Owners of the GM truck and SUV models listed below may comment that they are hearing a pop, click or clunking noise coming from their steering at low speeds when going over bumps. They could also report feeling a clunk in the steering wheel. All these concerns can be fixed easily by replacing a worn right steering rack bushing.

An easy way to check for a worn steering rack bushing is to slide under the front of the vehicle while it’s on the ground to get a clear view of the power steering rack. With the engine off, have another tech move the steering wheel back and forth or lightly bounce the vehicle’s front end. Watch for movement of the steering rack. If there is any perceivable movement, replace the steering rack bushing.
