I have a 2000 Chevy 2500 4X4 Crew cab old body style with a 4" rancho suspension lift. I have 35x12.5X16.5 BFgoodrich Mud terrains on it. Since I bought it I am have alignment problems. I just had the new tires mounted balanced and aligned yesterday. About a year ago a friend was following me and said my truck was tracking sideways down the road. I had it looked at and supposedly the left front of the frame was rolled in slightly. I was told this is not uncommon for this model. Is this true? The truck has never been wrecked and I have not taken it off road hard, matter of fact I have only been off road once sine I bought it 2 years ago. Not that I am afraid of damage I just don’t know where to go. I had the frame pulled by a body shop and aligned at that time. Supposedly it was good. The old tires were worn bad do to the alignment being out. So when I got the new tires I had them put it straight on the alignment rack and they could not get the camber on both the right and the left front to come in. the adjustments are maxed out. Blow you will find the numbers that the computerized laser alignment gave me. Could someone give there option and possible options?
Thanks in advance.

well three things come to mind:

1) 2500s have the front ends wider than the rears. Looking forward from one side of the truck makes it look like its driving crooked.

2) your frame is actually crooked

3) take the truck go a good 4wd alignment shop that deals with lift kits. Once the brackets are on, no matter what the lift says, its going to change the alignment specs. So some normally great shops can't align it because of the kit(even though they say "oh yeah, we can align it" or "itswithin specs").

This is what it sounds like to me (and I've seen it a few times in the shop). Someone brings in a lifted truck and we attempt to align it unless it has problems. Lifted trucks done RIGHT, we align all the time. If your torsion bars are cranked up too much, it will cause negative camber, and won't allow max settings to compensate for it. You might try cranking them down a bit and seeing if that helps. BUT if you do that you will lose some lift and your tires might rub.

How do your ball joints, bushings, idler arm etc look? When putting on the lift they are good things to replace. These parts maybe worn and then lift makes things worse.

Thanks For the replys. All the front end parts are good. Nothing worn.

Did some research and talked to a local 4X4 Shop. I ended up call Rancho and they told me not to use the factory setting instead the gave me the setting.
Camber should be -0.3* to 0.0* I am at -0.2 left and 0.0 right
Toe should be 0.1" plus or minus 0.2" I am at 0.08" Left and 0.09" right.
So I am good on both those. The issue now is caster,
they recommend Caster should be 4.5* plus or minus 1* I am at 2.3* Left and 2.6* right.
The local alignment shop says that they can't adjust the caster with out throwing Camber out what do you all think?
