Did you install the new servo? If so there's a couple of things to check. First make sure the servo is adjusted correctly before installing. There is a little score mark on the shaft. It needs to be pointing straight up. Second make sure the slider bar in your diff is slid all the way to the passenger side. That's 2WD and where you need to be before putting the servo back on.
