What is the maximum allowable steering movement for an 18 inch steering wheel?

The maximum allowable steering movement for an 18-inch steering wheel is 2.25 inches. This standard is established to ensure that the steering system is responsive and that drivers can maintain control over the vehicle. Steering play, which is the amount of movement in the steering wheel before the wheels begin to turn, is critical for safety; excessive play can lead to difficulties in maneuvering the vehicle accurately.

The specified allowance of 2.25 inches provides a balance between responsiveness and comfort, providing enough feedback to the driver while minimizing the potential for oversteering. This limit is crucial in vehicle inspection, as it helps identify any potential issues with the steering assembly that could compromise the overall safety of the vehicle. Regular checks against this standard ensure that steering components are functioning properly and can help prevent accidents caused by steering failures.
