Limited V6 4WD, Differential fluid help

[teneck31]

Hello,

I have a 2004 4runner and need help with suggestions on fluid for
1)rear diff
2)transfer case
3)front diff

Do I need limited slip additive in either one? I purchased the fluid already and it says it is good for both limited slip and conventional. Please help with recommendations. Who is putting limited slip oil or additive in their rears/front/transfer case?

I think Toyota specs 75w90 for front and rear pumpkins and 80w90 for the transfer. I've been running the cheapest Walmart coastal 80w90 in all three and haven't had a problem 252k going strong. I change every 50k. I'd recommend getting some type of fluid pump will make life 10 times easier.

It's not necessary but okay if it has it so the stuff you have should be fine if it's either 75-90 or 80-90.

Yes, using LS version oil is fine. The specs above are correct. Through I used 75w90 in all 3, Mobil 1.
