1. In order to ensure maximum safety and reliability, it is recommended that you always check the hub bearing regardless of the length of the car – pay attention to whether the bearing has early warning signs of wear: including any friction noise during rotation or suspension of the combined wheel in the turn When the speed is not normal. For rear-wheel-drive vehicles, it is recommended to lubricate the front hub bearings when the vehicle travels to 38,000 km. When replacing the brake system, check the bearings and replace the oil seal.
2. If you hear the noise from the Tilting pad journal bearing parts of the hub, 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 come into 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. Because the front hub causes the working conditions of the bearings on both sides to be similar, it is recommended to replace them in pairs even if only one bearing is broken.
