Well, I replaced the leaf springs shackles and front shocks. The old nuts on the U-bolts were a son of a gun to remove. I had to use a 1/2 inch ratchet with a 3 foot cheater bar attached. Three hours later with a lot of wrenching they came off. I order new u bolts to find out they weren't the correct thickness or width. So I went to our local Bumper to Bumper shop and had two new made to the correct specs. The new parts went in easy as pie. I even installed the 4 degree caster shims that were not under the springs when I took it apart.
I dislocated my shoulder last weekend. So my cruise in my truck will have to wait. Of course I screwed up my right shoulder and can't shift the tranny with that arm yet.
I'll get back to you all when I get better. Hopefully I will tell you that it drives straight down the road.

I found my truck manual and noticed it said, The caster degree for my 3600 3/4 ton truck should be 2 degrees. So, I ordered them. Im not even gonna drive it. That was a waste of time putting those 4 degree shims in. I also got center pins for the leaf springs. So the shim will be one with the leafs. And they won't wiggle out from under them.
Lesson of the day, don't assume you know what you are doing! Check your manual first.
