Bearing is a very important part in the car. In order to assure your safety and the car’s reliability, you should check the wheel hub bearings regularly no matter how old the car is. Today, I will tell you some matters needing attention about bearings.

Notice if the bearing has the early alerting signal of abrasion: friction noise during the rotating process or abnormal speed reduction of suspension combination wheels while making a turn.

If you hear noise from wheel hub bearing part, then first find the location of the noise.

Suggest you replace the bearings in pairs even there is only one bearing damaged.

The wheel hub bearings are very sensitive, so you’d better use correct method and proper tool under any cases.

Bearing installation should be in clean and neat environment. Even the entrance of a tiny particle will shorten the service life of bearings.

Do not disconnect the wheel hub bearing or adjust the seal ring of wheel hub units, or you may damage the seal ring or result in the entrance of dust.

As for the wheel hub bearing installed with ABS magnetic thrust ring, improper installation may result in function failure of braking systems.

When you install the lock nut, because of the difference of bearing type and bearing block, the size difference of torques may be very large.
