What Happens to the Damage of the Car Wheel Bearing? What Happens to the Damage of the Car Wheel Bearing?

When one of the four wheel bearings of the vehicle is damaged, you will hear a continuous hum in the car while driving. This sound is unclear where it came from. I feel that the entire car is full of such buzz. The car is faster and the sound is louder. The following is the judgment method:

Method 1: Open the window to hear if the sound comes from outside the car;

Method 2: After increasing the speed of the car (when the hum is loud), hang the neutral gear to let the vehicle slide. Observe whether the noise is from the engine. If the vehicle does not change when the vehicle is in neutral, it is mostly a problem with the wheel bearing;

Method 3: Temporary parking. Get off and check if the temperature of the axle is normal. The method is: touch the four wheels by hand, and roughly feel whether their temperature is consistent. (When the brake shoes and the gap are normal, the temperature of the front and rear wheels is different. The front wheel is high.). If you feel that the difference is not big, you can continue to drive slowly to the repair station;

Method 4: Raise the car with a lift (release the handbrake and hang the neutral before this). If there is no lift, you can use the jack to raise the wheel one by one. Rotate four wheels quickly. When it encounters a problematic axle, it will make a sound that is completely different from the other axles. It is easy to tell which axle has a problem with this method.

If the hub bearing is severely damaged and there are cracks, pitting or ablation, it must be replaced. Apply grease before installing new bearings, and then install them in reverse order. The replaced wheel bearing must be flexible and free of miscellaneous and vibration.
