What is measured to determine steering wheel lash during the inspection?

To determine steering wheel lash during a vehicle inspection, the movement of the wheels is measured. This process involves assessing how much the steering wheel can be turned without causing a corresponding movement in the vehicle's wheels. This measurement is crucial because it helps to identify any excessive play in the steering system, which can be indicative of wear or a need for adjustment.

When there is too much lash, it can lead to poor handling and response from the vehicle, which is a safety concern. The inspection process aims to ensure that drivers have precise control over their vehicles at all times. Therefore, measuring the movement of the wheels provides a direct way to assess the effectiveness and reliability of the steering mechanism.

The other options, while related to vehicle inspection, do not directly address the specific metric needed to evaluate steering wheel lash. The degree of rotation refers to the amount the steering wheel can turn but does not reflect the efficiency of wheel movement in relation to that rotation. The distance from the floor and the height of the steering column pertain to ergonomics and driver comfort rather than the mechanical integrity of the steering system.
