How does the rack and pinion work on a car?
The steering column turns when you turn the steering wheel, causing the pinion also to turn. The pinion gear engages with the rack and moves the rack in the direction and amount required to make the turn you desire. Steering can be either power or manual, with most last-model cars (since the mid-70s) having power steering.
