Recently I discovered a ferrule that would move a tiny bit. I can pull/push/twist it about 1/8th of an inch, and then it would be stuck again. If I apply force in the opposite direction, it would loosen and move the same amount and be stuck again. How concerned should I be? Do I need to find a way to remove it (any ideas how?) so I can reglue it ASAP? Or should I just check on it frequently and deal with it when (if) I can pull it out? Thanks.
