With the development of the times, there are more and more people driving, and bearings are also important parts of automobiles. For example, bearings are used on automobile wheels and engines. If you can drive, you may not understand the symptoms of damage to parts. Let's take a look at some knowledge about Automotive Bearings.

The detection of automobile wheel bearings is actually not complicated.

First use a lift to lift the vehicle, hang the wheels in the air and release the handbrake;

In the second step, when detecting non-driving wheels, you can manually rotate the wheels from slow to fast to check whether the bearings are noisy;

In the third step, when detecting the driving wheels, start the vehicle to let the wheels spin to check whether the bearings have extra noise.

There is also a special situation that needs attention. Some bearing failures cannot be heard only when the tires are idling. The car must be dropped on the ground and the bearings can be stressed to make an accurate judgment.

The main reasons for the damage of the rear wheel bearing of the car are:

The parts are damaged and rusted, foreign matter enters or the escalator is deflected will cause damage, and the acidic liquid and moisture will remain for a long time, which will also cause the parts to rust.

Poor lubrication. If the lubricating grease between the roller and the raceway is insufficient, the two will have dry friction, which will cause abnormal noise of metal friction.

Distance issues. There is a suitable gap between the parts and parts of the automobile, and once the distance between the roller and the roller table is small, it is easy to friction and heat, causing the bearing to sinter.
