Seeing I already answered this very question to you in another thread and it wasn't rebutted chances are I may have been correct. I know, it is a long shot but sometimes when it comes to CJs I get lucky.
I did not like the shop in Ware that set up my Mosers the last time seeing how I had leakage and issues from the collars not being pressed on propperly.
The bearing on a 20 is dry, meaning it isn't lubed by the diff fluid so you must grease it. If oil got to the bearing and leaked out as you mentioned it's because of a faulty inner tube oil seal.
