I lost drive completely and suddenly at the track. I've gotten far enough into the box and thought about it enough to be pretty sure it's the input shaft. I'm about to open the diff next because I recall Todd Cook saying it could be replaced from inside.
Can someone point me to the diff drawings and whatnot that will give me a clue what I'm looking at when I find the culprit. And how to replace it and whatever collatoral damage there may be.
But mostly, to not sound entirely stupid if I need to call Scotty. <Which I will, but that's another story.>
TIA.
