Leaking 8 3/4

My 8 3/4 is leaking from the front where the driveshaft connects. I have heard SEVERAL diffrent was to fix it. They range from taking the rearend apart, messing with shims to just removing the bolts and putting on the new gasket. The leak is very small, however as we all know, it doesn't get better, it gets worse. Is this a repair I can do or will I need someone who has a LOT more knowledge than I? Any help would be appreaciated.
