Shock diagnosis

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.

The shock absorber bushings do not require any type of lubrication. Do not attempt to stop bushing noise by lubricating them. Grease and mineral oilbase lubricants will deteriorate the bushing.
