Rack and Pinion Steering Gear

Rack and pinion gear with bad teeth.

There are two gears in mesh inside of a rack and pinion steering gear. These are the rack and the pinion gear. The pinion gear is the input from the steering column. As it rotates, it moves the rack gear back and forth. At each end of the rack gear is an inner tie rod; this is considered a long rack. If it is received without the inner tie rods attached, it’s considered a short rack. When there’s a damaged tooth on the rack gear of a rack and pinion gear, the steering will slip or bind in that spot. This will require a replacement rack and pinion gear set.
