Long-term wading is the incentive-How to extend the service life of auto wheel hub bearings?With the increase of vehicle mileage, many drivers have encountered the problem of abnormal wheel noise. And this kind of abnormal noise is often related to the speed of the vehicle, the faster the speed, the greater the abnormal noise. Many people think it is tire noise and ignore it. As everyone knows, this is likely to be the abnormal noise caused by the wear of the wheel hub bearing. Do you know what causes the abnormal sound of the wheel hub bearing? How can we prolong its life? Today, Taizhou Dongna will talk to you about what should be paid attention to when using wheel bearings!1.Fault phenomenon of wheel hub bearing1.1Abnormal noise: There is a "buzzing" abnormal sound on a certain wheel when the vehicle is driving. As the speed of the vehicle increases, the abnormal sound goes home.1.2 Clearance: There is a radial clearance in the left and right shaking wheels. If the clearance is serious, the steering wheel will vibrate or deviate when the vehicle is driving.2.Second, what is likely to cause damage to the wheel hub bearing?2.1 Water wading: wading is the most important factor threatening the service life of wheel bearings. If you drive in deep water for a long time, especially where the water depth is more than half of the wheel, it is easy to cause the bearing to seep and rust, resulting in internal wear.2.2 Loose bolts: The wheel hub bearings of some models are fastened by CV JOINT nuts. If the nuts are loose for a long time, the bearings will wear out.2.3 Damage to the wheel hub bearing sealing ring: In order to prevent dust and sewage from entering the interior of the wheel bearing and prevent the internal grease from being thrown out, the hub bearing will be designed with a sealing ring. Long-term wear and aging of this sealing ring will lead to poor sealing and internal water ingress.3. Where is the wheel hub bearing installed?Hub bearings are installed inside the steering knuckle of the wheel. Divided into integrated bearings with the hub and independent bearings. The four wheels are respectively equipped with four wheel hub bearings. After a certain bearing fails, the abnormal sound produced by the wheel on one side will be obviously heard. If the wear is serious, the abnormal sound will be more obvious if the wheel is suspended in the air and rotated.4. Disassembly and assembly of wheel hub bearings4.1 Disassemble the wheel: the design of the wheel hub bearing of each model is different, so I will not introduce it in detail. Briefly explain how to disassemble the hub bearing. Take off the wheel after suspending the wheel first.4.2 Disassemble the CV JOINT nut: the bearings are fastened through the CV JOINT nut, so we need to check the tightness of the CV JOINT nut regularly. It's okay to have a lock like this. If not, the nuts need to be tightened periodically. To remove the bearing, the CV JOINT nut must be removed.4.3 Disassemble the brake system: the next step is to disassemble the brake calipers and brake discs. For most of the Wheel bearings integrated with the hub shaft, it can basically be removed after the brake disc is removed.4.4 Remove the wheel bearing: if it is an integrated bearing, that is, the bearing and the hub shaft are designed in one piece. This type of bearing cannot be repaired. After damage, it can only be replaced once, and the maintenance cost is slightly higher.5. How to prolong the service life of auto wheel hub bearings?5.1 Avoid time wading.5.2 Regularly check whether the CV JOINT nut is loose.5.3 During each maintenance, shake the wheel to check whether there is a radial gap. If there is, check whether the gap can be eliminated by tightening the CV JOINT nut.5.4 For maintainable bearings, the hub bearings should be cleaned and oiled every 40,000 kilometers.Finally, the wheel hub bearing is an important part of the driving system, and its quality is directly related to driving comfort and safety. Slight wear will produce abnormal driving noise, but severe wear will seriously affect the stability of the vehicle at high speeds. Therefore, we must pay attention to the wheel hub bearing. It is important to protect its lifespan or to consider the daily driving road conditions. Long-term wading is taboo, which can effectively prolong its lifetime.
