does the noise change with engine speed or car speed?

My AU had some insane diff whine, that was caused by a stuffed pinion bearing. It could be anything driveline at this stage.

its like its cringing as the revs drop back down haha. just whenever the revs are dropping with clutch out and in gear it does it. with clutch in or in neutral its fine.

My AU did the EXACT same thing, it had 6mm of play in the pinion. Sounds like it's the diff from what you have described.
