Hood shimmy with bug deflector
Howdy y'all,
Well, I know a lot of people here see their hoods shimmy with a bug deflector installed, specifically the Stampede. I was driving home this morning and noticed the dew on the hood was running towards the front of the truck instead of the back and sides.
So, this leads me to believe the bug deflector is altering the wind current so it creates a cowl when it hits the windshield. (the same effect as a closed in tailgate, where a pocket of air rotates between the front and rear edges of the hood.
So, when this air loops around, it lifts the rear of the hood.
Now my only question is... anyone know how to keep the hood from lifting???

I was looking and I was thinking if I put some insulation similar to door insulation between the hood and the black plastic that it could prevent wind from scooping it up. Anyone have any suggestions on what to use there?

It's actually designed to cowl, because that's where cabin air comes in - the black plastic piece that buts up to the windshield. I know I've seen vehicles with insulation between the back of the hood and wherever they but up, so I'm wondering if Ford design team just dropped the ball here.
