Struts or Shock Absorbers Weak

Use the following steps in order to inspect the struts:
1. Inspect and adjust the tire pressures to the pressures specifications shown on the tire placard. The tire placard is located on the driver's side door lock pillar.
2. Note the load conditions under which the vehicle is normally driven.
3. Ride in the vehicle with the owner in order to verify the complaint.
4. Use the following procedure in order to test the strut dampeners/shocks:
4.1. Push down on the corner of the bumper nearest to the strut dampener/shock being inspected.
4.2. Quickly lift up the corner of the bumper nearest to the same strut dampener/shock being inspected.
4.3. Repeat the above push/pull action on each corner of the vehicle in turn in order to test each strut dampener/shock absorber.
4.4. Note the compression and the rebound.
4.5. Compare the compression and the rebound with a similar vehicle that has an acceptable ride quality. Both of the strut dampeners/shocks should provide the same feeling of resistance.

Use the following steps in order to inspect the shock absorbers:
1. Support the rear suspension in order to unload the shock mounts.
2. Disconnect the lower shock mountings on one axle set.
3. Stroke the shocks at various rates of speed, through maximum travel in both directions.
4. Compare the two sides for rebound and compression resistance.
^ Rebound resistance is normally twice as Strong as compression.
^ The right and left shocks must feel comparable.
^ Differences between front and rear shocks are normal.
^ If you are in doubt about the condition of the shock, compare the shock with a shock that is known to be good.
