Ok, Just checked under my truck.
It appears my u-joint at my trans is trash as there is grease coming out of it and there is a little play in it. The rear by the pinion seems ok.

I took the angle finder to the bottom of the trans, DS, and pumpkin snout where the pinion gear goes into and I get as follows form my garage floor:
Trans: 1-2 angled up
DS: 5 angled down towards the pumpkin
Pumpkin: 2 angled down

What about the use of a double cardan joint?

With the grease on the u-joint, I believe they are bad, but I don't know what is needed to correct the driveline angle.

Any help is welcome!
