Wheel Bearing
Typical layout and location for the Wheel Bearing assembly.
Symptoms
- Humming, droning, or roaring noise from the wheels that increases with road speed
- Noise changes pitch or disappears when turning slightly left or right
- Slight vibration felt through the steering wheel at motorway speeds
Root Cause
The sealed bearing unit loses its grease over time, or water ingress causes the steel balls/rollers to pit and rust. Impact damage from potholes can also cause a flat spot on the bearing race.
How To Fix
- Jack the car up and check for play by rocking the wheel at the 12 and 6 o'clock positions.
- Spin the wheel and listen for a rough rumbling sound.
- Press out the old bearing and press in a new OEM-quality bearing (e.g. SKF, FAG, SNR).
- Cost: £120-250 per corner
