SHOCK
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) Raise and support the vehicle.
(2) Remove the shock absorber bolt from the rear
axle (Fig. 1).
(3) Unsnap the clip for the ALB lever (left hand
side) (Fig. 1).
(4) Remove the ALB lever from the upper shock
bolt/stud (Fig. 1).
(5) Remove the shock absorber bolt from the frame
side (Fig. 1).
(6) Remove the shock absorber (Fig. 1).
INSTALLATION
(1) Install the shock absorber (Fig. 1).
(2) Install the shock absorber bolt to the frame
side (Fig. 1) Tighten to 80 N·m (59 ft.lbs.) for (SRW)
or Tighten to 140 N·m (103 ft.lbs.) for (DRW).
(3) Install the ALB lever to the upper shock bolt/
stud (left hand side only) (Fig. 1).
(4) Snap the clip for the ALB lever (Fig. 1).
(5) Install the shock absorber bolt to the rear axle
(Fig. 1) Tighten to 70 N·m (52 ft.lbs.) for (M12X1.5
bolt) or Tighten to 110 N·m (81 ft.lbs.) for (M14X1.5
bolt).
(6) Lower the vehicle.

SPRING
DESCRIPTION
The rear suspension system uses a multi-leaf
springs and a solid drive axle. The forward end of the
springs are mounted to the body rail hangers
through rubber bushings. The rearward end of the
springs are attached to the body by the use of shack-
les. The spring and shackles use rubber bushings.
OPERATION
The springs control ride quality and maintain vehi-
cle ride height. The shackles allow the springs to
change their length as the vehicle moves over various
road conditions.

(2) Support the rear axle.
(3) Remove the U-bolt and spring plate (Fig. 2).
(4) Remove the spring from the front spring
bracket (Fig. 2).
(5) Remove the rear spring with the spring shackle
from the spring bracket (Fig. 2).
(6) Lower the rear axle and remove the rear
spring.
(7) Remove the spring shackle from the spring (if
needed) (Fig. 2).
REMOVAL - (DRW)
(1) Raise and support the vehicle.
(2) Support the rear axle.
(3) Remove the U-bolt and spring plate (Fig. 3).
(4) Remove the spring from the front spring
bracket (Fig. 3).
(5) Remove the rear spring with the spring shackle
from the spring bracket (Fig. 3).
(6) Lower the rear axle and remove the rear
spring.
(7) Remove the spring shackle from the spring (if
needed) (Fig. 3).
INSTALLATION
INSTALLATION - (SRW)
NOTE: Larger spring bushing goes toward the front.
