Due to long-term high-speed operation, the drive shaft bends and makes abnormal noises when transmitting power.The middle support bearing of the transmission shaft is worn too much, the axial clearance and the radial clearance are enlarged, and it makes noise during the rotation.The cross shaft of the transmission shaft is worn or rusted and cannot rotate freely, and it will make a noise when the vehicle starts or reverses.

　　The spline of the drive shaft is severely worn, resulting in an excessively large gap between the gearbox and the gearbox, and abnormal noises may occur when power is transmitted.The intermediate shaft rubber is aging or the support fixing screws are loose, the transmission shaft makes abnormal noises during operation, and if it is not firm in time, the transmission shaft may fall off.For a rear-drive vehicle, the loosening of the connecting screw between the drive shaft and the reducer will cause the vehicle to make abnormal noises when starting or running at high speed.
