The symptoms of wheel bearing damage are as follows: 1, after increasing the speed (when the buzz is large), put the gear in neutral to allow the vehicle to glide, observe whether the noise comes from the engine, if the buzz does not change when the neutral glide, it is mostly a problem with the wheel bearing.
2, temporary stop, get off to check whether the temperature of the axle is normal, the method is: touch the four wheel hubs by hand, feel whether their temperature is consistent (brake shoes, the gap between the front and rear wheels is normal, the front wheel should be high), if you feel the difference is not big, you can continue to drive slowly to the maintenance station. 3, with the lift to lift the car (before loosening the handbrake, hanging neutral), no lift can be used to lift the wheels one by one, the manpower quickly rotate four wheels, when there is a problem with the axle, it will make a sound, and other axles are completely different, with this method it is easy to distinguish which axle has a problem.
