How does a rack and pinion work?
A rack is a very simple device. The pinion gear meshes with a straight shaft (the rack) that has gear teeth machined into one side and is connected directly to the front wheels. When you turn the steering wheel, the pinion gear turns and moves the rack in the direction of the turn and moves the wheels.

What does steering ratio mean on a rack and pinion?
Rack and Pinion Steering Ratio Moog Parts defines "steering ratio" as the ratio of how far the steering wheel turns to how much the wheels turn. For example, if a 360-degree turn of the steering wheel causes a car's wheels to turn 20 degrees, then that car's steering ratio is 18:1 (360 divided by 20).

To do this, the steering arm distance can be measured between the end of the steering arm, where the tie rod connects, and a symmetrical part attached to the knuckle, like the axle joint or bearing assembly. The steering arm position can also be measured to a straightedge placed against the hub or rotor.
