Irritating humming noise.

[foreverstorm]

If the vibration was an out of true driveshaft, and they put in a new differential, that tight fitting would definitely set up a new harmonic that in this case seems to have been noisier; no surprise, actually. How long did you drive with the new differential? Because the longer an out of true driveshaft interfaced with a replacement differential, the more unevenly worn it would become. So, if that has occurred (some diff wear), the brand new driveshaft is interfacing with a worn differential; this could go on indefinitely unless "they" replace both at the same time.

Less than 500km between the replacement diff and the new driveshaft, though the sound and vibration was very significant. Would that be enough to ruin the new diff?

I shouldn't think so, unless those miles were mostly hard miles, like a bunch of launches and other high RPM stuff.

FWIW - I have a slight humming/buzzing sound as well. It's like a subwoofer is on a very low frequency. I chalked it up as the exhaust (stock) and the Michelin tires on the car. Does the note change when you crack a window? It doesn't bother me, but I did go to breakfast one morning slightly hung over and it wasn't all that pleasant lol

Same problem here but with a 2021 seltos SXT
ITS VERY ANNOYING.
