1997 BW4404, lost VC?

[Four0Sport]

My 93 is at a friends house about an hour away getting a front bumper made, so in the meantime im driving my 97 V8 AWD. Well, while my lifted 4x4 is away, we get ~16" of snow between 2 storms and im driving the AWD Explorer. No problem, right? I fishtail everywhere, can barely make it up a snow covered road, spin out from the rear constantly. I was attributing all of these to crappy tires but when trying to pull up a friends driveway this afternoon and spinning the rear end back and forth he yells 'your front tires arent spinning!'. We make it home and I have my fiance get a safe distance in front of the truck while I apply the brake and ease into the throttle. Both back tires spin, but I get nothing from the front.. slowly release pressure on the brakes, back wheels still spin and the fronts arent grabbing at all. Only movement I get is from the truck slowly inching forward.

Back in December I got the truck stuck at a friends house during another big snow and I can remember poking my head out the window and seeing the dr side front wheel spinning. I rocked it back and forth a few times and when I didnt get anywhere I left the truck so I wouldnt tear it up or his yard anymore than I did.

So.. any ideas? I've been reading threads on the BW4404 all afternoon/evening and the thing that keeps hittin me is maybe I lost the VC from the fluid getting hot? leaking into the t-case? IDK.
