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.
