How to extend the service life of car wheel hub bearings

To extend the service life of car wheel hub bearings, we can start from the following aspects:

1、 Correct installation and debugging

Select specialized tools: During the storage, transportation, and installation of wheel hub bearings, it is necessary to protect the bearing components and refer to the car manufacturing manual to select specialized tools for installation to avoid damage to the bearings caused by improper use of tools.

Paired replacement: If there is a problem with one side of the bearing, it is recommended to replace the other side of the bearing in pairs, as the working conditions of the two sides of the bearing are similar, and damage to one side may indicate potential problems on the other side as well.

Avoid hitting: During installation, never use hard objects to hit the bearings to avoid damaging the bearing components or affecting their performance.

Pay attention to the sealing ring: Do not attempt to disassemble the hub bearing or adjust the sealing ring of the hub unit, otherwise it will damage the sealing ring, causing water or dust to enter the interior of the bearing and affect its service life.

2、 Regular maintenance and upkeep

Cleaning and lubrication: Regularly remove the wheel hub bearings, clean them with kerosene or gasoline, and check the wear of the bearings. If the bearing has slight wear, an appropriate amount of lubricating grease can be applied to reduce wear. For sealed bearings, if the inner cavity has already been filled with an appropriate amount of lubricating grease, there is no need to add additional grease.

Replace lubricating oil: Based on the usage of the vehicle, it is recommended to replace the lubricating oil every six months or according to the manufacturer's recommendations to ensure good lubrication of the bearings.

Inspection and adjustment: Regularly check the tightness and fit of the bearings. If the fit clearance is too large or the bearings are loose, they should be adjusted or replaced in a timely manner.

3、 Pay attention to driving habits and road conditions

Smooth driving: Avoid aggressive driving behaviors such as sudden acceleration, sudden braking, and sudden turns, which can exacerbate bearing wear.

Choose good road conditions: When driving in harsh road conditions, slow down to reduce bearing vibration and impact.

4、 Timely replace damaged bearings

If obvious problems such as aging, wear, deformation, or abnormal noise are found in the bearings, regardless of how many kilometers the vehicle has traveled, they should be replaced in a timely manner to ensure driving safety and extend the service life of other components.

In summary, measures such as correct installation and debugging, regular maintenance and upkeep, attention to driving habits and road conditions, and timely replacement of damaged bearings can effectively extend the service life of automotive wheel hub bearings.
