Wheel Bearing Replacement in Hackbridge | KITH Cars Garage, South London

A wheel bearing allows the wheel hub to spin smoothly on the axle with minimal friction and no play. Modern bearings are sealed units designed to last the lifetime of the vehicle under normal conditions. Pothole impacts, kerb strikes and high mileage can all shorten that lifespan. At KITH Cars Garage in Hackbridge, wheel bearing replacement is carried out at the medium rate of £72 per hour.

The noise that alerts most customers is a low rhythmic hum or drone that increases with vehicle speed. It is easy to mistake for tyre noise, particularly on coarser road surfaces. The test that separates the two is a gentle steering input at 50 to 60 mph on an empty road. If the noise changes noticeably when weight transfers from one side to the other, the bearing is the likely cause. Tyre noise does not respond to steering input in the same way.

Wheel bearings come in two main types. Pressed-in bearings sit in the hub carrier and need a hydraulic press to remove and refit. This adds to the labour time because the carrier has to come off and be taken to the press bench. Bolt-on hub assemblies supply the entire bearing and hub as a single unit that bolts directly to the carrier. The bolt-on type is generally faster and more straightforward.

The ABS speed sensor ring is integrated into the outer race of the wheel bearing on most modern vehicles. When the bearing fails, the ring can be damaged too. This is often what triggers an ABS warning light on a vehicle with a worn bearing. Replacing the bearing resolves the ABS fault at the same time because the new bearing carries a new sensor ring.

Bearing noise can be difficult to locate precisely before the car is on a ramp. We test-drive first to characterise the noise, identify which side is most likely, and confirm the diagnosis by checking the bearing for play and roughness on the lift. After replacement, a road test confirms the noise has gone and the new bearing is running smoothly.

A bearing that has reached the point of making constant noise should not be left long. As the rolling elements continue to wear, the race can fail suddenly. Wheel wobble and loss of steering control in a severe bearing failure are genuinely dangerous.
