The superglue or locktite will work but if you ever have to adjust your mirror, you will break the glue and have to do it again...Do it right.....take it off....there is a piece of spring steel that keeps pressure against the ball socket......tighten the screw (if loose)....or if ball is worn a little put a piece of napkin under the spring steel and tighten screw down.....works like a charm....I have done it many times
