This really works, fill-er-up. Fill the oil cap completely full with gear oil than twist it on. Even if you don?t catch the thread perfectly and have to back twist you probable will not lose more than a drop or two. Believe me this is a lot easier than trying to fill the hub through the little hole in top. A full cap will top it off perfectly, its how they do it at the factory.
