The front traction bar ties into the front cross member, which is bolted to the frame. I'm guessing that either your frame is bent, or your cross member is bent. Either get them straightened/replaced, or if you take apart the front traction bar, you will see that the washers that hold it in rest against a ledge on the traction bar. If you grind this ledge back and thread the rod farther, you will bring the front wheel forward.
You can also cut the traction bar and take a piece out, but that is a little more obvious and I would tend to avoid cutting a structural suspension component.
