These step-by-step instructions and video detail a front shock absorber replacement on a 2003 Silverado 1500, and the procedures will be the same for your 1999, 2000, 2001, 2002, 2004, 2005, 2006, and 2007 GMC Sierra 1500 and Chevy Silverado 1500. Replacing worn shock absorbers helps you maintain a safe, working suspension system, and can help you avoid an accident.

Your GMC Sierra 1500 or Chevy Silverado 1500’s front shock absorbers dampen the suspension movement of your truck for a smoother ride. Replacing worn shock absorbers on your 1999-2007 GMC Sierra is a straightforward repair that can help improve your truck’s handling, tire wear, movement, braking time, and the overall ride. If your GMC Sierra 1500’s shock absorbers are failing, you may experience excessive rocking, poor handling, oil leaks near the lower shock tube or shaft seal, knocking noises, damaged rubber bushings, or longer braking time. Exposure to extremely high temperatures and other weather conditions can contribute to failing shock absorbers, and they should be replaced as soon as you suspect a problem in order to prevent tire and suspension damage to your truck. It’s recommended that you inspect or replace your shocks every 50,000 miles, and both shock absorbers on your GMC Sierra 1500 should be replaced at the same time since they have experienced the same amount of use. Our detailed, step-by-step instructions will help you perform a front shock absorber replacement on your 1999-2007 GMC Sierra 1500 or Chevy Silverado 1500.

Park on a level surface.
Raise the front end of the truck… and support the lower control arms with a jack or jack stands.
Removing your wheels may not be necessary, but will give you more room to work.
Applying penetrating oil will help when it comes time to loosen nuts and bolts. Starting on one side, remove the nut at the upper end of the shock. Remove the upper insulator… but do not discard the plastic pilot ring.
Remove the shock absorber mounting bolt at the lower control arm.
You should now be able to remove the shock absorber.
Set it next to your new shock to make sure you have the right replacement. There may be a slight difference in length due to different types of internal rebound bumpers or support springs, but it won’t affect performance.
Before installation, it’s a good idea to prime the shock absorber by fully compressing and letting it extend on its own 4-5 times.
This will ensure that the gas and oil are in the proper position inside the shock, and can help prevent unwanted noise when you start driving with the new shocks in place.
Be sure to have the shock upright with the dust boot or metal shield at the top when priming and when installing.
Twin tube shock absorbers have to be installed in an upright position or they won’t function properly.
Install the new bushing on the stem of the shock. Lift the new shock absorber into place… inserting the stem through the hole in the shock bracket.
