Make sure your drag link is adjusted properly... If you are having to hold the wheel to the right, loosen the the sleeve on the drag link and rotate it "up" to turn your wheel to the left. I would start with some what bold adjustments and then dial it in, maybe a 180 degree turn, then take a little out or a little more to get it perfect.

But if you never got an alignment or messed with the drag link after your lift it could be the problem, all that should be need is the drag link adjustment, no need to take it in.
