I have Yukon 4.56's in my truck. Been in there 3 years & many miles. Did the 2007 Power Tour right after I installed my setup. Did 2800 miles in 8 days. Never a peep. I'm critical myself when it comes to noises, too. My GTO has plenty

Not sure what you mean by noisy. Maybe the rear diff isn't set up correctly (tolerences). Could be a bad carrier bearing or even a pinion bearing. Even an axle bearing could be noisy.

Maybe give us a little more info IE when they are noisy - off/on the throttle, cold/hot, etc.
