International 140 Transmission/rear end trouble

We have a International 140 (I believe it is a '73 model) that has some transmission/rearend trouble. About 5-7 years ago, we unhooked it from a wagon, pulled up then put it in reverse and things wen't downhill from there. When we tried to back up it was all jumpy and seemed like it kinda wanted to go forward and backwards at the same time. We hoped that it was just somehow stuck in two gears but no evidence of anything simple like that when we removed the transmission top plate. Well, we were busy then and we shoved it in the shed off to the side. Its sat there now for the last 5-7 years. I sure hate for an otherwise great running tractor to just rot away. So yesterday I took the top back off the transmission along with the PTO plate on the back of the transmission. I jacked it up and spun the wheels and when you spin just one, the other one spins the opposite direction and everything works smooth as silk. But when you spin the both in the same direction it obviously tries to spin the bottom shaft of the transmission and it sounds awful. Watching that lower shaft while someone spins it, the shaft rotates very roughly. No evidence of it moving up and down or side to side, it just it just rotates hard (kinda like start, stop, start, stop, start stop. If that makes any sense.) The noise it makes is almost like if you let out on the clutch without having it all the way in gear..like a grinding noise. Anyhow, I'm thinking it something to do with that bottom shaft. Maybe one of the bearings is out? But then again, there is no obvious looseness to the shaft. Do you have to split the transmission away from the engine to get to that front bearing? Or does anyone have any ideas as to what the problem might be?
