What should be noticed when installing wheel hub bearing?

In the use and installation of wheel hub bearing, please pay attention to the following matters:
1. Pay attention to the early warning signs of wear of the wheel hub bearing: including any friction noise when turning or abnormal deceleration of the suspension combination wheel when turning.
For rear-wheel drive vehicles, it is recommended that the front wheel hub bearing should be lubricated when the vehicle travels to 38,000 kilometers. When replacing the brake system, check the bearings and replace the oil seal.

2. If you hear the noise from the wheel hub bearing, first of all, it is important to find the place where the noise occurs. There are many moving parts that may produce noise, and it may also be that some rotating parts are in contact with non-rotating parts. If it is confirmed that it is the noise in the bearing, the bearing may be damaged and needs to be replaced.
3. Because the working conditions of the front hub causing the failure of the bearings on both sides are similar, even if only one bearing is broken, it is recommended to replace it in pairs.

4. The wheel hub bearing is more sensitive, and in any case, the correct method and suitable tools need to be used. In the process of storage, transportation and installation, the parts of the bearing cannot be damaged. Some bearings require greater pressure to be pressed in, so special tools are required. Be sure to refer to the car manufacturer's manual.

5. When installing the wheel hub bearing, it should be in a clean and tidy environment. The entry of fine particles into the bearing will also shorten the service life of the bearing. It is very important to maintain a clean environment when replacing the wheel hub bearing. It is not allowed to hit the bearing with a hammer, and be careful not to drop the bearing on the ground (or similar mishandling). The condition of the shaft and bearing housing should also be checked before installation, as even a small amount of wear can lead to poor fit, which can lead to early failure of the bearing.

6. For the wheel hub bearing unit, do not attempt to disassemble the hub bearing or adjust the sealing ring of the wheel hub unit, otherwise the sealing ring will be damaged and water or dust will enter. Even the raceways of the sealing ring and inner ring are damaged, resulting in permanent failure of the bearing.
7. There is a magnetic thrust ring in the sealing ring equipped with the ABS device bearing, which cannot be collided with, impacted or collided with other magnetic fields. Take them out of the box before installation and keep them away from magnetic fields, such as motors or power tools in use. When installing these wheel hub bearings, change the operation of the bearings by observing the ABS alarm pin on the instrument panel through the road test.

8. For a wheel hub bearing equipped with an ABS magnetic thrust ring, in order to determine which side the thrust ring is mounted on, a light and small object can be used to approach the edge of the bearing, and the magnetic force generated by the bearing will attract it. When installing, point the side with the magnetic thrust ring inward, facing the sensitive element of the ABS. NOTE: Improper installation may result in the malfunction of the brake system.
9. Many wheel hub bearings are sealed, and such bearings do not need to be greased throughout their life. Other unsealed bearings such as double row tapered roller bearings must be lubricated with grease during installation. Due to the different sizes of the inner cavity of the bearing, it is difficult to determine how much grease to add. The most important thing is to ensure that there is grease in the bearing. If there is too much grease, when the wheel hub bearing rotates, the excess grease will seep out. General experience: During installation, the total amount of grease should account for 50% of the bearing clearance.
10. When installing the lock nut, the torque varies greatly due to the different wheel hub bearing types and bearing seats. Pay attention to the relevant instructions.
