Redline 75w90 should be good. Did you fill the diff until it started to leak out of the fill hole? If it still makes noise then you might have to get an addional friction modifier to add to your diff. I've seen a little bottle of friction modifier at Napa before. Its a small white bottle with a red label saying limited slip differential supplement on it.
75w90ns is the one you don't want to use if you have a lsd.

Your lsd is ******* fine. add a friction modifier. And tranny oil and diff oil are the same thing. Some formulations are for one or the other, but they are both gear oil. It's all preference.
