Dude - I chased that front of door rattle for weeks and removed that switch trim countless times. As someone else on here recently posted, it's actually under the triangle shaped trim piece at the bottom front of the window. Pry that bitch off and put some hockey tape around where the clips go through. Damn deceptive rattle, but easy fix.22 gen 3 purchased in late April of this year. A few things have happen with her for sure:
-In Sport mode, pulling hard at around 60 truck would not shift and over revved pretty bad (lost all manhood)
-Red-light race with a Corvette, floored it. Good acceleration then rpm drop like it ran out of fuel then back to full ( Found man hood for a moment)
-Tailgate Pop really loud for a few days then went away ( Something broke inside me)
-Loud Gunshot sound ( literally the Wife and I ducked, Atlanta) never thought about it coming from the radio ( was not listening to gangster rap)
-Stereo used to reboot a lot at first ( 4 or five times) but has not in the past 3 months. ( not enough coffee)
-Rattle in the front of the door somewhere, I touch it, it stops. (OCD RAGE in rush hour )
-no two finger wave salute from gen 2 owners ( screw that dude and his gen 3 that I don't recognize)
-Paid 10k over and still feel stupid ( but she is a pretty lady)
Currently at around 10k miles and everything else is normal. Starts perfect every time, pulled a few trailers and a camper (30 footer) like it wasn't even there. Put a negative offset wheel on and now she's like an Indy car on the on ramp race to the apex! love the interior's spaceship feel over my Gen 1 and Gen 2, but I still prefer the look from the front of the Gen 2 the best. Have fun fellow Beast mode ford enthusiast.
