Diff whine

Curious to know how many M2/M3/M4 owners have a whine on their diffs.

Hi

Yes I was going to try that before any drastic measures. The diff seems to be doing its stuff and there are no horrible noises.

Mine whines most of the time you can hear it cruising on quiet tarmac. Saying that it’s no worse in 8 k miles.
