Worn or damaged hub bearings or hub units can cause unsuitable and costly failure of your vehicle on the road, or even harm your safety. Please pay attention to the following matters in the use and installation of wheel hub bearings:
1. In order to ensure maximum safety and reliability, it is recommended that you always check the wheel hub bearings regardless of the age of the car - pay attention to the early warning signs of bearing wear: including any friction noise when turning or the suspension combination wheel is turning Unusual deceleration.
For rear-wheel drive vehicles, it is recommended that the front wheel hub bearings should be lubricated when the vehicle travels to 38,000 kilometers. When replacing the brake system, check the bearings and replace the oil seal.
2. If you hear the noise from the bearing part of the hub, first of all, it is important to find the place where the noise occurs. There are many moving parts that can generate noise, and it is also possible that some rotating parts are in contact with non-rotating parts. If it is confirmed that it is the noise in the bearing, the bearing may be damaged and needs to be replaced.
3. Because the working conditions of the bearing failure on both sides of the front hub are similar, even if only one bearing is broken, it is recommended to replace it in pairs.
4. The hub bearing is more sensitive, and in any case, the correct method and suitable tools need to be used. In the process of storage, transportation and installation, the parts of the bearing cannot be damaged. Some bearings require greater pressure to be pressed in, so special tools are required. Be sure to refer to the car manufacturer's manual.
