im going to replace the fluids in both diffs and the xfer case when my front prop shaft arrives next monday... i found the viscocity (correct me if im wrong 75/90) and the approximate amounts required (4.1-4.8 pints xfer and 3.4-3.6 per diff).
now only thing i noticed is that it says the xfer case needs atleast api gl5. the amsoil meets this requirement, so my only question remaining really is...
do i need the friction modifier additive like my trans ams rear diff did? (think it was called gm limited slip additive) but i didnt see any mention in rave about slip additive... just wanted to be sure before going out to the diesel truck shop to grab the lube its abit of a hike, i dont want to have to make 2 trips if i dont have too.

alright thanks for the info, i havent done any reading up on the type of axle, trans and 4x4 system in these trucks yet but im paranoid so anytime i get a new vehicle, everything gets changed asap.
ps. recommend changing the cover gaskets (101k miles) on these or are they pretty good for now assuming no leak thru detected when i get under there.

You can use any brand of diff and T/C gear oil you like.
But after using Mobil 1, Valvoline, and Royal Purple. I really like the 75w/140 Royal Purple. It seems to really make the gears smooth and quiet the Transfer Case. It will set you back about $100 for 6/7 quarts @ $15 per quart. But you can always use Wal-mart Tech(Something) Fully Syn brand for about $10 a quart if you want to save some cash. Change it once a year regardless if you do many water crossings.

Lol, I know you just "got" the truck and have not been under it yet, so yes, go ahead and change the gaskets to the diff covers.![Big Grin](https://landroverforums.com/forum/images/smilies/lxvR5hR.png)
Buy 2 of these before you change your diff fluid though, and use them on the fill plugs instead of the plastic ones.

I think Spike meant you wanted this Brass D1 radiator plug. This replaces the plastic fill plug on the DII diff. Rova Farm is a great place to order from. I have bought a few things from them.
