If your VX is lifted, then by the direction of the shift in the axle, I would say it is caused partially by the panhard bar. When the lift is installed the panhard bar drops at one end moving the axle to the right. Not lifted? Can't say for sure then, but maybe the panhard bar is bent...? I don't know if there is a cam adjustment for the panhard bar, but I doubt it... if there is though, it could be slid to the left. Don't know anything, otherwise
