wheel bearing

Upon completion of all parts meet the requirements, the inner bearing grease after release hub.

When grease the bearing cavity attention should be squeezed into the bearing grease until grease to date to emerge from the other side of the bearing. In the hub and shaft Double Row Ball Slewing Bearing‍ cranial cavity Apply a thin layer of grease to make it play a role in rust. Note that the hub cavity do not apply too much grease, otherwise it will affect the cooling and braking.

The hub and the outer bearing back onto the journal, hand-axis head adjustment nut, and then use the required shaft torque wrench to tighten the adjustment nut. After tightening the nut, turn the wheel a few times to be around to see the bearing installation; on the other hand, by turning the bearing and seat properly fit. At this time bearing tightness appropriate wheels to rotate freely and not feel the axial clearance.

Finally, in order to install the locking plate, fixing nut, tires, dust cover and decorative cover and other parts.

Wheel bearings adjusted, with some marine crane bearing‍ mileage (about 1Okm), stop and check for swab touch wheel temperature, if fever, is caused by the bearing adjustment too tight, should be re-adjusted appropriately relaxed bearing tightness.

Non-normal wheel bearing damage causes

In the repair process, often found that some cars have a greater driving noise, no abnormal tire wear inspection, turn the wheels on the lift no abnormal sound. This phenomenon is often caused by abnormal wheel bearing damage caused by the so-called non-normal means of bearing damage caused by the installation of. Automotive wheel bearings are generally double row ball bearing, at the time of installation of the bearing installation if you use a hammer percussion, or when the bearing is installed into the bearing inner race of the bearing by pressing installed, thin wall bearings‍ will cause one side of the bearing raceways damage. Noise when the vehicle is traveling, and when the wheelie is better since the raceway side, and therefore noise was heard. Correct installation operation is the key to long life bearings.
