I would focus on getting the rear end square with the frame, along with the rest of the suspension including the front wheels. If youve done this already then maybe the box isnt square on the frame.

I think I've read on here elsewhere where the wheels wont be centered front to back, but i thought they sat farther foward, dont remember for sure though, either way I would think that it would be relatively equal on both sides.
