I refer to this as "crabbing". My VX did this A LOT before I lifted with OME 912s. Since then, the crabbing effect has been minimized. I suspect this is a feature of both our short wheel base frames and coil springs in the rear, as I have never experienced this kind of behavior in any other vehicle. On dirt roads that are badly washboarded I have this problem the most, travelling at 20-30 mph causes the VX to shimmy back and forth over the washboard.

I just did my center link, ball joints and tie-rods up front and I definitely notice a difference up front, but I am not sure how the front end would effect the bouncing and crabbing in the rear.
