If you had it done 4 days ago, do you trust the guys that did it, and it could just be your rack in pinoin best thing to do is have someone else drive it around that has gone through the same problem

Well I can't give you the magic awnser you got me baffled as well, and what I was saying earlier was does it do it when braking over bumps in the road turning the wheel so far certain speeds that kinda stuff will help as well

Glock I don't remember what wheels you have. Aftermarket or stock? If they are aftermarket are they "hub centered" or just centered by the lug studs? You have changed the instant center of your ride. Some adjustment to this change may be in order. All of these trucks are a little different even though they appear to be the same. The natural settling of the suspension ie, control arm bushings, springs even the rear spring factory mounts will settle in just a bit due to frame settlement. How is your tie rod angle vs your control arm angle? Sometimes more to consider. Could be a simple solution. Just back up a little and look at each piece until you see the smoking gun. Sorry no pun intended.

Your before & after numbers appear to be identical. Could you scan your printout & post it up? Or maybe a pic?

Is the wobble you're trying to describe what we call "death wobble"? That's usually caused by worn out parts, or not enough caster, or terrible steering/suspension geometry. I'd ALSO recommend a switch away from twin-tube shocks to mono-tube shocks, no matter what. Problem is, they are harder to find, and cost alot more. BUT, they really are that much better.
