In order to ensure the dynamic balance of the drive shaft, you should always pay attention to whether the balance pads are unsoldered.The new drive shaft assembly is provided as a complete set. When installing the new drive shaft, pay attention to the assembly mark of the telescopic sleeve and ensure that the flange fork is in a plane.When repairing and disassembling the drive shaft, the assembly mark should be printed on the telescopic sleeve and the flange shaft in order to keep the original assembly relationship unchanged during reassembly.

　　The damage, wear, deformation, and loss of dynamic balance of the drive shaft components will cause abnormal noise and vibration when the car is driving, and will cause damage to related components in severe cases.When the car is driving, it makes a "Gordon" sound when it starts or accelerates rapidly, and it clearly shows the feeling of loose parts. If it is not for the loosening of the drive axle transmission gear, it is obviously that the transmission shaft is loose.

　　The loose parts are nothing more than universal joint cross bearings or steel bowl and flange fork, the spline shaft and spline sleeve of the telescopic sleeve.Generally speaking, the cross shaft diameter and the bearing openness should not exceed 0.13mm, and the meshing gap between the telescopic spline shaft and the spline sleeve should not exceed 0.3mm.The service limit should be repaired or replaced.
