What part of your steering system attaches to the steering shaft and travels across the rack to turn your wheels?
Answer Pinion
The pinion is a small gear that sits at the end of your steering shaft and travels across a toothed bar known as a rack. The alternative to rack-and-pinion steering is known as a recirculating ball, and it is still in use for many older cars and trucks today.
