Michigan State Brakes Certification Practice Exam

Question: 1 / 400

What should you do if a newly installed bearing race is loose and can spin in the hub?

Just tighten it

Replace the hub

When a newly installed bearing race is loose and can spin within the hub, the most appropriate course of action is to replace the hub. This scenario often indicates that the hub has been damaged or worn down, preventing the bearing race from fitting securely. A loose bearing race can lead to significant issues, such as premature bearing wear, overheating, and ultimately failure of the wheel assembly, which can compromise vehicle safety.

Replacing the hub ensures that the new bearing race can be installed correctly without further risk of it spinning or shifting during operation. It's crucial to maintain proper tolerances in mechanical components like hubs and races to ensure they function effectively under load. Continuing to use a compromised hub may lead to more severe mechanical failures down the road, making replacement the best long-term solution.
