In the past, many car wheel hub bearings were paired with single row tapered roller or ball bearings. With the development of technology, sedan wheel hub units have been widely used in cars. The scope and usage of wheel hub bearing units are increasing day by day, and have now developed to the third generation: the first generation was composed of double row angular contact bearings. The second generation has a flange on the outer raceway for fixing the bearing, which can be easily fitted onto the axle and fixed with nuts. Make car maintenance easier. The third generation wheel hub bearing unit adopts a combination of bearing unit and anti lock braking system ABS. The wheel hub unit is designed with an inner flange and an outer flange. The inner flange is fixed to the drive shaft with bolts, while the outer flange installs the entire bearing together. Worn or damaged wheel hub bearings or wheel hub units can cause inappropriate and costly failures of your vehicle while driving, and even pose a threat to your safety.

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

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 reaches 38000 kilometers. When replacing the brake system, check the bearings and replace the oil seal.

If you hear noise coming from the hub bearing area, the first thing is to identify the location where the noise is occurring. There are many moving parts that 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.

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.

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.
