Question for Differential Experts

I have a 12 bolt posi I bought from a small shop. The housing is OEM but the posi unit is a new Yukon it's got new 3.08 gears, new bearings, new steel axles etc. The rear end whines constantly under light load and stops when you back off or let off the accelerator. The guy that I bought it from said it's the gears and there is nothing that can be done. I don't buy his response, but I can't make him fix it. I want to know what I need to do the get this rear end quiet like it's supposed to be. Thanks
