Abstract
A process for balancing a vehicular driveline including a propeller shaft and an input shaft of a vehicle axle interconnected by a universal joint. First, the vehicle propeller shaft is balanced to a predetermined residual imbalance having an imbalance vector angle of 0° or 180° which lies inline with open set of cardan joint trunnions. The corrected residual imbalance is then visually marked. Next, the input shaft is balanced to a predetermined residual imbalance having an imbalance vector angle of 0° or 180° which lies inline with cross-holes in yoke ears. Again, the corrected residual imbalance on the input shaft is then visually marked. During the assembly of the vehicle, the assembly line operator couples the propeller shaft to the input shaft through a cardan joint cross by aligning the marks on the propeller shaft and the input shaft so that the marks are located opposite to each other.
