Flapping noise at high speed

[smoreho2]

First off, I'm guessing that you do not have a soft tonneau cover?
I believe the post below shows the area between the outer fender and the inner fender where the insulation is. I hope this helps.
Good luck.

Thank you!

Don’t suppose you have a pic that would I’d where yours was in the door/fender do you? I want to make sure I am looking at the right thing. Still have the noise but what I checked was wedged fairly tight. Thanks for this info. Driving me crazy

These pics show the foam block, the empty cavity between the driver's door and the A pillar and the passenger side with the foam block in place

The foam block that came loose and was laying on top of the inner fender beside the battery

This is the driver's door side where the foam block sits

This is the passenger side with the foam block still in place
