1  In order to ensure maximum security and reliability, it is recommended that you no matter how long vehicles will check regularly whether the SKF wheel hub bearings ,http://www.alierbearings.com/brand/skf/index38.html   pay attention to the bearing wear of early warning signals, including any rotating friction noise or suspension combination of abnormal wheel in turn.
The vehicle recommended for the rear wheel drive is to be lubricated by the front wheel bearing for driving to 38,000 km.
When changing the braking system, check the bearing and replace the oil seal.
2  If you hear the noise of the SKF wheel hub bearings part, first of all, it is important to find the location of the noise.
There are many moving parts that may produce noise, or some of the rotating parts that are in contact with the non-rotating parts.
If the noise in the bearing is confirmed, the bearing may be damaged and needs to be replaced.
3  Because the front wheel causes the working conditions of the bearing failure on both sides to be similar, it is recommended to replace the bearing even if only one bearing is broken.
4  Wheel hub bearings are more sensitive, and in any case, proper methods and appropriate tools are required.
In the process of storage and installation, the bearing parts cannot be damaged.
Some bearings require greater pressure pressure, so special tools are needed.
Be sure to refer to the car manufacturer's manual.
5  When installing the bearing, it should be in a clean and tidy environment. Small particles into the bearing will also shorten the service life of the bearing.
It is very important to keep a clean environment when changing bearings.
Before installation, check the condition of the shaft and bearing seat. Even the slightest wear and tear can lead to improper coordination, which can lead to the early failure of the bearing.
6  For hub bearing units, do not attempt to disassemble the hub bearing or adjust the sealing ring of the hub unit, otherwise the sealing ring will damage the entry of water or dust.
Even the seal ring and inner ring are damaged, resulting in permanent failure of the bearing.

There is a magnetic thrust ring in the sealing ring of the ABS bearing, which cannot be bumped, impinged or collided with other magnetic fields.
Remove from the packing box before installation and keep them away from the magnetic field, such as motor or power tools used.
When these bearings are installed, the ABS alarm needle on the dashboard is used to change the operation of the bearing.

A hub bearing with ABS magnetic thrust ring, to determine which side of the thrust ring, can be used with a light small thing near the edge of the bearing, and the magnetic force generated by the bearing will attract it.
When installed, the side of the magnetic thrust ring is pointed inside, and the sensitive element of ABS is being installed.

Many bearings are sealed, and such bearings do not need to be greased for the whole life.
Other non-sealing bearings such as double row taper roller bearings must be lubricated during installation.
Because of bearing inner cavity size is different, so it is difficult to determine how much oil is the most important is the guarantee of bearing grease, if excess oil, when bearing rotation, excess oil will seep.
General experience: at the time of installation, the total amount of grease is 50% of the clearance of the bearing.

The size of the torque varies greatly depending on the type of the bearing and the bearing seat
