Shock Absorber

Inspect/Test/Service/Replace

A shock absorber can be bench tested.

  • First, turn it up in the same direction it occupies in the vehicle.
  • Then, extend it fully.
  • Next, turn it upside down and fully compress it.
  • Repeat this operation several times. Install a new shock absorber if a lag or skip occurs near mid-stroke of the shaft's change in travel direction, or if the shaft seizes at any point in its travel, except at the ends.
  • Also, install a new shock absorber if noise, other than a switch or click, is encountered when the stroke is reversed rapidly, if there are any leaks, or if action remains erratic after purging air.
  • When removing and installing shock absorbers, be sure to follow the aftermarket manufacturer's instructions or those given in the service manual.
