I use Mobil 1 synthetic 75w-90 gear lube and GM limited slip additive. The service manual (2004) recommends a synthetic 75w-90 axle lubricant and the additive. Mobil 1, Redline and Amsoil are popular choices and probably less expensive then Mr. Goodwrench's product.

Could you please let us know how difficult a DIY this repair is? Most of us will probably end up doing this once the cars come off warranty. And I haven't seen any post on just whats involved. Are there any pullers that are required etc. Or is it just a lot of parts to get out of the way before you can replace the seal. That is if you don't mind!! 
Keep us posted if you don't mind.
