Suspension Strut / Shock Absorber: Testing and Inspection
Rear Spring And Shock
SPRING AND SHOCK
A knocking or rattling noise from a shock absorber may be caused by movement between mounting bushings and metal brackets or attaching
components. These noises can usually be stopped by tightening the attaching nuts. If the noise persists, inspect for damaged and worn bushings, and
attaching 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 intermittent. This condition is not repairable and the
shock absorber must be replaced.
The shock absorbers are not refillable or adjustable. 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.
If the vehicle is used for severe, off-road operation, the springs should be examined periodically. Check for broken colis. Refer to Spring and Shock
Absorber Diagnosis chart for additional information.
