The usage methods of third-generation automotive wheel hub bearings mainly include installation, inspection, and maintenance. The following is a detailed explanation of these aspects:
1、 Installation method
preparation
Ensure a clean and tidy installation environment to prevent dust and impurities from entering the bearings.
Use specialized tools and avoid using hammers or other striking tools to prevent damage to the bearings.
Installation steps
The third-generation wheel hub bearing unit usually has an inner flange and an outer flange. The inner flange is fixed to the drive shaft with bolts, and the outer flange installs the entire bearing together.
During installation, ensure that the bearing seat holes are clean and free of dirt and grease, and strictly tighten the bearings and half shaft bolts according to the vehicle maintenance manual.
Be careful not to touch the magnetic coding ring and ensure that the magnetic side (usually the brown side of the oil seal) is installed facing the inside of the wheel.
Inspection after installation
After installation, the bearings should be checked for proper installation to ensure that they are not loose or damaged.
By rotating the wheel hub, check if the bearings are running smoothly and if there are any abnormal noises.
2、 Inspection and maintenance
Regular inspection
Regularly inspect the wheel hub bearings, including checking the tightness, lubrication, and any abnormal sounds.
If loose, worn or damaged bearings are found, they should be replaced or repaired in a timely manner.
Lubrication and maintenance
For bearings that require lubrication, the lubricant should be replaced regularly according to the requirements of the vehicle manual.
When replacing lubricants, the bearings and lubrication system should be thoroughly cleaned to ensure that the new lubricant can fully function.
Maintenance precautions
When disassembling and installing wheel hub bearings, special tools should be used to avoid damaging the bearings or related components.
Do not attempt to disassemble the wheel hub bearings or adjust the sealing ring of the wheel hub unit, otherwise it may damage the sealing ring and cause water or dust to enter.
When maintaining bearings equipped with ABS devices, special attention should be paid not to collide, shock or collide with other magnetic fields on the magnetic thrust ring.
3、 Precautions
Avoid overloading
The vehicle should operate within its rated load range to avoid bearing overload and early failure caused by overloading.
Prevent impact
During the driving process, it is advisable to avoid sudden acceleration, sudden braking, and other violent operations as much as possible to reduce the impact and wear on the bearings.
Correct operation
During driving, the steering wheel and vehicle should be operated correctly to avoid damage to the bearings caused by improper operation.
In summary, the use of third-generation automotive wheel hub bearings requires following the correct installation steps, regular inspection and maintenance, and precautions. These measures can ensure the normal operation and prolong the service life of bearings, thereby improving the stability and safety of car driving.
