The following are the precautions to be taken when using car wheel hub units:
1. Check the wheel hub unit: Before use, check whether the wheel hub unit is intact and undamaged, and whether there are any notches, dents, or cracks. If any problems are found, the use should be immediately stopped and replaced with a new hub unit.
2. Choose the appropriate wheel hub size: The appropriate wheel hub size should be selected based on the original wheel hub size and kept as consistent as possible to ensure safety and stability.
3. Do not blindly increase the wheel hub: Do not blindly increase the wheel hub, as excessively large wheels may cause unstable tires, increase bumps, and make steering difficult.
4. Choose the appropriate type of wheel hub unit: Car wheel hub unit types include baked paint, electroplating, steel, alloy, etc. Steel wheels are cheap and sturdy, but their appearance is not aesthetically pleasing, they are heavy, have poor heat dissipation, and are prone to rusting; Alloy wheels are lightweight, have low inertia resistance, and good heat dissipation, but they are relatively expensive.
5. Pay attention to the matching of tires and wheels: When replacing tires or wheel hub units, ensure that the size and specifications of the tires and wheels match to avoid excessive wear or damage to the tires.
6. Regular inspection: Regularly check whether the rotation of the hub unit is smooth and whether there is any abnormal noise or vibration. If any problems are found, they should be immediately stopped from use and repaired.
7. Pay attention to safety: When using the hub unit, pay attention to safety and do not use it in adverse weather or high-speed driving to avoid accidents.
