So I found a patch of snow turned out to be deeper then I thought and I ended up getting stuck. Luckily enough there was a tractor nearby plowing some snow so he came over to help. He hooked up to my hitch and tried pulling me backwards but it wouldn't budge and I couldn't get the wheel to spin in reverse eventho drive spun them no problem.

After I got stuck I put it in 4lo diff locked in reverse (according to the shifter anyways) and when I hit the gas, I could here things working but no tire spin. Almost like the transfer case didnt fully shift in to 4lo and was it neutral or something. However the wheels would spin in drive and dash indications were correct.

After the tractor pulled me out from the front, reverse worked fine so I don't thinks in the tranny but I don't know. And althought its cold out this issue happened after a 100kms (60miles) drive when everything was warmed up and working great.

I went for a little adventure today and everything work well so I'm hoping it was just a fluke
