ATTENTION all current AMSOIL users
Another referral vote for Heath. I have been a customer with him for a good while and I must say that he is there when you need him, no doubt! Noone will go wrong with either AMSOIL, OR buying from Heath.

Hey, sorry it took so long to repsond...bad day
The severe gear 75/90 is the OEM recommended fluid for both front and back. Many who tow a lot like to go with the 75/110 in the rear. Just a little added cushion but not required. No flush is needed but if one wanted to, the best thing is to drain and refill with some inexpensive gear lube and run a few miles then dump again. Not really necessary unless you find it to be really dirty when you drain it.
It's 4qt in the rear and a full 2 in front, many get 7 qt to be safe for the dmax. I'll pm you some pricing.
