A little update to this.
I pulled all the 3" Rough Country lift off and replaced it with 2.5" Carli stuff (coils, trac bar, shocks). Had it re-aligned after the new lift and all my previous issues are gone.
One of the big thoughts was that it was related to slop in the steering box. It never got any worse, and now that it is corrected, disproves that theory.
Perhaps it was the angle of the pitman arm. Maybe 3" is too much, and it needed a drop bracket.
Anyway the truck is aligned with perfect specs now. It tracks perfectly, and I couldn't be happier.
