Do you have the aluminum bearing inserts installed. Check them out and they should solve your diff problem. I have several gallons on my T with no F/C/R diff issues. I'd start looking for the problem. Also have you been shimming the rear diff when repairing. New parts should be allowed to "break in" for a few tanks before going full race mode on it.
