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.
