1. 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 come into contact with non rotating parts. If the noise in the bearing is confirmed, the bearing may be damaged and need to be replaced.
2. Because the working conditions leading to bearing failure on both sides of the front hub are similar, even if only one bearing is damaged, it is recommended to replace it in pairs.
3. Hub bearing is sensitive, so it is necessary to adopt correct methods and appropriate tools in any case. During storage, transportation and installation, the components of the bearing shall not be damaged. Some bearings require high pressure, so special tools are required. Be sure to refer to the automobile manufacturing instructions.
