What does a Wheel Bearing do?

A wheel bearing enables the wheel (and with it the wheel hub) to rotate smoothly on a wheels' upright by reducing the friction between the moving and non-moving parts of the wheel hub. The bearings are usually made up out of roll or ball bearings in which the outer part of the wheel hub can turn. Each wheel is fitted with a set of bearings, most cars have two sets of bearings, one for the inner part of the wheel hub and one for the outer part.

How do you know there is something wrong with a Wheel Bearing?

• When the car vibrates whilst driving.
• When a wheel does not move (bearing has seized).
• When there is a thudding or clunking noise coming from underneath the car.
• When there is a squeaking noise coming from underneath the car.

When should you consider a Wheel Bearing replacement?

Over time the bearings can wear, usually, the bearings wear due to inadequate lubrication. In severe cases, it might be that a bearing fails completely. The result is generally a squeaking or grinding noise coming from one of the car's wheels.

Bearings are either sealed or unsealed. Unsealed bearings can be regreased and reused (if not damaged), sealed bearings on the other hand cannot be reused but can only be discarded and replaced if worn out.

Addressing issues with the wheel bearings timely and professionally is key to prevent further, more expensive, damage. It is therefore also recommendable not to drive the car when noticing a shudder through the steering wheel or if you feel the wheels shaking.

Should you experience problems with the bearings then it is advisable that you have them inspected as soon as possible and, if necessary, have the bearings replaced. Always remember to service the bearings as and when stipulated in the guidelines set out by your car's manufacturer.
