Its been many moons ago for me also but the only weakness in the tractor we changed was after several failures in the rear end ring and pinion finally had a tip from someone to find a complete third member from another 4166 from the front diff. And use in the back diff.and change rear driveshaft length. It involved the front usage and extra pinion support bearing that the back did not.
