If your looking at the back of your car on the passanger side you will find a 3/8 square bolt to the front of the rearend all you do is take a ratchet no socket and take the bolt out fill it tell it starts to run out put bolt back in and and your done as far as filling it.. if your going to change the fluid then you have to take rearend cover off get a gasket from autozone and some ornge rtv clean cover and rearend really good with brake cleaner put rtv on rearend and cover put gasket on cover side put cover back on tork to specs let rtv dry a couple hours, i let mine dry overnight fill and your done make sure you put the right rearend fluid in and if your car has posi you need an aditive that you put in first before the gear oil comes in a little tube ask some on at your local parts store hope this helps
