When one of the four hub bearings of the vehicle is damaged, the car in the car you will hear a continuous buzz, this sound can not be said from where, feel the whole car is full of this buzz, and the faster the speed the greater the sound. Here’s how:
Method 1: Open the window to listen to whether the sound comes from outside the car;
Method 2: 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;
Method 3: temporary stop, get off to check whether the temperature of the axle is normal, the method is: touch the four wheel hubs by hand, roughly 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;
Method four: Lift the car up (before loosening the handbrake, hanging neutral), there is no lift when the jack can 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, it is easy to distinguish which axle has a problem with this method.
If the wheel bearing is seriously damaged, there are cracks, pitting or ablation on it, it must be replaced. Before installing the new bearing, grease it first, and then reinstall it in the reverse order, and the replaced bearing must be flexible and free of clutter and vibration
