The reason for the excessive noise needs to determined and documented and thrown back in the manufacturers court. IMO - It creates an opportunity for a manufacturer stand above the rest. A set of GM 12 bolt gears is around $325 + labor to have them set up in my case........if I had a guarantee that a $525 set of gears would be OEM quiet it would be a relatively easy decision.
Why could GM make them quiet back in the 60's and in today's hi-tech world the manufacturer can't match 60's era production quality?
Are the noise issues more common in Ford vs GM housing designs or low vs tall gear ratios?
Inferior:
Materials quality?
Milling specs?
Milling equipment?
Finishing process?
Carriers?
Housings?
Mechanical noise?
Harmonic noise?
What causes the issue?

If I had to guess, horsepower and the material used to hold up to the abuse. We are using OLD technology that needs to hold up to nearly twice the power it did 30-40 years ago.
That's what I found building my car. Every step I took to increase performance resulted in more noise, more maintenance, and less reliability.
New OEM stuff has been engineered from day one to be quiet and live at the specified output.
I still think a rear should be reasonably quiet. It may come down to finicky specs due to more aggressive material. I don't know, someone will figure it out with their pocket. Glad it's not mine. ha
