What are the symptoms of broken front wheel bearings

The front wheel bearing is the front wheel of the car. If the baiguo is that the front wheel du bearing is damaged, if it is not very serious, the noise will be loud after driving and it will make a buzzing sound, which is different from the tire noise. You can drive for half an hour. After getting off the car, gently touch the part of the wheel hub that you think damages the bearing. If the bearing is damaged, the heat generated will be very high and it is estimated that it will be hot. Different from normal temperature, if it is to change it decisively.

If the damage is severe, the heat will be generated faster, which will hurt your axle and end cover. This sloppy, speed replacement, go to the auto parts city to buy a replacement to find a maintenance department. Because the 4S shop will be very expensive, it is not necessary.

Extended information:

The main function of the hub bearing is to support the load and provide precise guidance for the rotation of the hub. It is a very important component that bears both axial and radial loads. The traditional automobile wheel bearing is composed of two sets of tapered roller bearings or ball bearings. The installation, oiling, sealing and clearance adjustment of the bearings are all carried out on the automobile production line.

This structure makes it difficult to assemble in the automobile production plant, high in cost, and poor in reliability. Moreover, when the automobile is maintained at the repair point, the bearings need to be cleaned, oiled, and adjusted.

The hub bearing unit is developed on the basis of standard angular contact ball bearings and tapered roller bearings. It combines two sets of bearings into one body, has good assembly performance, can omit clearance adjustment, light weight, compact structure, and load capacity Large, sealed bearings can be pre-loaded with grease, omit the external hub seal and free from maintenance, etc., have been widely used in cars, and there is also a tendency to gradually expand the application in trucks.

we are tapered roller bearing supplier,you can know it.
