Rear wheel bearing broken performance

The abnormal noise is the main manifestation of the broken rear wheel bearing of the car. To determine whether the rear wheel bearing of the car is broken, you can slide the car in neutral after speeding up. If the buzzing sound does not change, then the rear wheel bearing is broken.

If it is broken, it will generate a lot of heat. After driving the car for a period of time, you can park it on the side of the road and touch the hub axle with your hand. Another point is that when the speed of the car is faster, you can feel the fine vibration of the sole of the foot.

The main causes of damage to the rear wheel bearing of the car are several:

The parts are damaged and rusty, and the entry of foreign objects or the deflection of the escalator will cause damage, and the acidic liquid and moisture remaining for a long time will also cause the parts to rust.

Poor lubrication. If there is insufficient lubricant between the roller body and the raceway, the two will produce dry friction, which will produce an abnormal noise of metal friction.

The problem of distance. There is a proper gap between the components and parts of the car, and when the distance between the roller and the roller table is small, it is easy to friction and heat, causing sintering of the rear wheel bearing.

The detection of the rear wheel bearing of the car is actually not complicated.

The first step is to lift the vehicle with a lift, suspend the wheels and release the handbrake;

In the second step, when detecting non-driving wheels, you can manually turn the wheels from slow to fast to check whether there is noise in the bearings;

In the third step, when detecting the driving wheels, the vehicle is started to let the wheels spin, and the rear wheel bearing is checked for additional noise.

There is also a special case that needs attention. Some rear wheel bearing failures cannot be heard only by tires spinning. The car must be placed on the ground and the rear wheel bearing must be under pressure to make accurate judgments.
