Please note the following items in the use and installation of the wheel bearing:
1, in order to ensure maximum safety and reliability, it is recommended you regardless of the age of the vehicle as long as to always check the wheel hub bearings -- pay attention to whether the bearing wear of the early warning signal: including any rotating friction noise or hanging combination wheel in cornering is not normal deceleration. The rear wheel drive vehicle is recommended to travel to 38000 km in the vehicle is to respond to the front wheel bearing lubrication. When replacing the brake system, check the bearing and replace the oil seal.
2, such as hearing the noise emitted from the hub bearing parts, first of all, it is important to find the location of the noise. There are many moving parts that may produce noise, and may also be some of the rotating parts that have been exposed to the non rotating parts. If the noise in the bearing is confirmed, the bearing may be damaged and need to be replaced.
3, because the front wheel leads to both sides of the working conditions are similar to the failure of the bearings, so even if only a bad one bearing, but also proposed to replace the pair.
4, wheel bearings are more sensitive, in any case, the need to use the right method and the right tools. In the process of storage and installation, the parts of the bearing can not be damaged. Some bearings require large pressure to be pressed, so special tools are required. Be sure to refer to the specification of automobile manufacturing.
5, the installation of bearings should be in a clean and tidy environment, small particles into the bearing will shorten the life of the bearing. It is very important to keep the environment clean when bearing is changed. Do not allow the use of percussion hammer bearing, bearing attention do not fall on the ground (or similar misconduct). Before the installation of the shaft and bearing seat to check the situation, even if it is a small wear will lead to poor coordination, which lead to the early failure of bearing.
6, on the wheel bearing unit, do not attempt to open the wheel bearing or adjust the wheel hub unit of the sealing ring, otherwise it will cause damage to the sealing ring led to the water or dust into the. Even the sealing ring and the inner ring are damaged, resulting in permanent failure of the bearing.
7, equipped with ABS device bearing sealing ring has a magnetic thrust ring, the thrust ring can not be impacted, or collision with other magnetic field. Remove from the box before installation, keep them away from the magnetic field, such as the use of electric motors or electric tools, etc.. When the bearing is installed, the ABS alarm needle is observed on the instrument panel through the road conditions to change the operation of the bearing.
8, equipped with ABS magnetic thrust ring of the wheel bearings, in order to determine which side of the thrust ring, you can use a light small things near the edge of the bearing, the magnetic force generated by the bearing will attract it. The side of the magnetic thrust ring is arranged at the side of the installation, and is opposite to the sensitive element of the ABS. Note: incorrect installation may result in failure of the braking system.
9, many of the bearings are sealed, this type of bearing in the entire life cycle is not required to add grease. Other non - sealed bearings such as double row tapered roller bearings must be lubricated with grease when installing. As the size of the bearing of the cavity is different, it is difficult to determine how much of the oil, the most important is to ensure that the bearing grease, if too much oil, when the bearing rotation, the excess oil will seep. General experience: in the installation, the total amount of grease to account for 50% of the clearance of the bearing.
10, when installing the locking nut, due to the different types of bearing and bearing seat, the magnitude of the torque varies greatly. Attention to the instructions.
