Gears & Axles - Moser Rearend whine

I just got my rearend installed and did the initial breaking of 2-3 minutes in forward and reverse. You can hear a whine with the door opend at higher speeds. I hear that things can be adjusted to fix this problem before it gets permanent. What exactly do I need to get done? I'm going for a full alignment so I can get the gear pinion angle adjusted if need be. What exactly should I do?

I dont think there is much you can do. If you go diectly to mosers site, it says the gears will make noise.
Mine have been making noise since day one. The moser has been in my car for about 1 1/2 years not. Supposedly its the "nickel" in the moser gears and also how the backlash is set up

I never setup the 'backlash' - can someone do this for me to reduce noise?
