Automobile hub bearings pay attention to the early warning signal of bearing wear: including any friction noise during rotation or abnormal deceleration of the suspension combination wheel when turning. In the process of storage, transportation and installation of hub bearings, to protect the bearing components, you must refer to the automobile manufacturing instructions and select special tools for installation. It is recommended to replace the bearings in pairs. There is a problem on one side. For various considerations, the integrity of the other side is questioned, so replacement together is also a preventive method. In order to ensure a long service life of the bearing, the shaft and the bearing seat should be carefully checked before installation, but never hit the bearing with a hard object.

For the hub bearing unit, do not attempt to disassemble the hub bearing or adjust the seal ring of the hub unit, otherwise the seal ring will be damaged and water or dust will enter. Even the raceways of the seal ring and inner ring are damaged, causing permanent failure of the bearing. When installing a hub bearing with an ABS magnetic thrust ring, point the side with the magnetic thrust ring toward the inside, facing the sensitive element of the ABS. If you are not sure on which side the thrust ring is installed, you can use a small thing close to the edge of the bearing. The magnetic force generated by the bearing will attract it. The correct installation is related to the function of the brake system. Ensure that the magnetic thrust ring in the seal ring equipped with the bearing of the ABS device will not be subjected to external forces, including other magnetic field collisions and impacts. When removing it from the packaging box before installation, keep it away from the magnetic field. When installing these bearings, observe the ABS alarm pin on the instrument panel through the road condition test to change the operation of the bearings. Ensure that there is a sufficient amount of grease in the bearing. For some unsealed bearings, such as double-row tapered roller bearings, grease must be added during installation, but sealed is not required. Because the size of the bearing cavity is different, it is impossible to determine how much grease to add. If there is too much grease, when the bearing rotates, excess will ooze out. General experience: During installation, the total amount of grease should account for 50% of the bearing clearance. Due to the difference in bearing type and bearing seat when installing the lock nut, the magnitude of torque varies greatly. Please refer to the relevant instructions.

In order to ensure maximum safety and reliability, it is recommended that you always check the wheel bearings regardless of the age of the vehicle. For rear-wheel drive vehicles, it is recommended that the front wheel bearings should be lubricated when the vehicle travels to 38,000 kilometers. When replacing the brake system, check the bearings and replace the oil seal. In addition, the bearing should be installed in a clean and tidy environment to prevent fine particles from entering the bearing and shorten the service life of the bearing.
