Replacing Shock AbsorbersPrintable version
Degree of DifficultyModerate
Moderate
Estimated Time60 minutes
60 minutes
Point of No Return
The point of no return is determined by your ability to remove the fasteners that hold the old shock absorber units. You may want to review the Freeing Stubborn Fasteners DIY article in the archives, and apply the methods outlined there.

Tools Required
Basic hand tools are needed for this job:
  • Socket wrenches (metric or SAE, depending upon your vehicle)
  • Combination wrenches (metric or SAE, depending upon your vehicle)
  • Large, flat-bladed screwdriver
  • Vise grips (optional, depending upon the type of shock absorber)
  • Rust penetrant
  • Vehicle jack and jack stands

Materials
You can obtain good replacement shock absorbers from your local parts store or your vehicle's dealership. Check the hardware that is included with the shock, since you may need to buy an additional hardware kit to replace the original rusted or broken fasteners.

The Job

Locate your vehicle in a well-lighted level area, either inside or outside. Give yourself plenty of access around each wheel.
1. Jack the car up until one wheel is clear of the ground and support the vehicle with a jack stand. Follow all appropriate safety precautions. Remove the wheel/tire.
2. Once the wheel is removed, locate the lower attachment bolts and nuts of the shock absorber, and remove them. If necessary, use the rust penetrant.

3. If the suspension arms drop when the lower bolt is removed, or if you can't push the bolt out once the nut is removed, you may have to use the jack to take the load off of the lower suspension arm. To do this, you will need to locate your jack under the lower point where the shock absorber attaches to the suspension arm (or the axle). Make sure that the jack is lifting on a solid point on the lower suspension arm or axle. Raise the jack just enough to take the load off the shock or to the point where the shock absorber bolt can be removed.
