Nine major installation and common sense of automobile hub bearing

- Dec 24, 2017 -

The most of the wheel bearings of a car used to be a pair of single row tapered rollers or ball bearings. With the development of technology, car hub unit has been widely used in cars. The use and use of hub bearing units are increasing, and now it has developed to the third generation: the first generation is composed of double row angular contact bearings. In the second generation, there is a flange for fixing the bearing on the outer raceway. The bearing is simply fixed to the axle by the nut. It makes the maintenance of the car easy. The third generation hub bearing unit is used to match the ABS of the bearing unit and the anti lock brake system. The hub unit is designed to have an inner flange and an outer flange. The inner flange is bolted to the drive shaft, and the outer flange is installed together. Worn or damaged hub bearings or hub units will cause unsuitable and costly failure of your vehicle and even cause damage to your safety.

In the use and installation of hub bearings, please pay attention to the following items:

1, in order to maximize the safety and reliability, no matter how long they suggest you should always check the age of car hub bearing - bearing is early warning signal: including any wear friction noise when rotating or hanging combination wheel when cornering speed is not normal. The rear wheel drive vehicle suggests that the vehicle should lubricate the front wheel bearing at 38000 kilometers. When the brake system is replaced, check the bearing and replace the oil seal.

2. If you hear the noise from the hub bearing, first of all, it is important to find the location of the noise. There are many moving parts that may produce noise, or some of the rotates are in contact with the non - rotating parts. If the confirmation is the noise in the bearing, the bearing may have been damaged and need to be replaced.

3, because the front wheel hub causes both sides of the bearing failure of the working conditions are similar, so even if only a bearing is broken, it is suggested that the pair replace.

4, the hub bearing is more sensitive, and in any case the correct method and appropriate tools are needed. In the process of storage, transportation and installation, the parts of the bearing can not be damaged. Some bearings require greater pressure pressure, so special tools are needed. Be sure to refer to the automobile manufacturing instructions.
