The trunk supports are gas-filled and can wear out over time. As they weaken, they no longer support the weight of your Chevrolet trunk lid or liftgate. The good news is that you can change Chevrolet trunk struts yourself.
- Chevrolet trunk or rear liftgate won't stay up.
- The trunk lid will not stay open.
- Liftgate stays open for a few seconds, then shuts.
- The trunk won't stay open by itself anymore.
- The trunk closes automatically.
What you will need
- Park the Chevrolet on a level surface and set the parking brakes. Turn off the ignition.
Open the trunk or the liftgate and have a friend hold up the trunk as you remove the rear gas struts.
Locate the trunk struts that need to be replaced.
Locate the clip that locks the trunk support locks to the ball joint.
Use a flat screwdriver to pry out the clip that locks the trunk strut in place. Follow the same procedure for the other end. Install the new trunk support in reverse order.
This problem can affect all Chevrolet vehicles as they age.
