Default rearend fluid help!

I did a lot of searching on a couple of boards for the last 30 minutes and I am having trouble getting the info I want.

I plan to change the fluid in my rear since I want to test and see if it will help with all the loud noise that is coming from the rear. I can't really describe the noise, but it is kinda like a da..da..da...da..da...da..but kinda in a exhaust gargle (but not) sound. Does it when accel or deccel, but not all the time, just most of the time. Anyway, What I want to know is

1. What kind of fluid? How much fluid(I think I heard 3 quarts or something)? I think I have a torsen, but I don't know how to find out. It is a 99 Z28.

2. How do I change the fluid? I saw a write up on installuniversity, but that includes replacing the cover. I just want to drain and refill. Do you drain and refill with the aftermarket cover the same way with the factory one?

3. Should I take off the cover and see what everything looks like in there? Since it is making noise and all!! Can you just reuse the factory gasket, or do I need to buy another once I take the cover off?

I think that does me. Thanks for any help!!
