JD 2210 4 wheel drive locking up in reverse

[peppilappu]

I heard definite grinding the last week when I operated the 4 wheel drive in reverse. Then the front wheels started locking with the rear wheels pulling them.
So at first I thought it was the front diff. Since I hadn't changed the front axle oil ever (429 hours). I emptied the gear oil and their was shavings so I tore it totally down and after inspection noticed very sloppy engagement so I replaced the front diff.
Seems to be much smoother, no backlash and very tight. So front end is totally good now.

Put the thing back together thinking I found the issue but the problem still existed. Now I know its in the rear transmission. Specifically where the 4 Wheel gears mesh when engaged. No issues in 2 wheel, only 4 wheel in reverse. Started tearing down the entire body to get easy access the tranny. Cleaned it all ready to get into the guts of the thing.
Does anyone have a part diagram showing the gears in the JD 2210? I don't want to replace the entire tranny, I think its a bad gear set that powers the front wheels when engaged.

Thanks in advance.

Just a quick update for those that have this problem. I found the issue. both front axle shaft bearings had shattered.
Had to pull the tranny out of the tractor and tear the front half down to get to the broken parts:
2) JD # CH10564. Replacing the snap ring 40M7225 and bushing M80897 because they were mangled a bit. Gears were good.

TOTAL REPAIR COST. $30.70 including shipping for the parts. Labor of course was done by me.
Just saved $5K.. Yep, I'm proud.

Good job, peppilappu! Feels good to fix it at such savings I bet!
