How to Determine if a Wheel Bearing is Damaged?

[LaLorenzo]

There are several methods to determine if a wheel bearing is damaged: 1. Observe whether the vehicle emits a humming noise during driving. The noise from a damaged bearing is different from the engine's inherent noise. Open the window to check if the sound is coming from outside the vehicle. 2. Place your left hand on the shock absorber spring and rotate the tire with your right hand. Feel the vibration with your left hand to observe if the spring has significant vibration. If the spring vibrates noticeably, it indicates bearing damage. 3. Make a temporary stop and check the temperature of the wheel hub. If there is a significant temperature difference between the front and rear wheels, it indicates bearing damage. 4. Hold the wheel firmly and shake it back and forth, up and down, to check for any looseness in the wheel bearing. If there is looseness, it indicates bearing damage.
