lbs.).
(3) Install the upper shock bracket and three nuts.
Tighten nuts to 75 N´m (55 ft. lbs.).

SPRING
DESCRIPTION
The springs use a rubber isolators between the
frame bracket and spring. The isolators help prevent
road noise. The bottom of the spring sits on a seat
mounted to the axle.
OPERATION
The coil springs control ride quality and maintain
proper ride height.
REMOVAL
(1) Raise and support the vehicle. Position a
hydraulic jack under the axle to support it.
(2) Paint or scribe alignment marks on lower sus-
pension arm cam adjusters and axle bracket for
installation reference.
(3) Remove the upper suspension arm and loosen
lower suspension arm bolts.
(4) Mark and disconnect the front propeller shaft
from the axle 4x4 models.
(5) Disconnect the track bar from the frame rail
bracket.
(6) Disconnect the drag link from pitman arm.
(7) Disconnect the stabilizer bar link and shock
absorber from the axle.(8) Lower the axle until the spring is free from the
upper mount. Remove the coil spring.
INSTALLATION
(1) Position the coil spring on the axle pad.
(2) Raise the axle into position until the spring
seats in the upper mount.
(3) Connect the stabilizer bar links and shock
absorbers to the axle bracket. Connect the track bar
to the frame rail bracket.
(4) Install the upper suspension arm.
(5) Install the front propeller shaft to the axle 4x4
model.
(6) Install drag link to pitman arm and tighten
nut to specifications. Install new cotter pin.
(7) Remove the supports and lower the vehicle.

to specifications:
²Link to stabilizer bar nut.
²Lower shock bolt.
²Track bar bolt at axle shaft tube bracket.
²Upper suspension arm nut at axle bracket.
²Upper suspension nut at frame bracket.
²Align lower suspension arm reference marks and
tighten cam nut.
²Lower suspension nut at frame bracket.
STABILIZER BAR
DESCRIPTION
The stabilizer bar extends across the front under-
side of the chassis and connects to the frame rails.
Links are connected from the bar to the axle brack-
ets. Stabilizer bar mounts are isolated by teflon lined
rubber bushings.
OPERATION
The stabilizer bar is used to minimize vehicle front
sway during turns. The spring steel bar helps to con-
trol the vehicle body in relationship to the suspen-
sion.
REMOVAL
(1) Raise and support the vehicle.
(2) Hold the stabilizer link shafts with a wrench
and remove the link nuts at the stabilizer bar.
(3) Remove the retainers and grommets from the
stabilizer bar links.
(4) Remove the stabilizer bar link nuts from the
axle brackets.
(5) Remove the links from the axle brackets with
Puller C-3894-A (Fig. 18).
(6) Remove the stabilizer bar clamps from the
frame rails and remove the stabilizer bar.

REAR
DESCRIPTION
The rear suspension is comprised of:
²Shock Absorbers
²Jounce Bumpers
²Stabilizer Bar (optional)
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.
