In the use of wheel bearings and installation, please note the following:
1, in order to ensure maximum safety and reliability, it is recommended that you regardless of the length of time should always check the wheel bearings - bearing attention to whether there is early warning of wear and tear: including any rotation of the friction noise or suspension combination wheel in turn When the normal slowdown. For rear-wheel drive vehicles it is recommended to lubricate the front wheel bearings when the vehicle travels to 38,000 km. When replacing the brake system, check the bearings and replace the oil seal.
2, such as the wheel hub bearing parts to hear the noise, first of all, it is important to find the location of the occurrence of noise. There are many possible moving parts of the noise, it may be some rotating parts and non-rotating parts have come into contact. If it is confirmed that the noise in the bearing, the bearing may be damaged, need to be replaced.
3, because the front wheels lead to failure on both sides of the working conditions of similar bearings, so even if only a bad bearing, it is recommended to replace pairs.
4, wheel bearings are more sensitive, in any case need to use the right methods and the right tools. In the storage and installation process, the bearing components can not be damaged. Some bearings require a greater pressure to press, so special tools are required. Be sure to refer to the automobile manufacturing instructions.
5, the installation of bearings should be clean and tidy environment, the small particles into the bearing will shorten the life of the bearing. It is important to maintain a clean environment when replacing bearings. Do not use a hammer to knock the bearing, bearing attention not to fall to the ground (or similar improper handling). The shaft and bearing housing should also be inspected prior to installation, and even minor wear can result in poor fit, leading to early failure of the bearing.
6, the wheel hub bearing unit, do not attempt to open the wheel hub bearing wheel bearings or adjust the ring, otherwise it will damage the seal lead to water or dust into. Even the raceways of seals and inner rings are damaged, resulting in a permanent failure of the bearing.
7, fitted with ABS bearing bearing ring has a magnetic thrust ring, the thrust ring can not be impact, impact or other magnetic fields with the collision. Remove them from the box before installation, keeping them away from magnetic fields, such as the motor or power tools used. When installing these bearings, observe the ABS alarm pin on the instrument panel to change the bearing operation.
8, equipped with ABS magnetic thrust wheel hub bearings, in order to determine the thrust ring mounted on which side, you can use a small thing close to the edge of the bearing, bearing magnetic force will attract it. Install the side with the magnetic thrust ring pointing inside, is on the ABS-sensitive components. CAUTION: Incorrect installation may result in failure of the brake system.
9, many of the bearings are sealed, these bearings do not need to add the entire life of the grease. Other non-sealed bearings such as double row tapered roller bearings must be greased during installation. As the bearing cavity size is different, so it is difficult to determine how much oil, the most important thing is to ensure that the bearings in the grease, if the grease too much, 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 bearing clearance.
