I drive a 2014 3500 crew cab dually with a 6.7 diesel. I'm picking up a loud rattle that sounds like it's coming from the outside on the passenger side towards the front starting at exactly 65 mph and it quits at 67 mph. It has no effect on the performance of the truck whatsoever. I have been through the truck from front to rear bumper and tightened anything that looked even remotely loose or out of position. I been trying to find this gremlin for almost a year without any luck - any ideas?
