Installation and usage of the vehicle wheel hub bearings

Please pay attention to the following matters in the use and installation of wheel hub bearings:

1. To ensure maximum safety and reliability, it is recommended that you regularly check the wheel hub bearings regardless of the age of the vehicle - paying attention to early warning signals of bearing wear, including any friction noise during rotation or abnormal deceleration of the suspension combination wheels during turning. For Rear Wheel Drive vehicles, it is recommended to lubricate the front wheel hub bearings when the vehicle has traveled 38000 kilometers. When replacing the brake system, check the bearings and replace the oil seal.

2. If you hear noise coming from the hub bearing area, the first thing is to identify the location where the noise is occurring. Many moving parts may produce noise, and it is also possible that some rotating parts have come into 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 for bearing failure on both sides caused by the front wheel hub are similar, even if only one bearing is damaged, it is recommended to replace it in pairs.

4. Wheel hub bearings are sensitive and require the correct method and appropriate tools in any situation. During storage, transportation, and installation, the components of the bearings must not be damaged. Some bearings require significant pressure to be pressed in, so specialized tools are needed. Be sure to refer to the car manufacturing manual.

5. When installing bearings, they should be in a clean and tidy environment, as small particles entering the bearings can also shorten their service life. It is very important to maintain a clean environment when replacing bearings. Do not use a hammer to strike the bearing, and be careful not to drop the bearing on the ground (or handle it improperly). Before installation, the condition of the shaft and bearing seat should also be checked, as even minor wear can lead to poor fit and early failure of the bearings.

6. Do not attempt to disassemble the hub bearing unit or adjust the sealing ring of the hub unit, as this may damage the sealing ring and allow water or dust to enter. Even the sealing ring and the raceway of the inner ring are damaged, causing permanent failure of the bearing.
