Question

Quizplus · Accepted Answer

Both technicians are correct. A loose worm shaft thrust bearing preload adjustment can cause excessive steering wheel free play because it creates a gap between the worm gear and the sector gear, which leads to excessive movement of the steering wheel. Similarly, a loose sector shaft lash adjustment can cause excessive steering wheel free play because it allows the sector gear to move back and forth, resulting in a loose or unstable steering feel.
