Hub bearings in the car used to use single columns of conical rollers or ball bearings in pairs.

With the development of technology, cars have been widely used in car wheel hub units.

The use range and usage of hub bearing units are growing, and have now developed to the third generation: the first generation is composed of double columns of angular contact bearings.

The second generation has a flange for fixing the bearing on the outer roller, which can be simply fixed the bearing to the wheel shaft with a nut.

Make the car repair easy.

The third generation wheel hub bearing unit is combined with the bearing unit and the anti-lock brake system ABS.

The hub unit is designed to have inner and outer flanges, which are fastened on the drive shaft and the outer flanges mount the entire bearing together.

Wear or damaged hub bearings or hub units will make your vehicle on the road of inappropriate and high cost failure, and even cause damage to your safety.

During the use and installation of hub bearings: 1. In order to ensure safety and reliability to the maximum extent, it is recommended that you often check the hub bearing no matter how old the car is. —— Pay attention to whether the bearing has an early warning signal of wear: including any rotating friction noise or abnormal deceleration of the suspension combination wheel when turning.

The recommendation for rear-wheel drive vehicles to reach 38,000 km is to lubricate the front hub bearings.

Check the bearings and replace the oil seals when replacing the brake system.

2. If you hear the noise from the hub bearing part, first of all, it is important to find the location where the noise occurs.

There are many moving parts that may produce noise, or some rotating parts are in contact with the non-rotating parts.

If it is confirmed that the noise is in the bearing, the bearing may be damaged and needs to be replaced.

3. Given the similar working conditions for the failure of both bearings caused by the front hub, pair replacement is recommended even if only one bearing is broken.

4, the hub bearing is more sensitive, in any case need to use the right method and appropriate tools.

During storage and installation, the bearing parts shall not be damaged.

Some bearings require large pressure in, so special tools are needed.

Be sure to refer to the automobile manufacturing instructions.
