1. If the wheel bearing is damaged, the wheels will make a noisy "buzzing" noise while the vehicle is running. If we hear this kind of abnormal noise, slow down the speed and carefully feel the source of the abnormal noise to eliminate the tire noise.
2. Lift the vehicle, swing the wheels left and right by hand, check whether there is a gap in the bearings, and then turn the wheels by hand, and feel again whether there will be a "buzzing" abnormal noise.
3. If the abnormal noise is clear, remove the tire bearing on the side where the abnormal noise is emitted and check whether the bearing runs smoothly.
4. If the bearing is running smoothly and there is no sign of damage, it can be guessed that the lack of lubrication at the half shaft spline. Try to apply grease on the half shaft spline and bearing spline before testing. If the bearing is damaged, just replace it.
