Important: The single-tube shock absorbers are highly gas-pressurized and require a force of 445 N (100 lb) in order to initiate movement of the shock absorber rod. Do NOT dent or puncture the shock absorber assemblies.

  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 in order 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.
