^Yeah those are nice if you can find one that you can fit into that area down there. I just did mine yesterday and found the amsoil pump to work great. It fit on the bottle perfect and has a big hose to pump the fluid in quickly.
I'd also recommend to anyone who hasn't changed theirs or don't know if it's been changed to change it! Mine was nasty!

Ha...what are you talkin about, a cup a day will make you a MAN! Kinda makes you want to change it more often than 30K though. That stuff looked like malasis pouring out of there and the magnetic drain plug had so much crap on it the thing barely wanted to come out of the hole....
Even though that Amsoil severe gear oil should last a long time I'll probably change it again sometime just to get the metal shaving out. Same with the tranny.

The OP needs to edit the DIY to mention loosening the fill plug first before removing the drain plug. It is better to be safe then sorry.
Also, I think 75w-90 gear oil will work. I got the Amsoil synthetic 75w-90 oil. I need to buy a couple more jack stands so that I can have the car fully lifted before I do my diff oil change.

Thanks guys for pointing out to loosen the fill plug first! Thats why this forum is the best!
I have a 2006 6mt g35 coupe with about 63k on it, today i did a list of things on the 60K service list and decided to do diy on the rear differential change. I hope this is somewhat helpful to someone.
What you will need:
3 quarts of 80w-90 gear oil (not synthetic, just plain gear oil)
Fluid pump.
10mm hex bit to loosen drain plug and fill plug
3/8 drive ratchet and small extension
make sure you have your front wheels higher than than the rear to make sure all the gear oil possible can get out.
FIRST LOOSEN YOUR FILL PLUG TO MAKE SURE YOU DONT DRAIN YOUR FLUID AND NOT BE ABLE TO GET THE FILL PLUG OUT Then you loosen your drain plug, the bottom one and once it is loose make sure you have a catch pan or bucket that can hold at least 4 quarts of fluid. Once you brake the bolt loose you will need to unscrew it the rest of the way by hand to make sure you don't drop it in your bucket! Once the plug is out and the fluid is draining take a min to look at your plug, it should be a magnetic one and just look to see if there is any metal shavings on it. If there is have it checked. It will take a good 10 15 mins for all the fluid to drain out.
Replace your drain plug back and make sure is tightened down real good, some replace the washer i did not do so. I also took some brake cleaner and cleaned up around the drain plug so i could watch to see if there were any leaks while filling the case back up. Let your front wheels back down to where the car is level for the next step. This will insure you are putting the correct amount of gear oil back.
Remove your fill plug located to the right and above the drain plug. Use your fluid pump to start pumping your 80w-90 gear oil back into the differential. Some say it holds 3 quarts, mine was just a little less. I was told by the service department to fill it up until it starts to slightly drain out the fill plug hole. Once that's done, replace your fill plug and clean the area with brake cleaner again. With my car on jack stands i started my car, put it in first gear and let it run for a couple of mins while i watched leaks, and listened for anything out of the ordinary.
Hope this helps guys and sorry no pictures i couldn't get the damn things to load right.

Yes, for diff oil you can use Amsoil 75w-90 Synthetic. That is what I bought and others have bought as well.
