JOUNCE BUMPER
DESCRIPTION
There are two jounce bumpers used in the rear
suspension. One mounts to each frame rail above the
rear axle.

The jounce bumper limits suspension travel and
metal-to-metal contact of the rear axle with the
frame under full jounce conditions.
REMOVAL

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.
(4) While holding shock absorber, remove the
shock absorber upper mounting bolt and shock
absorber.
DISASSEMBLY - SHOCK ABSORBER (UPPER
BUSHING)
NOTE: This procedure applies to load-leveling
shock absorbers only.
(1) Remove the shock absorber from the vehicle.
(2) Install the Receiver, Special Tool 8526-1, into
the cup of the Ball Joint Press, Special Tool C-4212F,and tighten the set screw. Install the Driver, Special
Tool 8526-2, on the tip of the Ball Joint Press screw
drive as shown (Fig. 22).
NOTE: It works well to place the Ball Joint Press,
Special Tool C-4212F, in a bench vise as shown
(Fig. 22) to perform this procedure.
(3) Place the shock absorber upper mounting eye
in the Receiver so the notch in the Receiver clears
the shock absorber body (Fig. 23).
(4) Tighten the screw drive until the Driver con-
tacts the outer circumference of the bushing evenly
(Fig. 23). Continue to tighten the screw drive until
the bushing is pressed completely out of the shock
absorber eye and into the Receiver.
(5) Back off the screw drive and remove the bush-
ing from the Receiver.

the cup of the Ball Joint Press, Special Tool C-4212F,
and tighten the set screw. Install the Driver, Special
Tool 8526-2, on the tip of the Ball Joint Press screw
drive as shown (Fig. 24). Position the Driver this way
to seat the bushing to its correct depth.
(2) Place the shock absorber upper mounting eye
in the Receiver so the notch in the Receiver clears
the shock absorber body (Fig. 25).(3) Position the bushing between the shock
absorber eye and the Driver (Fig. 25). Tighten the
screw drive until the Driver, bushing, and shock
absorber eye are touching and squarely aligned.
(4) Press the bushing into the shock absorber eye
until the Driver bottoms against the face of the eye.
(5) Back off the Ball Joint Press screw drive and
remove the shock absorber from the press.
(6) Install the shock absorber on the vehicle. Refer
to REMOVAL AND INSTALLATION in this section
for the procedure.
INSTALLATION - SHOCK ABSORBER

(c) Raise the vehicle to a comfortable working
level.
(2) Position an under-hoist utility jack or transmis-
sion jack under rear axle toward the side needing
spring replacement. Jack pad should just contact
axle.
NOTE: If shock absorber bolt deflects upward dur-
ing removal, raise axle by adjusting support jack. If
shock absorber bolt deflects downward during
removal, lower axle by adjusting support jack (or by
pulling on axle).
(3) Begin removal of the shock absorber lower
mounting bolt (Fig. 27).
(4) Using 2 jack stands positioned under the outer
ends of the axle, raise the axle enough to remove the
weight of the axle from the rear springs.
(5) Loosen and remove the axle plate bolts from
the rear axle (Fig. 28).
