On the lower passenger side of the diff, there is an oil drain screw (6 point, female hex, impossible to miss). Per the WIS, take it off and throw it away. While the oil is draining clean the new oil drain screw and put a little sealant on the threads. When you're done, do the same with the new oil filler plug. With the diff empty, clean the threads on the drain hole and install the new drain screw. Move to the driver's side of the diff there's an oil filler screw that sits a little higher. Yes, that one gets thrown away too. Add 1.1 liters, clean the threads on the filler hole, and install the filler screw. Both the drain and filler screw should be torqued to 50 nM (37 lb/ft).
Some people reuse their drain/fill screws. They're part number 0009976232, and cost $2 each.
