I have a 2018 F-150 XLT SCREW 3.5EB with 10k miles. I've started to hear a loud rattle that seems to be coming from behind the gauge cluster towards the windshield.

I've tried adding felt tape around the trim near the gauge cluster as well as adding felt/weather stripping around the cowl on the outside of the truck. Didn't help. Has anyone else experienced this? Any idea what it could be? I don't really want to take it in to the dealer and have them tear apart the dash as that would probably lead to more rattles!
