For what it's worth.
I put new Hankook 19. 5s on the truck, and had a strange 'floating' steering problem, as well as odd pull. But when I equalized the pressure in the front tires, that problem went away.
But I still had 'bump steer' that would happen whenever the camber of the road changed, or the front tires would hit chuck holes. Turns out a stabilizer link was shot (ball was dislocated and wore away 1/8" of metal on the face of the socket). I replaced the links (they only went 215K miles until visual failure; Detroit still can't make anything that will last
) and most of the bump steer problem is gone.
I was surprised that the stabilizer would make that much difference in steering. But upon further reflection, it makes sense, since the track bar does weird things to the geometry, too; when the stabilizer isn't stabilizing, the track bar is working overtime.
I don't have a rear stabilizer, but I would guess that one would also help minimize steering problems, by preventing body/frame roll that makes the track bar do its thing.
