Scott, that is the locker in the rear, and yes it can be if you apply the throttle at the wrong time. If I had it to do over again, I probably wouldn't do the auto locker in the rear since I drive up to 8 hours to go offroading, then again I only put 1500 miles on it last year, so I dont drive that much in the VX anymore. We will see how they pay off offroad before I make that call for sure with the hindsight.
