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.

1. A method for balancing a driveline including a first shaft and a second shaft interconnected by a rotating joint, said method including the steps of:balancing said first shaft to a first residual imbalance having a first imbalance vector; adding a first weight to shift said first imbalance vector so as to be disposed in at least one predetermined adjustment plane; balancing said second shaft to a second residual imbalance having second imbalance vector; adding a second weight to shift said second imbalance vector so as to be disposed in said at least one predetermined adjustment plane; assembling said driveline by connecting said first shaft to said second shaft through said rotating joint so that said first imbalance vector of said first shaft substantially offsets said second imbalance vector of said second shaft; wherein said at least one predetermined adjustment plane is defined by connection points for an end yoke connection of one of said shafts. 2. The method according to claim 1, wherein said steps of balancing comprise purposefully creating said first and second predetermined residual imbalances.3. The method according to claim 1, further comprising adding a mark indicative of a location of said first and second predetermined residual imbalances.4. The method according to claim 3, further comprising adding a first mark to the first shaft at the point of maximum imbalance and adding a second mark to the second shaft at the point of minimum imbalance.5. The method according to claim 4, first shaft is an axle and said second shaft is a drive shaft.6. A method for balancing a driveline including a first shaft and a second shaft interconnected by a rotating joint, said method including the steps of:balancing said first shaft to a first residual imbalance having a first imbalance vector; adding a first weight to shift said first imbalance vector so as to be disposed in at least one predetermined adjustment plane; balancing said second shaft to a second residual imbalance having second imbalance vector; adding a second weight to shift said second imbalance vector so as to be disposed in said at least one predetermined adjustment plane; assembling said driveline by connecting said first shaft to said second shaft through said rotating joint so that said first imbalance vector of said first shaft substantially offsets said second imbalance vector of said second shaft, wherein said at least one predetermined adjustment plane is defined by connection points for a flange yoke and companion flange connection.
