[Stocker]

I tightened mine the same way sethv did. I didn't think tightening the steering wheel nut had any effect on the wheel returning to center. The only time I experienced centering problems was when monkeying with the adjustment screw on a worn-out steering box.

Your 1" of lengthwise play sounds excessive but I don't know what might cause it. Mine has very little free play.

Sorry I wasn't more help.....
