I have tried searching but still have a question.
I have a 2004 LX470 and was wondering what fluid do I need for the Center diff and the transfer case?

 

[Rhetoric]

The center diff and transfer case are one in the same.

I like Delvac 75w90 for the TC.

If you're changing the fluid, I recommend adding AT-205. Its been proven to extend the life of the rubber seals, and changing the output shaft seals on the transfer case pretty much sucks.

That all depends on how much you want to over think it lol. I've been just running the 75w90 all around for 100k miles without any issues. If you're in a hotter climate going to that thicker 80-90w as noted in the manual below wouldn't hurt. Just make sure everything is at the proper level and clean and it'll be good to go


If you decide to go for the front diff go easy on the fill plug and make sure it breaks loose first. A cheapy little fluid pump will help to fill the system after you drain it

I kept it simple and used Amsoil 75W-90 Severe Gear oil for everything when changing mine in my '02 LX470. Almost two years/10K miles and no issues.
