What happens if a drive shaft vibrates?
Driveshafts are finely balanced before installation to ensure they do not vibrate. Any sort of vibration indicates an issue. An excessively vibrating driveshaft will not only cause vibrations that can be felt by the passengers, but it can also cause accelerated wear on other drivetrain components.
What should I do if my driveshaft is out of balance?
If driveshaft is suspected of being out of balance, check for missing balance weights, broken welds and any build up of dirt or paint that could cause the driveshaft balance to be affected. Inspect U-Joint and clamps for wear or looseness, replace if required. If the driveshaft is bent, it will have to be replaced.
What does it mean when the drive shaft is unbalanced?
In this case, it could mean that the bearings have worn out so much that they allow a wider than usual movement of the transmission shaft, coming out of its axis. Even though the sensation of an unbalanced wheel may be similar, it will be much more frequent, as the rotations of the drive shaft are 3-4 times faster than those of the wheels.
