Re: t-case problem.
Good thinkin Mikro, start with the basics duh, I was just jumpin a few steps ahead. Cause the same thing happened to a friend of mine only it didn't spin the front D-shaft, well not well anyway. The counter shaft's needle bearings were completely shot and it was wiggling around inside the case and screwing up all kinds of clearances. But his started making ginding sounds after a while or it was almost sort of a whiring sound. He had a bad leak at the rear output too and the case was low on oil, hence the bearings failing. Hope you just have a broken hub. Cause with a open diff and a broken hub that shaft will just spin in place doing nothing. Hubs easy and cheap to replace. T-case isn't.
