Abstract
An automotive prop shaft assembly particularly suited for coupling a transfer case to the front axle drive components comprises a tubular drive shaft having an initial uniform inner diameter relatively smaller than the outer diameter of a pair of forged insert yokes to be attached to the ends of the shaft. A section of each end of the tube is enlarged so that its inner diameter is sized to receive the yokes into the ends of the tube with an interference fit. The shaft and yokes are then welded together and weights fixed to the end sections to correct for imbalance.
