1, hanger bearing damage reason is lack of lubricating oil in the bearing, so that the bearing wear or ablation and the loose kuang, or because of disrepair, bearing outside diameter and the hole turn loose kuang, bearing periphery of the aprons break or fall off, form the shaft within the melt frame beat, which use a lower fracture, fracture and broken at bolt connecting bolt, etc.

2. The damage of transmission shaft components is caused by the deformation of front and rear transmission shaft, universal joint uranium fork, joint flange fork and telescopic joint keyway shaft, resulting in axis wobble in the transmission of the whole set of transmission shaft; Or field universal joint lack of lubricating oil and too much wear loose kuang; Or due to the expansion joint between the sliding keyway and groove increased wear and relaxation. So that the whole set of transmission shaft in the transmission of the increase in the amount of voids and axis vibration, the center of the suspension by its impact for a long time and the lower part of the fracture.

3, the center of the truck drive shaft hanger, in the warranty installation of the center hanger due to the improper fastening bolt method, not balanced uniform installation hanger or assembly hanger cover, so that the hanger or hanger cover warped, a point of stress concentration and fracture, in order to cause the hanger broken.

As long as there is one of several factors that cause the damage of the central hanger of the transmission shaft, it will cause inestimable loss to the vehicle. For this reason, the vehicle regular maintenance or warranty should focus on the transmission part of the inspection and adjustment.
