And then once it spun around and got to the bad part, the transfer case just sent all the power to the front (least resistance) and the front diff could not engage because the ring is jacked up.

That would explain why I see the front driveshaft spinning with no power to any wheels. And then why locking the center, I was able to move, because half of the power was sent to the rear.

Thanks for the help everyone. Hopefully the front diff is the issue. I am taking it back today.
