9 points to maintenance of the car bearings wheel hub bearings.

1. In order to ensure maximum safety and reliability, it is recommended that you always check car bearings wheel hub bearings. regardless of the age of the car - pay attention to whether the bearing has an early warning signal of wear and tear: including any friction noise during rotation or hanging combination wheel turning Unusual deceleration. For rear-wheel-drive vehicles, it is recommended that the front hub bearing be lubricated when the vehicle is driven to 38,000 kilometers. When replacing the brake system, check the bearing and replace the oil seal.
2. If you hear noise from the car bearings wheel hub bearings., first of all, it is important to find where the noise occurs. There are many moving parts that may generate noise. It may also be that some rotating parts come into contact with non-rotating parts. If it is confirmed that the noise is in the car bearings, the bearing may be damaged and needs to be replaced.
3. Because the working conditions of the front hub causing the failure of both sides of the car bearings are similar, even if only one bearing is broken, it is recommended to replace it in pairs.
4. Hub bearings.are sensitive and in any case need to use the right method and the right tool. During the storage and installation process, the bearing components cannot be damaged. Some car bearings require a large pressure press, so special tools are required. Must refer to the automobile manufacturing instructions.

5, the installation of car bearings should be in a clean and tidy environment, small particles into the bearing will shorten the bearing life. It is very important to maintain a clean environment when replacing bearings. It is not permissible to tap the bearing with a boring head and note that the car bearings should not fall to the ground (or a similar mishandling). The condition of the shaft and car bearings housings should also be checked prior to installation. Even minor wear can lead to poor fit and cause early bearing failure.
6. For hub bearing units, do not attempt to disassemble the hub bearing or adjust the seal of the hub unit, otherwise the seal may be damaged resulting in the entry of water or dust. Even the raceways of the seal ring and the inner ring are damaged, causing a permanent failure of the bearing.
7. There is a magnetic thrust ring in the sealing ring of the bearing equipped with ABS device. This kind of thrust ring can not be impacted, impacted or collided with other magnetic fields. Remove from the box before installation and keep them away from magnetic fields, such as motors or power tools used. When installing these bearings, change the bearing operation by observing the ABS alarm pin on the instrument panel through road conditions.
8, car bearings wheel hub bearings. equipped with ABS magnetic thrust ring, in order to determine which side of the thrust ring is installed, you can use a light and small thing near the edge of the bearing, bearing the magnetic force will attract it. The side with the magnetic thrust ring points inward when mounting, facing the sensitive element of ABS. Note: Improper installation may result in malfunction of the brake system.
9, many car bearings wheel hub bearings. are sealed, this type of bearing does not require grease during the entire life. Other non-hermetic bearings such as double row tapered roller bearings must be greased during installation. Because of the different sizes of the inner cavity of the bearing, it is difficult to determine how much oil is added. The most important thing is to ensure that there is grease in the bearing. If the grease is too much, excess grease can seep out when the bearing rotates. General experience: At the time of installation, the total amount of grease accounts for 50% of the bearing clearance. 10. When the lock nut is installed, the torque varies greatly depending on the type of bearing and the bearing seat.
Maintenance note editing OF car bearings wheel hub bearings.

car bearings
In the course of maintenance, it is often found that some vehicles have a large amount of running noise, no abnormal wear of the tires is checked, and there is no noticeable noise in turning the wheels on the lift. This phenomenon is often caused by the abnormal damage of car bearings wheel hub bearings. The so-called abnormality refers to car bearings wheel hub bearings damage caused by the installation. The front wheel bearing of a car is generally a double-row ball bearing. If the hammer is used to install the bearing when installing the bearing, or when the bearing is installed into the bearing seat, the bearing ring may be installed by pressing the inner ring of the bearing. damage. When the vehicle is running, noise is generated, and when the wheels are off the ground, there is a good side of the raceway, so no noticeable noise can be heard. Proper installation is the key to the long life of car bearings wheel hub bearings..
