Wheel Hub

Wheel hub is located in the centre of the wheel. It is mounted on the driving axle and is directly connected with the brake disk. Wheel hubs are ultra reliable car parts. Due to their parameters they do not break even under extreme loads when driving. Wheel hub may damage only in the result of a serious mechanical effect, such as an accident. Wheel hubs are forged or casted of steel. Forged hubs are sturdier, so they are used for the driving axle. 

Wheel hub is replaced only in exceptional cases, after an accident for instance. Damage may also occur because of the material defect. Even if the hub is not completely destroyed, it must be immediately replaced. Even a small crack can result in a serous breakdown. Wheel hub breakdown has serious consequences. For example, the wheel can fall off when driving. The car becomes uncontrollable and it is very difficult to influence the movement of the vehicle.

It is better to dismantle the hub with the mounted wheel. After you remove the cap with the help of a special spanner, unscrew the slotted round nut for hook-spanner. For personal safety use the display stand after the car is lifted up. As the wheel is removed the first, the hub should be fixed. Otherwise the shaft will also rotate.

HOW TO DETECT MALFUNCTIONS OF THE WHEEL HUB

It is quite difficult to diagnose the part malfunctions at an early stage. For this you will need the specialized equipment, which is available at service stations. To find a malfunction on your own, take the following steps:

1. Accelerate the vehicle to 50 km/h and steer from side to side. You will hear distinctive humming sound if the front wheel hubs are damaged. Increase of noise when cornering right indicates breakage of the left bearing. If the hum increases when the car is turning left, then the right bearing needs to be replaced.

1. To check the rear wheel hubs for malfunctions, lift the vehicle using a jack, after that spin the wheels with hand one by one. Vibration and free play will point at the components breakage.

1. Touch the discs after the car stopped. If they are warm, then the wheel hubs are possibly out of order.
