Search for Wheel hub rear and front:

Wheel hub is a rotating component of the suspension. If the wheels are driven, it is the component of the transmission. On it the wheels, front and rear brakes are fixed. In the hubs of both front and rear wheels of the car there are used double-row angular contact ball bearings with two-way seal, which must have inner cut ring. In addition, when this part is made before installing the seals, into the bearings cavities plastic lubricant is added. Therefore, the bearings should not be regulated and during their service life lubrication is replaced. Moreover, because the pressed out bearings can not be used again, the bearings should not be removed without the urgent need.

Front wheel hub that is made of chrome steel has three holes in the flange. These holes are necessary to install a tool for removing the bearing. In order to provide additional protection from dirt coming from the constant velocity joints, it provides an additional seal. This kind of the "mudguard" is formed by the centrifugal effect.

As for the front hub wear, it usually is revealed in bearing plays appearance, that is a vertical clearance in the posted wheel. In any case it is impossible to drive with such a problem. If you hear a constant drone, which appears when increasing speed and does not change when picking-up the speed or reducing it, then the problem is in the hub bearings.

Remember that these lead to overheating of the calliper, as well as boiling of brake fluid that result in failure of the braking system. In any case, when the wheel hub fails, it is not repaired, but replaced with a new one. If you want to save when buying wheel hub, bumper, water pump, fixed castor, order them in our online shop.

What is necessary to know about wheel hub replacement: common defects and their signs, tips and recommendations

Average lifetime limit of the wheel hub is 100,000 – 120,000 kilometers. The front hubs are more subject to wear than the rear ones. Thus, the front right hub will breakdown earlier than the rear right hub, even if they were installed at the same time.

The hub is replaced due to lifetime ending or component body deformation, also due to appearance of cracks, chips or other damages on it. Breakdown or wear of the hub bearing may also become the reason for replacement.

Presence of defects is indicated by noise and vibrations from the side of the component during driving. Moreover, defect signs for the front or rear hub are uneven wear-out of tyres on one axle and leakages of grease near the component.

In order to inspect the hub of the front or rear wheel on your own you need to set the car on a lifting platform or lift it with a help of a jack, and after this, grasp the wheel with your hands and try to carefully sway it. It will be easy if the hub is defective. If during swaying of the wheel, its freeplay is noticeable, and noise from the bearing is heard, this indicates breakdown of the hub.

To replace the right or left hub, you need to contact a service station. Specialists unscrew fasteners of needed wheel, lift the car body using a jack, and demount the wheel, and unscrew the hub nut. Then the brake caliper is detached, and the brake disc demounted. After this, the bolts, with a help of which the hub is fastened to the steering knuckle, are unscrewed, and the component is removed. Installation of a new part and unit assembling are performed in the reversed order.
