This is so called 'noisy diff'. My dealer changed the diff oil to (SAE 75W-140, SAF-SJ, +FM), trying to make noise disappear.
I have followed the instruction to make 20 times of left and right in a circle after the fluid changed, noise seems to be getting lesser but still around.
Now, even I get used to the noise but not from friends of mine. My simple answer to them is “hmmm….. this is ‘M’”
