Differential maintenance.
Although I am not a mechanic, I do have background in maintenance.
A few thoughts:
If the diff needed flushing, if there were a known maintenance requirement, it should be a scheduled service item.
If the diff has not been maintained, flushing is not a bad idea, but does it indicate any consequence of the lack of scheduled fluid replacement? Might be a gamble, and a cheap one too.
If flushing was done, it is possible the fluid could be filtered, or more sophisticated analysis, to give some indication of wear and damage.
Flushing it out suggests that that a simple fluid change isn't sufficient, yet the scheduled service doesn't require flushing, just fluid replacement.
I would be the kind of dreaded customer to ask these questions.
Google FMECA. If I know about FMECA, shouldn't Honda?
