Failure mode

Sealing: The main form of failure is intrusion from external water and contaminants, causing corrosion of the interface, which in turn accelerates seal wear.


Lubricant: The deterioration of grease is due to aging, water infiltration or base oil loss. The failure of the long-distance running hub unit shows that the bearings steel ball is discolored, and the seal does not fail. In this case, the aged grease becomes harder and the lubricating performance is weakened, which may cause more noise, the shape of the raceway surface changes, slippage or decolorization of the steel ball, and initial fatigue may occur on part of the surface.


Bearing itself: The main failure mode is surface fatigue failure. Surface crack propagation is visible on most failed ferrules with few flaking particles. The peeling expansion is very slow. Other failure modes are in the interior of the contact raceway or in the gap between the steel ball and the raceway. Eventually lead to pitting and initial surface fatigue.


Common abnormal noise problem

When one of the four wheel bearings of the vehicle is damaged, you will hear a continuous humming sound in the car while driving. This sound cant tell where it came from, and it feels like the whole car is inside. It is full of such snoring, and the faster the speed, the louder the sound. The following is the judgment method:

Method 1: Open the window to hear if the sound comes from outside the car;

Method 2: After increasing the speed (when the noise is loud), the gear position is in the neutral position to let the vehicle slide, and observe whether the noise comes from the engine. If the noise does not change when the neutral gear slides, most of the wheel bearings have problems;

Method 3: Temporarily stop, get off and check if the temperature of the axle is normal. The method is: touch the four hubs by hand and feel the temperature is consistent. (When the brake shoes and the gap are normal, the temperature of the front and rear wheels is If there is a gap, the front wheel should be high. If you feel that the difference is not big, you can continue to drive slowly to the repair station;

Method 4: Raise the car with a lift (previously release the handbrake and hang the neutral). When there is no lift, the jack can be used to raise the wheel one by one. The manpower will rotate the four wheels quickly. When the problematic axle is encountered, it will be issued. The sound is completely different from other axles. It is easy to tell which axle has a problem with this method.

If there is severe damage to the hub bearing, there are cracks, pitting or ablation on it and must be replaced. Apply grease before loading new bearings, and then install them in reverse order. The replaced bearings must be flexible and free of miscellaneous and vibration.
