Your heavy-duty Sierra pickup delivers powerfully whenever you need it, no matter what the job is. Hard use wears down the parts after time, though, which is why it's important to plan for a replacement GMC Sierra rack and pinion whenever you notice the handling becoming too loose or too stiff.

There are a variety of issues that come with a worn-out Sierra rack & pinion gear set. Extra tire wear, especially uneven wear, is common, and so is the feeling that the car is harder to drive in the morning than it is as the day goes on. Some drivers also report the vehicle wandering in its lane. All of these issues are solved with a quick replacement of those gears, however, and AutoZone is always ready to advise you about your purchase with trustworthy advice from helpful staff in all our locations.
