I'll bet it's still trying to move while running, but you can't hear or feel it easily with the engine running. If you can tell it's trying, that's a good sign.
Have you tried leaving the selector in 2H and making a lot of low speed, lock to lock turns in a parking lot? Try that while shifting between D & N to unload the transfer case while maintaining momentum.
