Mopar Lock ’N Seal or Loctite
T
242 on existing nut.
(4) Remove hydraulic jack.
(5) Attach brake hose brackets to suspension arm.
(6) Tighten upper suspension arm pivot bolts to
224 N·m (165 ft. lbs.).
(7) Install the wheel and tire assembly. (Refer to
22 - TIRES/WHEELS/WHEELS - STANDARD PRO-
CEDURE).

SHOCK
DESCRIPTION
The top of the low-pressure gas charged shock are
bolted to the frame. The bottom of the shock are
bolted to the lower suspension arm.
OPERATION
The shock absorbers dampen 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 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) Raise and support vehicle.
(2) Remove the upper shock absorber nut, retainer
and grommet (Fig. 13) .
(3) Remove the lower bolt and remove the shock
absorber.

(1) Install the lower retainer (lower retainer is
stamped with a L) and grommet on the shock
absorber stud. Insert the shock absorber through the
frame bracket hole.
(2) Install the lower bolt and tighten the bolt to
108 N·m (80 ft. lbs.).
(3) Install the upper grommet, retainer (upper
retainer is stamped with a U) and new nut or use
Mopar Lock ’N Seal or Loctite
t 242 on existing nut,
on the shock absorber stud. Tighten nut to 26 N·m
(19 ft. lbs.).
TORSION BAR
DESCRIPTION
The front of the bar mounts 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 angle of the torsion bar. Increasing or
decreasing the bar angle changes the angle 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) Turn the adjustment bolt counterclockwise to
release spring load (Fig. 14).
NOTE: Count and record the number of turns for
installation reference.
(3) Remove the adjustment bolt from swivel.
(4) Remove torsion bar and anchor. Remove anchor
from torsion bar.
(5) Remove all foreign material from torsion bar
mounting in anchor and suspension arm.
(6) Inspect adjustment bolt, bearing and swivel for
damage.

(1) Insert torsion bar ends into anchor and suspen-
sion arm.
(2) Position anchor and bearing in frame cross-
member. Install adjustment bolt through bearing,
anchor and into the swivel.
(3) Turn adjustment bolt clockwise the recorded
amount of turns.
(4) Lower vehicle and adjust the front suspension
height. (Refer to 2 - SUSPENSION/WHEEL ALIGN-
MENT - STANDARD PROCEDURE).

REAR
DESCRIPTION
The rear suspension is comprised of:
• Drive Axle
• Shock Absorbers
• Stabilizer Bar (optional)
• Leaf Springs
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 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. This will maintain vehicle
ride comfort and prevent premature bushing wear.

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

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 below for additional infor-
mation.
