ACDelco GM Original Equipment Remanufactured Rack and Pinion Assemblies convert the rotation of your vehicle's steering column to the side-to-side motion needed to steer its front or rear wheels, and are GM-recommended replacements for your vehicle's original components. Remanufacturing rack and pinion assemblies is an industry standard practice that involves disassembly of existing units, and replacing components that are most prone to wear and failure with new components. Damaged and obsolete parts are replaced and are end of line tested to ensure they perform to ACDelco specifications. In addition, remanufacturing helps return components back into service rather than processing as scrap or simply disposing of them. These rack and pinion assemblies will provide the same performance, durability, and service life you expect from ACDelco. ? WARNING: Cancer and Reproductive Harm -

FAQ - Answer 1Yes. Hydraulic power steering systems use a pump to send pressurized fluid to the hydraulic steering gear, where pressurized fluid assists the driver in moving the steering gear. Electric power steering systems do not use fluid; instead, they use an electric motor and sensors to move the steering gear.
FAQ - Answer 2Yes. If there is a power steering pump mounted to your vehicle's engine, or your owner's manual calls for power steering fluid, then your vehicle uses a hydraulic power steering system. If your vehicle's engine does not have a power steering pump or your owner's manual indicates your vehicle does not require power steering fluid, then your vehicle uses an electric power steering system.
FAQ - Answer 3Yes. Uneven tire wear, vehicle pull, or an off center steering wheel may indicate that your vehicle requires an alignment.
FAQ - Answer 4Yes. You will be able to steer your vehicle if the power steering goes out for both hydraulic and electric power steering systems. It will require more effort, especially at lower speeds. If your vehicle has electric power steering, a 'service steering system' light will likely be visible before it is apparent that the power assist is off. If your power steering goes out, have the system inspected and repaired as soon as possible.
