I did not experience anything like what was shown in those Edmunds videos. Both of my drive unit replacements were due to the "droning" noise above 70 MPH, which seemed to peak at around 20 kW of power. Unfortunately, constant 20 kW input is almost exactly what is required to maintain freeway speed. The fix has something to do with the updated motor mounts.
My original drive unit was quiet, but it developed an oil leak at 8000mi and was replaced - my new unit has this exact noise, but the service center has declined to replace it.
