What you need to know about power steering rack and pinion
The power steering rack and pinion is a crucial component that translates the driver's steering wheel input into the movement of the front wheels, connecting to them through tie rods.
A rack and pinion converts steering-wheel rotation into side-to-side movement that turns the wheels through the steering linkage. The correct assembly depends on the vehicle and the steering system: some racks are manual, while others use hydraulic or electric assistance.
