If you are talking about the threaded sleeve on the lower a-arm inner mount, by centreing it you have moved the arm mount back toeing that wheel in. I'm guessing it is wearing on the outside of that tire? If you use a couple of long straight edges (better against the wheel but the tire will do) you can check the parallel and toe of the wheels to each other. That picture you took will do a lot for getting you back to where you were. Good pic BTW.
