TORSION BAR
DESCRIPTION
The front of the bar connects to the back side of
the lower suspension arm. The rear end of the bar is
mounted in a anchor that rests in the frame cross-
member.
OPERATION
The torsion bars are used to control ride height
and ride quality. The vehicle height is adjusted
through an anchor adjustment bolt that increases or
decreases the wind up of the torsion bar. Increasing
or decreasing the bar angle changes the wind up of
the suspension arms.
REMOVAL
CAUTION: The left and right side torsion bars are
NOT interchangeable. The bars are identified and
stamped R or L, for right or left. The bars do not
have a front or rear end and can be installed with
either end facing forward.
(1) Raise and support the vehicle with the front
suspension hanging.
(2) Remove the transfer case skid plate (Refer to
13 - FRAME & BUMPERS/FRAME/TRANSFER
CASE SKID PLATE - REMOVAL).
NOTE: Count and record the number of turns for
installation reference.
(3) Mark the adjustment bolt setting.
(4) Install Special Tool - 8686 to the anchor arm
and the cross member (Fig. 30).(5) Increase the tension on the anchor arm tool
until the load is removed from the adjustment bolt
and the adjuster nut (Fig. 30).
(6) Turn the adjustment bolt counterclockwise to
remove the bolt and the adjuster nut..
(7) Remove the Special Tool - 8686, allowing the
torsion bar to unload (Fig. 30).
(8) Remove torsion bar and anchor. Remove anchor
from torsion bar (Fig. 31).
(9) Remove all foreign material from torsion bar
mounting in anchor and suspension arm.
(10) Inspect adjustment bolt, bearing and swivel
for damage.

UPPER BALL JOINT
DIAGNOSIS AND TESTING - UPPER BALL
JOINT
NOTE: If the ball joint is equipped with a lubrication
fitting, grease the joint then road test the vehicle
before performing test.
(1) Raise the front of the vehicle. Place safety floor
stands under both lower control arms as far outboard
as possible. Lower the vehicle to allow the stands to
support some or all of the vehicle weight.
(2) Remove the front tires.(3) Mount a dial indicator solidly to the frame and
then zero the dial indicator.
(4) Position dial indicator plunger on the topside of
the upper ball joint (Fig. 32).
NOTE: The dial indicator plunger must be perpen-
dicular to the machined surface of the ball joint
(Fig. 32).
NOTE: Use care not to pry or tear the ball joint
boot, when checking the free play.
(5) Position a pry bar between the steering
knuckle and the upper control arm. Pry upwards on
the upper control arm (Fig. 32).
(6) If the travel exceeds 0.5 mm (0.020 in.), replace
the upper control arm since the upper ball joint is
integral to the arm (Refer to 2 - SUSPENSION/
FRONT/UPPER CONTROL ARM - REMOVAL).
(7) If the upper ball joint is within specs reinstall
the front tires (Refer to 22 - TIRES/WHEELS/
WHEELS - STANDARD PROCEDURE).

SHOCK
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 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 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. 23).
(3) Remove the lower bolt from the axle bracket
(Fig. 24). Remove the shock absorber from engine
compartment.
INSTALLATION
(1) Position the lower retainer and grommet on the
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.).
(4) Install upper grommet and retainer. Install
upper shock nut and tighten to 54 N´m (40 ft. lbs).

REAR
DESCRIPTION
The rear suspension is comprised of:
²Shock Absorbers
²Jounce Bumpers
²Leaf Springs
²Auxiliary Leaf Spring (3500 series)
²Auxiliary Spring Bumpers (3500 series)
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.

to 135 N.m (100 ft. lbs.)
(4) Remove the support and lower the vehicle.
SPRING
DESCRIPTION
The rear suspension system uses a multi-leaf
springs and a solid drive axle. The forward end of the
springs are mounted to the body rail hangers
through rubber bushings. The rearward end of the
springs are attached to the body by the use of shack-
les. The spring and shackles use rubber bushings.
OPERATION
The springs control ride quality and maintain vehi-
cle ride height. The shackles allow the springs to
change their length as the vehicle moves over various
road conditions.

and install the bolt and nut.
(4) Tighten the spring front and rear eye pivot bolt
snug do not torque.
(5) Install the spring clamp bolts, plate and the
retaining nuts.
(6) Remove the holding fixture for the rear axle.
