According to the classification wheel bearings refer to bearingm rolling, consisting of two rings, rolling elements and cage, which separates the rolling elements from each other. Most often used in wheel hub double row angular contact, single row deep groove ball and single row tapered roller bearings. Wheel bearings are for the front and rear wheels. They are characterized by high strength and durability to withstand very heavy loads. The reason of their failure can be improper installation.
To avoid this, do not use sharp tools that may damage the surface and integrity of the bearing and cause oil leaks. If you want to press a bearing to the force being transmitted through rolling elements, use the locking pin or clip old parts.
When you install a conical bearing at first correctly adjust the gap on it. If the clearance is too small, the element will overheat. However, a large gap can also cause breakage. About problems with wheel bearings usually shows the characteristic background noise – a clatter or buzzing around the body, right or left.
For a more accurate determination of fault locations will consign the car to the nearest service station, where there is a special stand. There enable a higher gear, give maximum revs and stop the engine. Then you can hear noises from faulty bearings. Diagnosis usually does not take much time.
The procedure of replacing both the front and rear bearings are no different. As practice shows, it is better to replace the wheel bearings in the car with a hydraulic press. Self-replacement without special equipment does not guarantee quality. So, for example, dirt in the bearing can cause damage to the machine.
