How is steering lash inspected during an automotive inspection?

To inspect steering lash effectively, one of the most reliable methods involves observing the behavior of the wheels while turning the steering wheel from inside the vehicle. This process allows the inspector to directly assess the responsiveness of the steering mechanism. By observing the wheels’ movement relative to the steering inputs, the inspector can identify any excessive play or slack that may indicate a problem in the steering system. If there is considerable delay or lack of synchronization between the steering wheel and the front wheels, it suggests that the steering components may be worn or improperly aligned, which is critical information for ensuring safety and performance.

Other methods, such as examining the steering wheel visually or measuring its diameter, do not provide insight into the actual mechanical play or lash that could affect vehicle handling. Shaking the steering column may not accurately reflect the interaction between the steering wheel and the wheels, focusing instead on the column itself rather than the entire steering system operation. Thus, observing wheel movement while manipulating the steering wheel offers the most accurate assessment of steering lash.
