Hey guys, how loose are the factory tow mirrors suppose to be? Not the arm, simply the mirror part. On my driver's side, the mirror was really tight and stable when I first got the truck. After driving for about 3 weeks, the mirror itself has become looser (and pivoting seemingly excessively free about its axis), to point of moving and in need of re-adjustment every time the door is slammed closed. Anyone else have this problem? By the way, the mirror does not vibrate when driving, and works fine. Would appreciate any input. Thanks
