LOWER BALL JOINT
DIAGNOSIS AND TESTING - LOWER BALL
JOINT
(1) Raise the front of the vehicle. Place safety floor
stands under both lower suspension arms as far out-
board as possible. Lower the vehicle to allow the
stands to support some or all of the vehicle weight.
NOTE: The upper suspension arms must not con-
tact the rebound bumpers.
(2) Remove the tire and wheel assemblies.
(3) Mount a dial indicator solidly under the lower
suspension arm.
(4) Position indicator plunger against the bottom
of the steering knuckle lower ball joint boss.
NOTE: The dial indicator plunger must be perpen-
dicular to the machined surface of the steering
knuckle lower ball joint boss (Fig. 6).
(5) Position a pry bar over the top of the upper
suspension arm and under the pivot bar of the upper
suspension arm. Pry down on the upper suspension
arm and then zero the dial indicator.
(6) Reposition the pry bar under the upper suspen-
sion arm and on top of the frame rail. Pry up on the
upper suspension arm and record the dial indicator
reading.
(7) If the travel exceeds 1.52 mm (0.060 in.),
replace the lower suspension arm.

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) Remove the upper shock nut, retainer and
grommet from the shock absorber stud (Fig. 8) .
(2) Raise and support the vehicle.
(3) Remove the lower mounting bolts and remove
shock absorber through the lower suspension arm
(Fig. 8) .
INSTALLATION
NOTE: Upper shock nut must be replaced or use
Mopar Lock ’N Seal or Loctite
T
242 on existing nut.
(1) Install the lower retainer (lower retainer is
stamped with a L) and grommet on the shock
absorber stud and extend the shock. Insert the shock
absorber through the lower suspension arm and
upper mounting hole.

(2) Install the lower mounting bolts and tighten to
28 N·m (21 ft. lbs.).
(3) Remove support and lower the vehicle.
(4) Install the upper grommet and retainer (upper
retainer is stamped with a U) on the shock
absorber stud. Install a new nut or use Mopar Lock
’N Seal or Loctite
t 242 on existing nut and tighten to
26 N·m (19 ft. lbs.).
SPRING
DESCRIPTION
The springs mount between the lower suspension
arms and frame rail spring seats. A rubber isolator
seats on top off the spring to help prevent noise.
OPERATION
The coil springs control ride quality and maintain
proper ride height.
REMOVAL
(1) Raise and support the vehicle.
(2) Remove wheel and tire assembly.
(3) Remove the stabilizer bar link from the lower
suspension arm. (Refer to 2 - SUSPENSION/FRONT/
STABILIZER BAR - REMOVAL).
(4) Remove the shock absorber. (Refer to 2 - SUS-
PENSION/FRONT/SHOCK - REMOVAL).
(5) Install Spring Compressor DD-1278 up through
the lower suspension arm, coil spring and upper
shock mounting hole (Fig. 9).
(6) Tighten the tool lower nut to compress the coil
spring.
(7) Remove the lower ball joint nut and separate
the ball joint from the knuckle with Remover
C-4150A (Fig. 10).
(8) Loosen the spring compressor lower nut to
relieve spring tension.
(9) Remove the tool and pull down on the lower
suspension arm to remove the spring.
INSTALLATION
NOTE: The ramped or open end of the coil spring is
the bottom of the spring.
(1) Tape the isolator pad to the top of the coil
spring. Position the spring in the lower suspension
arm pocket. Be sure that the coil spring is seated in
the pocket.
(2) Install Spring Compressor DD-1278 up through
the lower suspension arm, coil spring upper shock
mounting hole.
(3) Tighten the tool nut to compress the coil
spring.

STABILIZER BAR
DESCRIPTION
The bar extends across the front underside of the
chassis and mounts on the frame rails. Links con-
nected the bar to the lower suspension arms. Stabi-
lizer bar mounts are isolated by rubber bushings.
Links are isolated with rubber grommets.
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) Remove the upper link nut, retainer and grom-
met from each link.
(3) Remove the lower link nut from the lower sus-
pension arm on each side (Fig. 11).
(4) Remove the stabilizer bar retainer bolts and
remove the retainers and stabilizer bar from the
vehicle.
(5) Remove the bushings from the stabilizer bar.
INSTALLATION
(1) Install the bushings on the stabilizer bar.
(2) Install the stabilizer bar on the frame and
install the retainers and the bolts.
(3) Tighten the bolts to 60 N·m (45 ft. lbs.).
NOTE: Ensure the bar is center with equal spacing
on both sides.
(4) Install the link lower retainer and grommet on
the links.
(5) Install the links into the stabilizer bar and
lower suspension arm on each side.
(6) Install the lower link mounting nut and tighten
to 47 N·m (35 ft. lbs.).
NOTE: Ensure both link end caps are facing
straight forward.
(7) Install the upper link grommet, retainer and
nut and tighten to 37 N·m (27 ft. lbs.).
(8) Remove support and lower vehicle.
UPPER BALL JOINT
DIAGNOSIS AND TESTING - UPPER BALL
JOINT
(1) Position a floor jack under the lower suspen-
sion arm. Raise the wheel and allow the tire to
lightly contact the floor (vehicle weight relieved from
the tire).
(2) Mount a dial indicator solidly on the upper sus-
pension arm.
(3)
Position the indicator plunger against the
upper ball joint boss of the steering knuckle.
(4) Grasp the top of the tire and apply force in and
out. Look for movement at the ball joint between the
upper suspension arm and steering knuckle.
(5) If lateral movement is greater than 1.52 mm
(0.060 in.), replace upper suspension arm.
