Take it on the highway. Same thing? Less or more? Road crown comes to mind right away.

 

thats were i notice it most is on the hiway.

 

should int make me feel like im just about to lose control. the slight movement of the steering corrects it. but its all the time

 

Ok. On to something. So it wanders a bit? Then when you correct it, it wanders again?

 

You've checked pressure and had it realigned. Did they check the thrust angle? Sometimes "in spec" and correct are two different things- and honestly with that gigantoid lift, even half an inch would make a huge difference with the blocks. Even with the alignment pins there can still be room to move. A lot of shops won't check the thrust angle unless you specify, or they check it quickly and move on if its in spec or close. Assuming they made sure there was no play in any ball joints and tie rods.

The other thing I can think is a tire issue. Rotate them around see if anything changes.

 

I see snow in your pics. Hammering a good size snow bank hard enough if its got some ice in it can be enough to knock your rear diff off track if it isn't torqued properly. It did mine in.

 

The caster is out there should be at lease a -0.5 degree split, so instead if left 4.7 and right 4.5
It should be like left 4.0 and right 4.5 to compensate for road crown

I had this problem on a 2005 Chevy Colorado. I couldn't get it to stop pulling no matter what I did. I put new tires on it and that solved the problem. I could tell the difference before I got out of the parking lot at the tire place. About a year later I rotated the tires and the pull came back. Damn!!! I re-rotated the tires back to their original spots and the pull went away again. I never rotated those tires again.
Rotate your tires. It's worth a shot.
