A method for making a hybrid yoke for a vehicle driveshaft assembly comprising:
- pre-forming a cast iron portion having a first end and a second end, the first end having a pair of opposed yoke arms thereat;
- placing the cast iron portion into a mold defining a shaft-receiving position of the hybrid yoke;
- and
- pouring molten steel into the mold to form the shaft-receiving portion having a yoke end and a shaft end, the shaft end for coupling to the driveshaft assembly, and wherein the yoke end and the second end of the cast iron portion cooperatively form an interlocking bond after solidifying.
