wheel bearing units installation need to payattention to what?

Hub bearings for the vehicle is a very important part of the parts, hub bearings in the vehicle to play a role in carrying the body and providing precise guidance for the rotation of the hub, according to the needs of modern vehicles hub bearings are constantly updated, most vehicles on the market now use 2 generation or 3 generation bearings

1, in order to ensure maximum safety and reliability, it is recommended that you always check the hub bearing regardless of the age of the car – pay attention to whether the bearing has early warning signs of wear: including any friction noise during rotation or abnormal deceleration of the suspension combination wheel when turning.
For rear-wheel drive vehicles, it is recommended to lubricate the front hub bearings before the vehicle reaches 38,000 km. When replacing the brake system, check the bearing and replace the oil seal.

2, if you hear the noise of the hub bearing part, first of all, it is important to find the location of the noise. There are many moving parts that may produce noise, or some rotating parts may be in contact with non-rotating parts. If it is confirmed that it is noise in the bearing, the bearing may be damaged and needs to be replaced.

3, because the working conditions of the front hub leading to the failure of both sides of the bearing are similar, so even if only one bearing is broken, it is recommended to replace it in pairs.

4, hub bearings are more sensitive, in any case need to use the right method and the right tools. In the process of storage and installation, bearing components can not be damaged. Some bearings require greater pressure to be pressed into, so special tools are required. Always refer to the car’s manufacturing instructions.

5, the installation of bearings should be in a clean and tidy environment, fine particles into the bearing will also shorten the service life of the bearing. It is very important to maintain a clean environment when replacing bearings. It is not allowed to knock the bearing with a hammer, and be careful that the bearing does not fall on the ground (or similar improper handling). The condition of the shaft and bearing seat should also be checked before installation, even small wear will lead to poor fit, resulting in early failure of the bearing.
