I'm quite meticulous about my car and like to keep everything up to date on fluid changes etc. My rear end has richmond 4.10's in it that whine a bit, I'm not worried about reducing the whine too much, just want to do what's best for the car.
I bought two quarts of royal purple 75w-90 and I'm not sure on which cover gasket to purchase, and if I should use the additive or not, and if so should I use GM or Ford?
Thanks!

With rp u do not require the lsd addictive. but I think your rear end require running regular non syn 80w90 with lsd addictive. I alway use felpro gasket for 10 bolt, with tiny of black rtv on each side of gasket,

So... I should return the Royal Purple, and pick up some non synthetic blend 80w90 and a bottle of additive from GM, along with a felpro gasket and add some black rtv to it?
