Hey everyone I recently picked up this '99 CRV 5MT. I drained and filled the rear diff with The Honda II fluid but it was making the same noise before just as it still does. We had some snow a month back so I decided to make a video, where I badger about the noise lol. I was basically slipping the clutch to make the car spin and right when the 4wd seems to kick in or the front wheels spin, that noise happens. It is super loud and I can replicate it a tiny bit if I slip the clutch in 1st or second when it's raining. Any help to what this is will be appreciated.
