Hey
@volcomrr, I at one point had most of the interior parts and panels removed from my brand new MegaCab because of a rattle. This included the whole storage bin and subwoofer behind the rear seats, it was coming from much deeper than there. There were no less than ten thigs I found that had the potential of creating a rattle and secured all of those items with no result.
The hunt to find where it was coming from moved to underneath the truck where I found another dozen things that may cause a rattle, securing them only to still exist. So I resorted to filming the undercarrige trying to pinpoint the noise and it is coming from the very aft cab mounts. I havent made it to the dealer to have it checked out yet but have discussed it with them and they claim to have no knowledge of an issue but there are plenty of people posting about it. If they ever have the parts available to perform all of the recalls I will have them address the rattle while it is in for those. I have attached the link to the video below again.
