Noise caused by new gears?

Yes, I did search but did not find what I was looking for..

Last fall I had 4.56's installed by a reputable shop locally here in town. In the last few months I've noticed a small whine from somewhere around 35-55mph. It is very noticable when it goes down into OD. The noise is now more than noticable and I'm pretty sure that it is probably my rear end not set right.

My question is this, I only hear the noise when I press on the gas. When I let off the whine imediatly goes away. If the ring and pinion are not set right will it whine all the time even when coasting? I'm only hearing this noise when I have my foot on the throttle. Somtimes it almost sounds like it is comming from the transmission. Thanks in advance for your guys' input!
