What are the symptoms when drive shaft damaged

1. When The sudden change of speed in the driving of the car, or the drive shaft make metal knock,it mean that some flanges or universal joints have worn too much and need to be replaced.

2. The drive shaft has a "clang" sound or noise disorder When the car starts or drive shaft made a clattering sound When the car backed up on a gentle slope,it meand bearing needle has broken or broken, and needs to be replaced.

3. The driving-shaft makes a distinct metal clatter, and it is more pronounced when the car is in high gear When the car starts or shifts gears.In this case, it is highly likely that the interference fit between the inner ring of the center support bearing and the shaft is reduced, resulting in loose and abnormal noise.

4. The drive shaft always has "clack" abnormal sound, and accompanied by vibration when The car is starting or moving.it mean that the fixing bolt of the center support bearing is loose.

5. There was a clear, rhythmic metal thump on the drive shaft when the car moves at a low speed or there is a clear sound when the car is sliding out of gear.The reason for this is that the compression force of the center support bearing shell is too large, so that the bearing can not rotate flexibly.

6. The sound of the drive shaft increases with the increase of the speed when the car moves,or center support bearing produces dull and continuous muddy sound.It shows that the middle bearing is loose due to wear and need to be replaced.

7. The sound of the drive shaft is disorderly and irregular, and sometimes there is the sound of metal collision when the car moves. It mean that the universal joint forks at both ends of the drive shaft are not in the same plane, so that the constant velocity arrangement is destroyed.

8. There's an abnormal sound in the drive shaft when the car moves at high speed, and Abnormal sound of transmission shaft still exists when taking off gear and sliding.This situation is most likely to be the center support bearing raceway damage, or the center support bearing was installed deviation.
