Never changed commodore diff oil, but a few other cars. There should be a couple of plugs in the actual diff case/housing, whatever you call it. Have a look, one fills the other drains.

Yep.. Undo the drain plug and then pump the new oil in the filler plug.. I'm pretty sure you need an oil pump though..

No harm changing the diff oil as it gets old with time

well you can just undo a few of the bottom bolts and it should start to drain out, when its stopped dripping do them up again, take out the bung with probably a qtr drive and put the new oil into it, the oil level should be up to the level of the bung, so its will leak out but not pure out, just level with it... make sure the car is level while doing it.

worst thing for diff oil is water... when driving the diff gets fairly warm, then if you will acroos a floodway with like 1 foot of water, your diffs cools... causes a vacum and sucks water in through the diff housing air breather.... can suck water in through the wheel bearing seals too...

What sizes are the drain and filler plugs ?
