IUpdate Dec 22 , I was at dealer in 2021, couldn't create the noise, just recently , I used my experience working at the Oshawa Trk Plt (retired) ,in my shop, flat surface, rolled down front window , lifted door through window opening in door, door can be moved up and down on hinges and door latch plate with door fully closed and latched. I will be contacting GM and Skeld before returning to my dealership.
