In the process of maintenance, often find some cars have bigger noise, check tire no abnormal wear and tear, no sound in the lifting machine rotating wheels. This phenomenon is often caused by wheel hub bearing abnormal damage, abnormal refers to the bearing damage due to installation. Car front wheel bearings are generally double row ball bearing, if you use the hammer knock when install the bearing installation, or when the bearing is installed into the bearing installation, by means of the pressure bearing inner ring can cause side bearing raceway damage. When the vehicle noise, and when the wheel off the ground because of race a better side, so can't hear the noise significantly. The correct installation operation is the key to long bearing life.

Wheel hub bearing (hub bearing) is the main function of bearing and provide accurate guide to the rotation of the wheels, it was under axial load and bear radial load, is a very important component. Traditional car wheel with bearing is combined by two sets of tapered roller bearings or ball bearings, and the installation of the bearing, oil seal and clearance adjustment is carried out on the auto production line. This structure makes it in the car factory assembly difficulty, high cost and poor reliability, and when the car in pits maintenance, also need to clean, oil bearing and adjustment. Wheel hub bearing unit is in the standard angular contact ball bearings and tapered roller bearings, on the basis of it will be two sets of bearing as a whole, has the assembly clearance adjustment performance is good, can be omitted, light weight, compact structure, large load capacity, for the sealed bearing prior to loading, ellipsis external wheel grease seal and from maintenance etc, and has been widely used in cars, also in the trucks.

In the use of the wheel hub bearing and install please note the following items:

In order to ensure maximum security and reliability, it is recommended that you no matter how long vehicles will check regularly whether the wheel hub bearing, pay attention to the bearing wear of the early warning signs: including any rotating friction noise or hanging abnormal combination wheel in turn. Suggestions to rear wheel drive vehicles to 38000 kilometers is the vehicle for front wheel bearing lubrication. When replacing the brake system, check the bearing and replace oil seal.
Hear the wheel hub bearing area of noise, first of all, it is important to find the location of the noise occurs. There are many possible noise of moving parts, may also be some rotating parts and no contact with rotating parts. If confirmed is the noise in the bearing, bearing may have been damaged, need to change.
To prevent on both sides of the bearing failure because the front wheel working conditions are similar, so even if only one bearing is broken, also recommends replacement in pairs.
Wheel hub bearing is more sensitive, under any circumstances need to use the right methods and with the right tools. In the process of storage and transportation and installation, bearing components cannot be damaged. Need some bearing larger pressure into, so I need a special tool. Be sure to follow car manufacturing instruction.
When installing the bearing should be clean and neat environment, tiny particles into the bearing will shorten the service life of bearing. Replace the bearing when it is very important to maintain a clean environment. Not allowed to use hammer percussion bearing, pay attention to the bearing don't fall on the ground (or similar misconduct). Before installation should also check the status of the shaft and bearing seat, even minor wear can also lead to cooperate, that cause of bearing early failure.
Don't attempt to disassemble the wheel hub bearing or adjust the wheel hub unit seal, otherwise it will make the sealing ring damaged cause or dust into the water. Even the sealing ring and inner ring raceway damage, permanent failure of bearing.
Equipped with ABS device sealing ring with a magnetic thrust bearing ring, the thrust ring is not influenced by the collision, impact, or a collision with other magnetic field. Take out from inside the box before installation, make them away from magnetic fields, such as using the motor or electric tools, etc. When installing the bearing, through the road test observation on ABS warning needle dashboard, to change the bearing operation.
Equipped with ABS wheel hub bearing of magnetic thrust ring, in order to determine the thrust ring pack what side, use a light small things * close bearing on the edge of a bearing produced by the magnetic force will be attracted to it. When installation, pointed to one side of the magnetic thrust ring, is sensitive element for ABS. Note: incorrect installation may lead to the function of the braking system failure.
Many of the bearing is sealed, this kind of bearing in the whole life period is not to need to add grease. Other not sealed bearing such as double row circular cone roller bearings must add grease lubrication 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. Experience in common: during installation, the amount of grease to account for 50% of the bearing clearance. 10, installing a lock nut, due to the different bearing types and bearing torque size difference is very big.
