At 10k, I am going to replace the oil in my front and rear differentials on my new Tundra. What is the absolute consensus best to use? I am switching to sythetic engine oil at 5 k miles here in a few weeks and I want to do whatever's best for the diff's since I plan to drive this thing forever. Also, how about the xfer case? Is it, or parts of it, getting any use in normal 2wd driving? If so, what's the best fluid to use in it; if not, i'll wait a while.
Thanks!

Not sure on Tcase fluid type but in axle since you have gone SYN in engine, try 75w90 SYN and not 75w140 SYN. YOu want to keep it a little lighter for max MPG and 75w90 or 80w90 is spec'd for it anyway.

Your choice of any top quality synthetic 75W-90 differential gear oil in all three gear cases. You will like Mobil 1, Red Line, Amsoil, Royal Purple.
