What does steering lash testing measure?

Steering lash testing is a specific procedure used to assess the movement of the steering wheel in relation to the wheels of the vehicle. It measures the amount of play or looseness in the steering mechanism. This is crucial for ensuring that the steering response is precise and that the vehicle handles accurately. When there is excessive lash, it can lead to delayed responses when steering, making it a safety concern.

Monitoring the movement of the steering wheel helps identify wear in key components such as the steering gear, tie rods, and other parts of the steering system. By checking for the proper amount of lash, mechanics can determine if there are any issues that need to be addressed to maintain safe and effective steering performance. Understanding this measurement is vital for performing a comprehensive vehicle inspection and ensuring that steering functions as intended.
