I'm planning to change my front and rear diff. this week. im also planning to do the cocktail fluid for the front. but i can't find the type of fluid for it at any auto store. i live in chicago, if anyone can let me know where i can find the fluid it will be great. Just to make sure that the fluid im lookin for is 2qt. vavoline 80w90, 1qt of shock proof lightweight, and .8qt of gm sychormesh. if im wrong, please let me know the right fluid... thanx

 

Hey whitewrx23,

How did your differential fluid change go this week? I'm looking to change mine too but I was wanted to get a few pointers first. Any advice you can give would be great. Could you take a look at my post and let me know if you have the answers to any of the questions I've got?

Thanks.
