In the process of maintenance, it is often found that some cars have large driving noise, check the tire without abnormal wear and tear, and rotate the wheel on the lift without obvious abnormal noise.This phenomenon is often caused by the abnormal damage of the hub imported bearing, the so-called abnormal refers to the bearing damage caused by the installation reason.
The front wheel bearing of the car is generally a double row ball bearing. When installing the imported bearing, if the hammer is used to strike the installation, or the bearing is installed by pressing the inner ring of the bearing when installing the bearing into the bearing seat, it will cause damage to the bearing raceway on one side.Noise is generated when the vehicle is moving and is not audible when the wheels are off the ground due to the better side of the raceway.Correct installation and operation is the key to long life of bearings.
