Default How to change diffy fluid

I tried a search and can't find clear insturctions on how to change the diffy fluid. If it is not too difficlut, I am thinking this is something I might do annually considering some of the issues that arise with the Vette diffy. Is there a diffy fluid that is better than the others?

the manual tranny fluid change is straightforward, here's a link w/ pics to see the fill plug, http://forums.corvetteforum.com/show...erential+fluid , the drain plug is on the opposite side of the fill plug, place a large pan under the drain, you can use a 3/8 ratchet without a socket to unbolt both plugs, you will need a hand fluid pump to re-fill, just be sure to have the car level when filling, you can also do the differential while your down there.

Choice of oils are plenty, amsoil, royal purple, mobil, redline, to name a few, I went with royal purple for the tranny and diff. with good results

Thanks guys. Great info. From now on, I think I will be changing my Diffy, manual tranny and clutch pedal fluid once a year.
