My ARB locker manual calls out for SAE 90wt both front and rear. Its good from 10deg F to 212deg F. If it gets colder I think it says 80w-140 or something similar.

After the install I ran conventional 75w-90. I switched to 85W-140 because of the extreme heat and lack of cold winter temps out here. Never had issues with either.

I dont run ARB's but I started running full synthetic 80-140w IIRC. after my gear and locker install.

I ran 75-90 Mobil 1 Synthetic. With the amt of $ of the arb U want to run the best, check the diff often after deep water crossing and such too. I checked mine right after the really deep 1st water crossing on Fordyce because that crossing swallows up 37's. Very deep water there.
