This rattle was ice for me but another rattle developed and I believe it is the wheel well plastics. The push pins needed to be tightend , specifically the larger ones
for reference

In the 2018 f150 forscan disabled the system completely, rendering the button in the truck useless. Not sure how many codes you had to change but I had a buddy do it.
Installed some 225 65 17 bfg ko2s today! They look and perform so much better than the continentals in the snow. Unfortunately the dealer scratched all 4 rims on the tire machine but they are replacing all 4 at no cost.
Hey guys,
I have a weird rattle coming from the b pillar at above 40mph, can't pinpoint what it is. Nothing is loose or flopping in the wind. It's almost like the road vibration at the speed causes it. Any one have a similiar issue?
