If wheels are run loose, both stud located wheels and hub piloted wheels can
be damaged. Look for wallowed out or elongated ball seats on stud located
wheels. On hub piloted wheels look for elongated stud holes. Over torquing
can lead to damaged ball seats on stud located wheels and can damage
the disc surface of hub piloted wheels. Remove damaged wheels from service.
