If the mirror is wobbling around at the windshield mount u can take it down a take the ball socket off, give it a little tap with a ball peen hammer ad since it back together. But if it’s worn out at the mirror u may have to get creative. Kim.
I finally got around to fixing the wobbling rear view mirror I took it apart and hit the ball part at the top with a hammer 6 or 7 times put it back together and it’s all fix thanks for the advice
