I have a 2013 ram 2500 4x4 with 3 inch leveling kit. Just had the front end rebuilt new ball joints, tie rod ends, shocks, track bar, lower part of drag link. Took it in for alignment and the camber is out by a little over a degree. It had stock ball joints in it put stock ball joints back. Any ideas besides an offset ball joint?  Thanks in advance

Are you using the right length of control arms? It's possible that as the lift kit is pushing the axle down a bit more and rotating the axle forward changing the angles of the camber. 

 

Remember the lift kit not lifting the truck off the axle... It actually pushes the axle down away from the frame pivoting the axle forward as the axle drops. That pivot occurs from the length of the control arms. I would make sure the axle relation is like the factory height and not rolled forward.

I bought the truck March of this year the lift kit was already on tire wear was normal. I rebuilt the front end because of death wobble. Lower ball joints were worn.
