Right when he called out from above that the vibration was beginning they could feel it in the transfer case below. Then they put the scope in and heard a noise coming from inside the transfer case each time the vibration began.

So we are going to try flushing the fluid and see what we find out. Probably won't happen tomorrow though. No fluid in town.
