Knowledge about hub bearings

The wheel hub bearing is one of the most important parts, because the wheel hub bearing must bear the lateral and radial pressure, so we must know the installation and maintenance of the wheel hub bearing

1. In order to ensure safety and reliability, it is recommended that you always check the wheel hub bearing no matter how old the car is - pay attention to whether there is an early warning signal of bearing 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 wheel hub bearing when the vehicle has driven 38000km. When replacing the brake system, 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 where the noise occurs. There are many moving parts that may produce noise, or some rotating parts may contact with non rotating parts. If it is confirmed that the noise is from 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 bearings on both sides are similar, even if only one bearing is damaged, it is recommended to replace it in pairs

The hub bearing is like a part of the human body. It is located in the center of the chest and bears a lot of load and pressure. Therefore, it must be checked. In order to make our work better
