E30 325 IX rear end noise

Hello everyone! I bought a German 1987 E30 325 IX in February 2019. It still has 4WD and I just adore it... to an extent that I got used to that damn whine noise coming from the rear end. So I changed the diff but the dumb mechanic fit a 4.10 rear diff (the front diff is a 3.64).
So the whine got much worse when accelerating and decelerating, therefore my friend swapped the diff with another diff (he changed the pinions and gears and reverted everything back to 3.64 and told me that the LSD mechanism was in good shape). However, the whine is coming back gradually despite changing the gears of the rear diff, putting new and best quality diff fluid, and fitting a new diff mount. Am I missing something? What should I do? Is that a bearings issue? Someone help me out please because the noise is just frustrating!
