1. Noise: A common symptom of a bad hub bearing is a humming or grinding noise that increases with speed. The noise may be especially noticeable when turning or driving on rough roads.
2. Vibration: A bad hub bearing can also cause vibrations in the steering wheel or floorboard of the car. These vibrations may be felt at all speeds, but are often more pronounced at higher speeds.
3. Play in the Wheel: If the hub bearing is severely worn, there may be play or looseness in the wheel when it is turned by hand. To check for play, grasp the tire at the top and bottom and try to move it in and out. If there is any noticeable movement, the hub bearing may be bad.
4. Uneven Tire Wear: A bad hub bearing can cause the tire to wear unevenly, resulting in cupping or scalloping of the tread. If you notice uneven tire wear, especially on the inside or outside edge of the tire, it could be a sign of a bad hub bearing.
If you suspect that you may have a bad hub bearing, it is important to have it inspected and repaired as soon as possible to prevent further damage to your vehicle. A qualified mechanic can diagnose the issue and perform the necessary repairs.
