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 vehicle.
(2) Remove shock upper nut and remove retainer
and grommet.
(3) Remove lower mounting bolt from suspension
arm and remove shock (Fig. 5).
INSTALLATION
(1) Extend shock fully, install retainer and grom-
met on top of shock absorber. Check grommets and
retainer for wear.(2) Guide shock up through upper suspension arm
bracket. Install top grommet, retainer and nut.
Tighten nut to 54 N´m (40 ft. lbs.).
(3) Align bottom end of shock into lower suspen-
sion arm and install mounting bolt. Tighten bolt to
142 N´m (105 ft. lbs.).
(4) Remove support and lower vehicle.
SPRING
REMOVAL
(1) Raise and support the vehicle.
(2) Remove the tire and wheel assembly.
(3) Remove the brake caliper assembly and rotor,
(Refer to 5 - BRAKES/HYDRAULIC/MECHANICAL/
ROTORS - REMOVAL).
(4) Remove the cotter pin and nut from the tie rod.
Remove the tie rod end from the steering knuckle
with Puller C-3894-A.
(5) Remove the stabilizer bar link from the lower
suspension arm.
(6) Support the lower suspension arm outboard
end with a jack. Place a jack under the arm in front
of the shock mount.
(7) Remove the cotter pin and nut from the lower
ball joint. Separate the ball joint with Remover
C-4150A.
(8) Remove the lower shock bolt from the suspen-
sion arm.
(9) Lower the jack and suspension arm until
spring tension is relieved. Remove spring and rubber
isolator (Fig. 6).
