Don, I am looking at your pics and I think the rear shackle is suspect, with the angle you have on it, as the suspension goes into jounce the shackle is going to start to go horizontal quickly, expecially with the weight of the bed over it.

If your shackle is going horizontal it can do all kinds of funny things to the rear axle, expecially if it happens on one side of the truck and not the other, including not allowing the axle to go into rebound because it holds the spring temporarily in the flattened position, thus causing a misalignment side to side.

I bet if you move your shackle hanger 1.5-2" back it will help signifigantly.
