It is not normal for a car to make a humming noise when decelerating. Possible causes of the fault include: 1. Wheel axle noise - replace the wheel bearing that is making the noise; 2. Main reducer noise - replace the main reducer bearing; 3. Transmission noise - replace the transmission bearing. Traditional automobile wheel bearings consist of two sets of tapered roller bearings or ball bearings combined. The installation, lubrication, sealing, and clearance adjustment of the bearings are all performed on the automobile production line. The functions of the bearings are: 1. To ensure that the shock absorber can rotate with the wheel when the vehicle is turning, maintaining steering flexibility; 2. The outer ring of the pressure bearing is made of rubber, which maintains a flexible connection between the vehicle body and the shock absorber, preventing vibrations from uneven road surfaces from being transmitted to the vehicle body through the shock absorber while driving.
