RACK AND PINION
An increasingly popular type of steering system is rack and pinion. A pinion gear translates the rotary motion of the steering wheel into the linear motion of the rack. The rack acts like the center link, moving the tie rods back and forth to steer the vehicle. Rack placement varies from one car manufacturer to another and from model to model.
Rack and pinion steering provides easy turning and fast steering response because of its low gear ratio (8:1 to 10:1).
