INSPECTION - LOWER CONTROL ARM
Inspect lower control arm for signs of damage from
contact with the ground or road debris. If lower con-
trol arm shows any sign of damage, inspect lower
control arm for distortion. Do not attempt to repair
or straighten a broken or bent lower control arm. If
damaged, the lower control arm casting is serviced
only as a complete component.
Inspect both lower control arm isolator bushings
for severe deterioration, and replace as required.
Inspect the rear hydro-bushing for seepage. Both
type rear bushings are serviceable. If the front bush-
ing fails, the lower control arm must be replaced.
Inspect and test the ball joint per the procedure
listed in Lower Ball Joint. (Refer to 2 - SUSPEN-SION/FRONT/LOWER BALL JOINT - DIAGNOSIS
AND TESTING)

REAR SUSPENSION
DESCRIPTION - REAR SUSPENSION
The rear suspension design on this vehicle uses
leaf springs, and a tube and casting axle (Fig. 1) (Fig.
2). The leaf springs used on the rear suspension of
this vehicle are of either a mono-leaf or multi-leaf
design.
There are four different rear suspension designs
available:²Front-Wheel-Drive
²Front-Wheel-Drive with Fold-in-Floor Seating
²All-Wheel-Drive
²Front-Wheel-Drive Commercial
The Front-Wheel-Drive (FWD) rear suspension
uses an axle that is mounted to mono-leaf springs
using isolator bushings at the axle mounting brack-
ets. The stabilizer bar mounts behind the axle.

SHOCK ABSORBER
DESCRIPTION
There is one shock absorber on each side of the
rear suspension. The top of each shock absorber is
bolted to the frame rail. The bottom of each shock
absorber is bolted to the rear axle.
This vehicle is available with either standard type
or load-leveling shock absorbers. On the exterior,
load-leveling shock absorbers are larger in diameter
than standard shock absorbers. The load-leveling
shock absorbers mount the same as the standard
shock absorbers.
OPERATION
The shock absorber dampens jounce and rebound
motions of the spring and suspension.
Each load-leveling shock absorber is a self-leveling,
self-contained vehicle leveling system and shock
absorber combined. It does not require an external
compressor, hoses, or height leveling sensors. All the
height leveling sensors, hydraulic pump, etc., are
contained inside the shock absorber. It uses road
inputs (bumps, stops, starts, turns, acceleration,
deceleration, etc.) to activate pumping, which results
in the extension and compression of the shock
absorber.
REMOVAL - SHOCK ABSORBER
(1) Raise vehicle. (Refer to LUBRICATION &
MAINTENANCE/HOISTING - STANDARD PROCE-
DURE)
(2) Support the rear axle of the vehicle using 2
jackstands positioned at the outer ends of the axle.
NOTE: If the shock absorber lower mounting bolt
deflects upward during removal, raise axle by
adjusting the support jack. If the lower shock
absorber bolt deflects downward during removal,
lower the axle by adjusting the support jack.
(3) Remove the shock absorber lower mounting
bolt.

STABILIZER BAR
DESCRIPTION
Some front-wheel-drive models use a stabilizer bar.
It is mounted behind the rear axle. All-wheel-drive
models use a stabilizer bar that is mounted in front
of the rear axle.
The stabilizer bar interconnects both sides of the
rear axle and attaches to the rear frame rails using 2
rubber isolated link arms.
Both type stabilizer bars have the same basic com-
ponents. Attachment to the rear axle tube, and rear
frame rails is through rubber-isolated bushings.
The 2 rubber isolated links are connected to the
rear frame rails by brackets. These brackets are
bolted to the bottom of the frame rails.
OPERATION
Jounce and rebound movements affecting one
wheel are partially transmitted to the opposite wheel
to reduce body roll.
