That driveshaft is too short, causing this problem. I would pull that bushing , install new if it fits tight and get a longer driveshaft.

Thanks for the reply. That pic might be deceptive cuz the front of the car is way up in the air. The shaft has roughly 3/4" of travel.
I agree with the others. 3/4 inch movement is fine, but that yolk is sticking way out the back of the tail shaft. Gotta wonder how much spline engagement there is. Good thing you found this before it blew apart on the road.
I have mechanical Aptitude. I can screw up anything.

I think you will find the bushing is siezed on the yoke. Why does the yoke look black and rough when I blow up your pic? You didn't paint or undercoat it did you?
In theory, there is no difference between theory and practice. In practice, there is.
