Important: The single-tube shock absorbers are highly gas pressurized and require a force of 445 N (100 lb) in order to initiate shock absorber rod movement. Be careful not to dent or puncture the shock absorber assemblies, or they must be replaced.

  1. Fully extend the shock absorbers with the tires and the wheels unsupported in order to expose the seal cover area for inspection.
  2. Look for signs of leaks at the top of the shock absorber:
  3. • A small amount of fluid in not cause for replacement. The seal permits some seepage to lubricate the shock absorber rod.
    • You can easily determine a leaking shock absorber because an excessive amount of fluid will cover the shock absorber.
  4. Replace a leaking shock absorber.
