Honestly no idea what it is...gathering evidence before the jury makes the call here and get dirty. I got under there briefly and gave it all a good shaking...motors are def a little clunky sounding sitting still in their mount or position so again just an educated guess or theory to work on...
@ Pelican - any luck with the Rattle from the Linkage or Motors? Chasing these annoying sounds as well and 90% sure it is what you are experiencing as it is mostly at above 45 mph... Thanks for your persistence and posts.
