My buddy was on his way from PA to SC and on the way this happened. I remember awhile back that the front cardon joint Gets old on the front drive shafts and causes vibration enough for the case to split? The hubs were not engaged at the time. Any other ideas?
Sorry for your friends misfortune. There is a thread on this a couple months ago on split cases. Apparently, Ford changed the fluid type to XL-12 I believe. Search and you will find lots of info.
What fluid was your buddy using? Mercon V? Question: If the hubs were not locked how can the worn out cardon joint on the front shaft be the cause?
At around 400k I started to get a rumble out of mine, drained the fluid and strained it through some blue shop paper towels and found a bunch of bearing/race chrome flakes in the fluid.
What kind of condition was the carrier bearing in?

Also he said the other night that it was vibrating badly long before it ever went. He would stop and see nothing wrong and kept driving. I find it hard to believe that the fluid could cause these to break

I personally am not sold on the merconV causing the issue either. There is no real evidence other than the one u tube video that was posted in this thread earlier. That being said its dirt cheap to buy 2 quarts of transfer case fluid from ford.
I bet he lost a bearing.
What year is the truck? Mine is a 2000 and as I said earlier I caught mine before it grenaded but it was on its way.
My comment about "loseing a bearing" should have read " lost a bearing in the transfer case"
Just spit balling but.....
Bad carrier bearing introduces small vibration in to the drive train directly affecting the out put bearing in the transfer case. The output bearing begins to lose the plateing on the race and bearing and all the metal gathers in the bottom of the case and bathes the front output bearing in grit accelerating its wear and generating heat. The front output bearing seizes and boom, Pics posted on FTE.
I have no idea if this scenario resembles reality but it makes sense to me.
