Well I don't have full time 4wd, it has a NP205 and I can shift between 2 and 4wd. But the 80w90 gear oil in the transfer case is so thick that the front output of the transfer case still spins even when not engaged... Of course it doesn't have enough power to spin the wheels like this, but nonetheless, it will still spin the driveshaft, thus moving the parts in the differential. That 80w90 oil is some thick stuff!
