REAR SUSPENSION
SHOCK ASSEMBLY
DESCRIPTION - SHOCK ASSEMBLY
The rear shock absorber assemblies support the
weight of the vehicle using coil springs positioned
around the shock absorbers. The coil springs are con-
tained between the upper mount of the shock
absorber and a lower spring seat on the body of the
shock absorber.
The top of each shock absorber assembly is bolted
to the top of the inner fender through a microcellular
urethane isolated mount.
The bottom of the shock absorber assembly
attaches to the rear knuckle using a thru-bolt.
The rear coil springs are rated separately for each
corner or side of the vehicle depending on optional
equipment and type of vehicle service. Coil springs
come in a various rates; be sure the correct spring is
in use.
The components of the shock assembly listed below
are serviceable:
• Shock rod nut
• Shock mount
• Shock rod bushings
• Upper spring isolator
• Dust shield
• Cup
• Jounce bumper
• Lower spring isolator
• Coil spring
• Strut
OPERATION - SHOCK ASSEMBLY
The shock absorber assembly cushions the ride of
the vehicle, controlling vibration, jounce and rebound
of the suspension.
The coil spring controls ride quality and maintains
ride height.
The jounce bumper limits suspension travel and
metal-to-metal contact under full jounce.
The shock absorber dampens jounce and rebound
motions of the coil spring and suspension.
DIAGNOSIS AND TESTING - SHOCK ASSEMBLY
(1) Inspect for damaged or broken coil springs.
(2) Inspect for torn or damaged shock absorber
dust shield.
(3) Inspect for damaged lower spring isolator.
(4) Lift dust boot and inspect shock absorber for
evidence of fluid running from the upper end of fluid
reservoir. (Actual leakage will be a stream of fluid
running down the side and dripping off lower end of
unit). A slight amount of seepage between the shock
absorber rod and shock absorber rod seal is not
unusual and does not affect performance of the shock
absorber. Also inspect jounce bumpers for signs of
damage or deterioration.
REMOVAL - SHOCK ASSEMBLY
NOTE: Access for the nuts attaching the rear shock
assembly upper mount to the vehicle is through the
inside of the trunk.
(1) Roll back carpeting on top of the rear shock
tower to access shock mounting nuts.
(2) Remove plastic cover from the top of the shock
assembly.
(3) Remove 2 nuts attaching the shock assembly
upper mount/spring seat to the shock tower.
(4) Raise vehicle on jackstands or centered on a
frame contact type hoist. (Refer to LUBRICATION &
MAINTENANCE/HOISTING - STANDARD PROCE-
DURE)
(5) Remove the rear wheel and tire assembly from
the vehicle.
(6) Remove two fasteners holding the splash shield
to the shock assembly upper mount.
(7) Remove bolt attaching shock absorber to rear
knuckle (Fig. 15).

(8) Remove the shock absorber from the rear
knuckle first when removing the shock absorber from
vehicle by pushing down on the rear suspension.
(9) Move shock assembly downward and tilt top of
shock outward, then remove shock assembly from
vehicle through top of wheel opening.
