Automobile wheel hub bearings are essential key components in vehicle operation, and the following points should be noted during installation:
1. Thoroughly clean before installation: remove old lubricating grease from the bearing surface and check the fit between the bearing inner diameter and the journal. This helps to avoid overheating or failure caused by tight bearings or poor fit.
2. It is necessary to use specialized tools correctly: use the correct bearing installation tools to ensure that each component is correctly fixed and avoid damaging the components. Do not disassemble the sealing ring and do not strike the bearing.
3. Maintain lubrication: The amount of lubricating grease added should account for 50% of the bearing clearance. Avoid damage and abnormal noises caused by poor lubrication.
4. Pay attention to the direction of bearing installation: During the installation process, ensure that the direction of bearing installation is consistent with the direction of wheel rotation. Otherwise, it may lead to premature wear and failure of the bearings.
5. Check the fit: Before installation, it is necessary to inspect the shaft and bearing seat to avoid early bearing failure caused by poor fit. This requires us to regularly check the bearings for wear.
Overall, only by correctly installing wheel hub bearings can a car drive stably and safely.
