How to judge your car back wheel bearing is broken?

Damaged car back wheel bearing:

First, the wheel shakes when the car runs, and the vehicle shakes aggravated.
Second, the back wheel bearing is damaged and abnormal noise will occur.
Third, the rolling is not smooth, resulting in a decrease in power. The biggest impact is the increased body shake and abnormal noise. It is recommended to replace.

How to know your car back wheel bearing is broken? The judgment method is as follows:
1. Open the car window and check if the sound is coming from outside the car;
2. After increasing the vehicle speed (when the hum is loud), set the gear position to neutral and let the vehicle coast, and observe whether the noise comes from the engine. If the hum does not change when coasting in neutral, it is mostly because of back wheel bearing problems;

3. Stop temporarily and get out of the car to check whether the temperature of the wheel axle is normal. The method is: touch the four wheel hubs with your hands and feel roughly whether their temperatures are the same (when the brake shoe and disc gap is normal, the temperature of the front and rear wheels is If there is a gap, the front wheel should be higher), if you feel the difference is not big, you can continue to drive slowly to the maintenance station;

4. Raise the car with a lift (release the handbrake and put in neutral before). When there is no lift, you can use a jack to lift the wheels one by one, and rotate the four wheels quickly. When encountering a problematic axle, it will make a sound , Which is completely different from other axles, it is easy to tell which axle is the problem with this method.
