The imbalance of the vehicle drive shaft, in the running there will be a periodic sound, the faster the speed, the louder the sound. In severe cases, it can make the body shake, the cab vibrate and the steering wheel feel numb. Due to the body shaking, will cause the vehicle parts of the loose, leading to accidents. Cab vibration, serious welding joint cracking.

Reasons for vehicle vibration include:

1, drive shaft bending

2. The flange and shaft tube of the drive shaft are skewed when welding

3, the middle support fixed bolt is loose

4, the middle support bearing position deviation

5. The universal joint is damaged and the installation is not up to requirements

6. The original balance block on the drive shaft falls off

The unbalanced driving shaft endangers the safety of driving. If the transmission shaft is out of balance, the following methods can be used to judge:

Jack up the middle and rear drive axle on one side of the car, start the engine, put it into high gear and observe the shimmy of the drive shaft. During the observation, note that if the rotational speed drops and the pendulum vibration increases obviously, it indicates that the transmission shaft is bent or the flange is skewed.

Drive shaft bending is shaft tube bending, most of the overload is caused by the car. The transmission shaft is seriously damaged due to overload and overhang. Although the middle support of the transmission shaft is strengthened and the strength of the flange fork is strengthened, the failure of fracture damage still occurs.

Replace the transmission shaft parts, straightening, balance should be checked, unbalance should meet the standard requirements. The technical condition of the universal joint fork and the drive shaft bracket should also be checked in detail. If the installation is not satisfactory, the cross shaft and the roller will be damaged and cause loose and vibration, which will also cause the drive shaft to lose its balance.
