Hoist Check

Noise:
Noise can be caused by loose suspension or shock absorber attachments. Verify that all attachments for the suspension components are tight. Replace any shock absorbers that have a damaged integral lower mounting bushing. Check front and rear shock absorbers for external damage.
Bottom/Hopping:
Check condition of the rubber suspension travel stops (shock absorber jounce bumper). Replace if worn or missing. Examine for evidence of previous overload which may have damaged components.
Force-Check:
Support front suspension lower arm or rear axle housing and remove lower shock absorber attachment. Stroke shock absorber body using as much travel as possible. The action should be smooth and uniform throughout each stroke. Damping forces should be equivalent on both sides of the vehicle.

NOTE:
Replace only the worn or damaged shock absorber. Shock absorbers do not require replacement in pairs, unless both units are worn or damaged.
