How to Change the Rack & Pinion on a Chevrolet Cavalier
by Jeffrey CaldwellThe Chevrolet Cavalier is a rear steer vehicle, meaning the steering gear and tie rods are located behind the steering knuckles. The rack and pinion unit is bolted to the firewall behind the engine. If you begin to notice a distinct grinding or screeching noise whenever you try and turn the steering wheel of your vehicle, it may be a sign that your rack and pinion unit needs replaced.
