That happens to me as well. I just installed the rancho 9000 a couple months ago, and it does the same as the stock shocks did. On the way to work there is this seam on the bridge that connects to the on ramp, and the vx always hopps to the left (right handed turn right over the seam). the first time i did it, scared the crap outa me, because i thought something broke underneath! But I have noticed that trucks infront of me hop to the left as well when they drive over it...

I dont know.. I sorta like "forcably" doing it!
