If the driveshaft has ever been pulled down for ANY reason such as; flexdisc, u-joint, center bearing, etc., it could very well have come apart at the spline accidentally and put back into place in the wrong position.
To maintain proper driveshaft balance, it should be marked before sliding the spline apart so that it could be put back in the same position. But, sometimes, they will come apart accidentally and no attention is paid to its original position when reassembling. If this is the case, you can pull it apart, rotate it 180 degrees and probably get much closer to proper balance. You might find paint markings that you can line up, or you might have to take it completely out and take it to a driveshaft shop where they can spin balance it and find the proper relationship of the two shafts. Good luck, |
