Absent except when between cruising & light acceleration, with a little higher whine accelerating?

4th is direct drive, so less competing gearbox sound lets you hear the rearend more.
R&P will be whiny when not setup right & depending on which way it's out, can make more or less sound the heavier they are loaded.

Yes that's exactly that.

The car was undrivable above 80. Id say your problem comes from the gearbox rather then the rear axle...

I will try to find a gearbox of my friend and change it to check if the noise is still there.
