How does rack and pinion steering work?

Rack and pinion steering converts the rotational motion of the steering wheel into linear motion to turn the wheels. A pinion gear on the steering column meshes with a toothed rack, and as the pinion rotates, it moves the rack left or right. The rack connects to tie rods that push or pull the steering knuckles to turn the wheels. It is simple, provides direct feedback, and is used in most modern vehicles.
