Forget about the ball bearings and sliding block.

Think of a bolt with a nut threaded half- way down it. . Hold the nut in one hand and rotate the bolt with the other.
As the bolt turns the nut moves up and down the length of the bolt. Simple.

This steering works in the same way. The bolt is connected to the steering wheel, and the nut is connected to a linkage that moves the front wheels.

Turn the steering wheel and turn the bolt. The nut will move up and down the bolt and will steer the front wheels.

This system uses upper and lower control arms to hold the wheel on.

Each arm is triangular in shape, and attaches at two places to the chassis and one place at the wheel. It looks vaguely like the 'wishbone' (collarbone) of your Christmas turkey, hence the name.
