When Do We Need To Replace Wheel Hub Bearing

 

Bearings are often an important part of tires. In order to make cars run safely, regular maintenance and replacement of bearings are the key. If properly maintained, the bearing of the car can generally be used for about one hundred thousand kilometers.

Traditional wheel bearings are mainly composed of ball bearings or two sets of tapered roller bearings, and with the continuous development of automotive technology, improve the cost of expensive, difficult assembly, poor reliability, invented the wheel hub bearing unit, the two sets of bearings as one, and widely used in the automobile.

Symptoms of bearing damage

If the tire bearing is broken, the abnormal humming sound is the most obvious performance, and the abnormal sound will be louder with the speed of the faster. When the speed can be increased to a certain extent, the car is coasting in neutral. If the buzz is still unchanged, it can be judged that there is a problem with the tire bearing. The body will shake, the faster the shake more intense. If the tire bearing is broken, it will generate large heat, the driver can let the car run for a period of time, touch and feel the tire with his hand, you can obviously feel the temperature of the hub is significantly higher than the normal temperature.

In order to make the wheel hub bearing have a longer service life, it is necessary to regularly maintain it, clean up the stains on the bearing, check whether the running of the bearing is good and replace the grease.
