Shock absorbers require replacement if the vehicle fails to recover quickly after hitting a large bump or if it sways excessively following a directional change.
A good way to test the shock absorbers is to intermittently apply downward pressure to the side of the vehicle until it is moving up and down for almost its full suspension travel. Release it and observe its recovery. If the vehicle bounces once or twice after having been released and then comes to a rest, the shocks are all right. If the vehicle continues to bounce, the shocks will probably require replacement.
REMOVAL & INSTALLATION
See Figures 1 and 2
