Sounds like one problem may be that the steering box might have not be centered from lock to lock before the pitman arm was attached.

Also, was this a 3/4 to 3/4 or to 1/2 ton?

3/4 drum to 3/4 disc. we centered the pitman arm, still have the problem. any other ideas

I know you said it was aligned but the only other thing I can think of is that maybe the springs aren't properly seated.
