I own a 88 Jeep Cherokee 4W drive. My question is, " how many wheels are actually driving when I'm in 4W drive?" I know for a conventional(i.e. open) rear differential, only one wheel drives. When I place my car into 4W drive, the vacuum motor connects both shafts in my front differential. I assume this gives me two driving wheels up front and one driving wheel in the rear for an actual 3W drive vehicle. Am I correct in this assumption? Therefore in order to get a true 4W drive vehicle, I need to add a locker or limited slip differential in the rear. If this a correct assumption?
