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.

ing bracket.
(3) Install the ball joint pinch bolt and tighten to
95 N´m (70 ft. lbs.). (Fig. 7).

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
needed. (Fig. 9)

N´m (74 ft. lbs.).
(3) Retighten the heat shield back into place.
(4) Pull the arm down on the differential housing
bracket and install the pinch bolt and nut. Tighten
the nut to 95 N´m (70 ft. lbs.) (Fig. 7).

LOWER CONTROL ARM
DESCRIPTION
The lower suspension arms are stamped steel and
welded and use voided round bushings at the axle
end and solid rubber at the body end of the arm.
OPERATION
The bushings provide isolation from the axle. The
arms mount to the unibody frame rail bracket and
the axle brackets. The arm and bushings provide
location and react to loads.
REMOVAL
(1) Raise the vehicle and support the rear axle.
(2) Remove the stabilizer bar retaining bolts from
the suspension arm.
(3) Remove the lower suspension arm nut and bolt
from the axle bracket (Fig. 10).
NOTE: When removing the right side suspension
arm from the frame rail it will be necessary to pry
the exhaust over slightly to allow enough clearance
to remove the bolt.
(4) Remove the nut and bolt (Fig. 10) from the
frame rail and remove the lower suspension arm.
INSTALLATION
(1) Position the lower suspension arm in the axle
bracket and frame rail bracket.NOTE: The end of the arm with the voided round
bushing attaches to the axle bracket.
(2) Install the axle bracket bolt and nut finger
tight (Fig. 10).
NOTE: When installing the right side suspension
arm to the frame rail it will be necessary to pry the
exhaust over slightly to allow enough clearance to
install the bolt.
(3) Install the frame rail bracket bolt and nut fin-
ger tight.
(4) Install the stabilizer bar retaining bolts to the
suspension arm.
(5) Remove the supports and lower the vehicle.
(6) With the vehicle on the ground tighten the nut
at the frame to 163 N´m (120 ft. lbs.). Tighten the
nut at the axle bracket to 163 N´m (120 ft. lbs.).
