To change the lower case lube, undo the drain located at the bottom of the case and drain fluid. Above the drain port approx 6" there is another port. Remove that plug as well. Once the case is drained refill it by forcing the fluid into the bottom port. When it starts to come out of the top port it is full. Install drain plugs and you are done. You have to fill from the bottom to avoid any air pockets.
