Hub bearings - mechanisms that are rolling bearings. Their main task is to ensure uniform rotation of the wheel around the axis. Such bearings are divided into single-row and double row, they are also closed or open. The wheel bearings are used both in passenger and cargo cars. It is worth noting that the rear and front hub bearings have some differences among themselves.

Front hub bearing, where there are fault signs

The front hub bearings in the car are subject to extreme loads - high temperature differences, the effect of the environment, the formation of shock loads during arrival in the pit, steering, brakes, drive. Lufts should not prevent the rotation of the wheel, it is important that it rotates with minimal friction and allowable noise.

However, despite actually colossal loads, hub bearings are durable and very durable. In braking and acceleration, there is an increased pressure, and during the move, they have no effect on them, and several forces.

Very often, the owners of the vehicles remember about these parts only when an extra noise occurs when the wheels occurs. The most common problems are incorrect operation or installation of front hub bearings.

The appearance of problems with the front hub bearings will be indicated by such signs - a strong hum or noise that is most noticeable when turning turns, the appearance of the backlash in the wheel, which is also accompanied by noise or tapping.

Which bearing to choose

As a rule, conical single-row roller type bearings are found in the front hub. Mechanisms are more complicated most often used on front-wheel drive vehicles. Such bearings are able to withstand huge loads, but prices for them differ significantly. Closed-type hub bearings are easier to operate - in the manufacture of the lubrication composition in them and there will be no need to replace. They are completely sealed and disassemble them. Open roller bearings require constant care. If the bearing status is constantly monitoring, the front hub bearings may well listen to 130 thousand mileage kilometers.

How to remove the bearing by the puller without removing the swivel fist from the car, the pros and cons of this removal

This method is good in that it is not necessary to affect the collapse adjustment bolt. However, his minus is uncomfortable work, and replacing the bearing without a lift or observation pit will be extremely difficult. Issue and pressing the bearing, as well as, knocking out the hub in this position is very uncomfortable.

How to remove the bearing removing the rack of the whole, dignity and disadvantages

This method is the most time consuming. To remove the rack, it is necessary to cut the steering tip, then unscrew the nuts that the upper support is fixed to the body.

Now, on the removed with the auto rack, the bearing should be replaced. It is a little difficult and time takes a lot.

How to remove the bearing removing the swivel fist from the car, dignity and disadvantages

When removing the rotary fist, the bearing replacement is substantially easier and more convenient, however, it is possible to break the adjustment of the vehicle collapse. Before unscrewing the bolts that are attached to the rack of the swivel fist, two labels should be put. One label marks the position to the stand of the adjusting bolt, and the second is the position to the rack of the swivel fist. During the assembly, the label data should be achieved.

Even if the initial accuracy does not get achieved, the error will be minimal. This method is well suited to drivers who change not only the bearing of the front hub, and also produce routine - replacing steering tips, silent blocks of levers, ball supports and so on.

Tips of professionals

The replacement of the front hub bearing is a bit more complicated than replacing the rear hub bearing, but you can perform such work by following our advice and having the necessary tools at hand.
