I am looking for a shaft assembly for my 94 F150 4X4 with a 5.0. I am looking for the inner shaft, the u-joint and the outer shaft. Whenever I talk with a parts guy, they come up empty. I'd like to get all three as an entire assembly or all three parts separately. I'm looking at my Chilton's book and the numbers in the old diagram are 3219 for the right hand side, which is what I need.

I had put on new u-joints, it felt sort of tight in gear, then snapped the axles at the ujoint!

I need a part number or the best way to search for it/them.

Thanks!!!
