How difficult was it for you to unscrew the yoyo? And also how difficult was it for you to remove the bearing, do you see any marks of ano stripping off the bearing posts?
My brief guess would just be that the fit of the bearing post was extremely tight to begin with and just sanding down the bearing post a tiny bit will solve you issue if that’s the case. There was a thread about bearing posts being too tight a few months ago.
