I am starting to belive these diffs are just loud. Too many people have had noise then replaced it only to get some noise back later.

The rear ends all have the same part number. The rear end is one complete unit compromised of many parts. No matter what part you buy for the car, the part number will always be the same. If the part number is different, then the part is different.
You are incorrect in your assumption it is the nature for these rear ends to be loud. Mine is as quiet as a church mouse. Every car or truck I have ever owned in my life was never loud. The car manufacturer does not build a car to be noisy. If there are noises coming from the rear it is not normal. Dana built a bunch of bad rears, some guys who have had their rears replaced got bad rears again. Some took 2 or 3 rears installed before they got a rear that was quiet.
I have ridden in many performance cars and have not experienced loudness coming from the engine, transmission or rear end. The easiest thing one can do is dismiss it as normal and forget about it.
My replaced rear got noisy a while after it was installed. That problem turned out to be a break down of gear oil viscosity. Had I dismissed it as a "normal" loud noise eventually heat would have gotten to the gearing and turned a simple fix into a major deal.
GM opted to replace rears, if the noise was normal, they would not have spent the money to fix a potential "non problem."
