If you happen to notice that your ride is no longer as smooth as it once was or there is a vibration or clattering when you drive your car, it may be a bad shock absorber. Replacing the shocks are relatively easy compared to other jobs. You may find that the nuts holding the shocks may not loosen as easily as you would like. Use plenty of penetrating oil on the nuts, allowing the oil to soak for a few hours. It is best to change both shock absorbers. You will have to remove the top in order to begin the job.

Before you do any work on your car it is important that you wear safety glasses and work gloves. If you have to jack up your car, make sure to use jack stands and chock your wheels as well as applying the parking brake. Protect your eyes, hands and body from fluids, dust and debris while working on your vehicle. Never work on your vehicle if you feel the task is beyond your ability. Always disconnect the battery before working on your car.

In order to get at the rear shock absorber, you will need to remove the rear seat side panel.
