Roger that, see the piece from web. As I said, mine does not move any. If drive shaft is balanced, new joints, double checked, phased, rotated 180 deg and rerun, then it is NOT the drive shaft unless it's female spline is worn... I believe it would move a little with DS removed and should be pretty tight with DS installed.
