Turn steering-wheel input into controlled, power-assisted wheel movement with the TERREPOWER Vision OE Steering Gear, part number N503-0190. This new power steering gear is a direct-fit replacement for the 2011-2021 Chevrolet Silverado 2500 HD, 2011-2021 Chevrolet Silverado 3500 HD, 2011-2021 GMC Sierra 2500 HD and 2011-2021 GMC Sierra 3500 HD. See the "Vehicles it fits" section for engine details.
The steering gear links the steering column to the steering linkage. It converts rotation of the steering wheel into the motion that turns the wheels, and power assist reduces the effort needed at the wheel.
Signs a steering gear may need replacing include fluid leaking at the gear, excess free play or looseness in the steering wheel, heavy or uneven steering effort, and a truck that wanders. The pump, hoses, linkage and alignment can cause similar symptoms, so diagnose the cause before you replace the gear. Follow the vehicle service information for installation, torque values and bleeding the power steering system. The same information gives the correct fasteners and says whether they may be reused.
