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) Remove the nut, retainer and grommet from
the upper stud in the engine compartment.
(2) Remove three nuts from the upper shock
bracket (Fig. 18).
(3) Remove the lower bolt from the axle bracket
(Fig. 19). Remove the shock absorber from engine
compartment.
INSTALLATION
(1) Position the lower retainer and grommet on the
upper stud. Insert the shock absorber through the
spring from engine compartment.
(2) Install the lower bolt and tighten to 135 N·m
(100 ft. lbs.).
(3) Install the upper shock bracket and three nuts.
Tighten nuts to 75 N·m (55 ft. lbs.).
(4) Install upper grommet and retainer. Install
upper shock nut and tighten to 47 N·m (35 ft. lbs).
