GMC Sierra Rack And Pinion provides fast and accurate steering by converting the driver's wheel rotation into side-to-side movement that steers the front tires. In the assembly, a pinion gear on the end of the steering column meshes with a straight rack gear contained in a rigid tube that bolts to the chassis. As the pinion spins, it pushes the rack sideways, pulling the tie rods and steering knuckles so the wheels follow the path commanded. This Rack And Pinion layout helps to minimize play and provides good road feel, which makes every GMC driver feel confident on tight corners. Across different model years, the Sierra has leaned on two main incarnations of the same idea: traditional manual Rack And Pinion units and versions assisted by hydraulic or electric power, the latter making it easier to handle, particularly when a loaded GMC truck is maneuvering at low speed. The Rack And Pinion mechanism lives on the direct engagement of gears without the bulky linkages, and both styles will typically combine the favored straight cut gears with the rack due to their cooler operation, higher torque for a given ratio, and longer life than the noisier helical alternative that can introduce additional side forces and premature wear. Regardless of trim, every Sierra enjoys a Rack And Pinion that allows for low backlash and crisp steering response.
