It seems to be a common problem no matter the industry.........in my 36 years of flooring, carpet for a commodity example since it is a relative no-brainer to install PROPERLY just as setting up Ford or Chevy rear end gears is, the manufacturer more often than not pointed the blame at the blue collar worker first (we all know they don't possess fancy college degrees.....) when more often than not it was a simple manufacturing tolerance defect due to numerous cost saving measures (opportunities) implemented in their processes.
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?
