DESCRIPTION
The rear suspension (Fig. 1) is comprised of :
²Drive axle
²Shock absorbers
²Coil springs
²Lower suspension arms
²Upper suspension arm
²Stabilizer bar
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.
WARNING
WARNING:: Suspension components with rubber
bushings must be tightened with the vehicle at nor-
mal ride height. It is important to have the springs
supporting the weight of the vehicle when the fas-
teners are torqued. If springs are not at their normal
ride position, vehicle ride comfort will be affected
and cause premature bushing wear.

UPPER CONTROL ARM
DESCRIPTION - UPPER SUSPENSION ARM,
BUSHINGS, AND BALL JOINT
The suspension arm uses vertical spool bushings to
isolate road noise. The suspension arm is bolted
through bushings to cage nuts in the body and a ball
joint to the top of the differential housing.
OPERATION - UPPER SUSPENSION ARM,
BUSHINGS, AND BALL JOINT
The upper suspension arm provides fore/aft and
lateral location of the rear axle. The suspension arm
travel is limited through the use of jounce bumpers
in compression and shock absorbers in rebound.
REMOVAL
(1) Raise and support the vehicle.
(2) Support the rear axle with a hydraulic jack.
(3) Remove the ball joint pinch bolt from the top of
the differential housing bracket (Fig. 7).
(4) Remove partial nuts from the heat shield in
order to lower the shield down enough to get the
proper clearence to remove the right side bolt from
the body.
(5) Remove the upper suspension arm mounting
bolts from the body and remove the arm (Fig. 8).
(6) Remove the support bracket mounting bolts if

(1) Position the vehicle on a level surface perpen-
dicular to a flat wall 7.62 meters (25 feet) away from
the front of the front fog lamp lens (Fig. 16). If nec-
essary, tape a line on the floor 7.62 meters (25 feet)
away from and parallel to the wall.
(2) Measure up on the wall 1.27 meters (5 feet)
from the floor and tape a vertical line on the align-
ment screen at the centerline of the vehicle. Sight
along the centerline of the vehicle (from the rear of
the vehicle forward) to verify the accuracy of the cen-
terline placement.
(3) Rock the vehicle from side-to-side three times
to allow the suspension to stabilize, then jounce the
front suspension three times by pushing downward
on the front bumper and releasing. Measure the dis-
tance from the center of the front fog lamp lens to
the floor. Transfer this measurement to the align-
ment screen and tape a horizontal line on the wall at
this mark. This line will be used for up-and-down
adjustment reference.
(4) Measure the distance from the centerline of the
vehicle to the center of each front fog lamp beingaligned. Transfer these measurements to the align-
ment screen and tape a vertical line this distance to
each side of the vehicle centerline. These lines will be
used for left/right reference.
(5) Rotate the front fog lamp adjusting screws to
adjust the beam height as required (Fig. 17).
FRONT LAMP BULB
REMOVAL
The front lamp unit may contain either one or two
bulbs, depending upon the market for which the
vehicle was manufactured. The service procedures for
one bulb or for both bulbs is the same, only the bulb
sizes and types may differ. Be certain any removed
bulb is replaced with the same bulb size and type
that was removed.
(1) Disconnect and isolate the battery negative
cable.
(2) Remove the front lamp unit from the front
bumper fascia. (Refer to 8 - ELECTRICAL/LAMPS/

below the headlamp horizontal centerline for vehicles
in North America, or from just below horizontal to
125 millimeters (5 inches) below the headlamp hori-
zontal centerline for vehicles in Rest-Of-World.
(4) Repeat the adjustment procedure for the oppo-
site headlamp.
