What is the maximum allowable excess steering wheel play?

• A. 5 degrees in either direction
• B. 10 degrees in either direction
• C. 15 degrees in either direction
• D. None; there is no play limit

Answer: (B)

The main idea here is how much free steering movement is allowed before the steering linkage engages the wheels. In the firefighter vehicle standards, a limit is set to ensure you still respond promptly and predictably to steering inputs while allowing normal wear and tolerances. The maximum allowable excess steering wheel play is 10 degrees in either direction. This means with the wheels straight, you can rotate the steering wheel up to about 10 degrees before the steering linkage begins moving the wheels. If you find more play than that, it signals worn or loose components such as the steering gear, pitman arm, tie-rod ends, or center link, and the system should be inspected and repaired to maintain safe control. Smaller limits would be overly strict, while a larger limit would compromise steering responsiveness, and there is indeed a defined limit.
