New moser 9" whine

New moser 9" whine
So i just finished installing my moser 9 " wavetrac and it now probablly has about 10 miles on it. From the beginning it has a terrible wind up whine from about 25mph up. once i get on the freeway its pretty over whelming. I bought this rear end because i was told that moser had fixed the gear whine problems of the past and that is rare to get one with problems these days. My question is does the noise go away as you break in the rear?

Installed the rear yesterday and drove it for 10 miles, very minimal gear wine on mine. I did notice as the wheels were spinning sitting on jack stands that they had a wobble to them, anyone know if that's normal, the wheels are custom made since the rear is narrowed 2 inches each side

Tom, what you thought was a problem with your Wavetrac is not a problem at all. Those are alignment pin holes for when the unit is assembled. Once assembled they are removed. Moser Engineering does not manufacture or assemble the WAVETRAC units, they manufactured and assembled by Autotech. I had Moser send you free a new ring and pinion and bearings several years after I sold you your rear, it would of been nice if you didn't go on a bashing spree. Bob

update
well i pulled the unit and had a pattern run and thanks to some help from Bob sent it back to moser for them to reset my gears. When i got it bakc i checked the pattern again before install and it was set exactly the same(centered on coast and heal on drive). I find that pattern odd because from what i read if anything they would set it up on the toe side for race purposes. Either way i had a local shop re-shim it and they got it centered on both sides. Installed it and no gear whine what so ever. Unfortunately i now have a vibration on drive and a harsh ride where i feel all the bumps, i have plenty of clearance on the torque arm so ive concluded it is probably the pinion angle, i believe i have it set around -2. Ill try messing with it later on and see if it goes away

I have a lot of whine coming from my rear end.
However, I know for a fact that my torque arm rides against the driveshaft tunnel and the arm-to-bracket bolts protrude far enough that they touch the body. On top of that, the bracket-to-diff mounting sleeves impact the body under full compression.
With all those contact points, that would be the cause for all my whine and squeaks right? I'm hoping that I don't actually have backlash issues... I don't have paperwork for this axle.
Also, I'm curious if I should try a different fluid that might quiet down the noise being created in the diff. Eliminating the telegraphing o the nvh is not possible in my current setup. I'm open to suggestions for fluids though

The US Strange gear is a good strong gear for sure and I am sure it will hold to anything I will throw at it. But, I am going with a Yukon 3.89 this time. If it makes noise I am running it. My power level has went up since the 402 install and my exhaust is loud enough that I cant hear the 10 bolt make noise anymore, which it does. Yukon is suppose to be one of the quietest gears made. That's why they cost more, and that's why Moser probably didn't put one in your rear, you probably have a Motive, which is still a good strong gear, but they tend to make some noise.
More than likely your rear is fine, nothing wrong with it, its just noisey.
