- Grinding or humming noise: A grinding or humming noise is often the first sign of a failing wheel bearing. The sound is usually worse when you turn or accelerate, and it may go away when you brake.
- Vibration in the steering wheel: If you feel a vibration in the steering wheel when you drive, it could be a sign of a failing wheel bearing. The vibration may be worse at higher speeds.
- Loose or wobbly wheel: If the wheel bearing is loose, the wheel may wobble or feel loose when you shake it.
- Uneven tire wear: If the wheel bearing is not properly supporting the wheel, it can cause uneven tire wear. This is most noticeable on the inside or outside edge of the tire.
- Leaking grease: If you see grease leaking from the wheel hub, it could be a sign of a damaged or failing wheel bearing.
How to diagnose a failing wheel bearing:
If you suspect that your wheel bearings are failing, there are a few things you can do to diagnose the problem:
- Listen for grinding or humming noises: Drive your car in a quiet area and listen for any unusual noises. If you hear a grinding or humming noise that gets worse when you turn or accelerate, it could be a sign of a failing wheel bearing.
- Check for vibration in the steering wheel: Drive your car at different speeds and feel for any vibration in the steering wheel. If you feel a vibration that gets worse at higher speeds, it could be a sign of a failing wheel bearing.
- Check for a loose or wobbly wheel: Park your car on a level surface and try to shake each wheel from side to side. If a wheel feels loose or wobbly, it could be a sign of a failing wheel bearing.
- Check for uneven tire wear: Inspect your tires for uneven wear. If you notice that the tires are wearing more on the inside or outside edge, it could be a sign of a failing wheel bearing.
- Look for leaking grease: Check the wheel hub for any signs of grease leaking. If you see grease leaking, it could be a sign of a damaged or failing wheel bearing.
If you suspect that your wheel bearings are failing, it is important to have them inspected by a qualified mechanic as soon as possible. Replacing a wheel bearing is a relatively simple repair, but it is important to have it done correctly to avoid any potential safety hazards.
