Hood "tremor" at speed

Area51BS - THE FOAM SYRAY SOUNDS LIKE A GOOD IDEA!

Same issue on my new BS. Had it on my Chevy Colorado. GM injected spray foam to correct it.

Youre joking. The was GM’s fix?
that’s sounds like something I would do!

This was a service bulletin for the F-150 posted in another forum. It fixed the issue for the truck...maybe it works for the sport.

"SERVICE PROCEDURE

Confirm that the hood is flush with the front fenders at each front corner. If the hood is under-flush, adjust the hood stops to raise the hood flush with the tops of the front fenders.
Check the amount of drag at the rear hood to cowl seal with a piece of paper. Place a piece of paper between the seal and hood, close the hood and then slowly pull the paper out.
If there is sufficient drag, indicating good seal to hood contact, return the vehicle to the customer.
If there is little to no drag, obtain locally a piece of fuel hose 147 cm long & 11 mm diameter (58" long & 3/16" diameter). Lube the hose with a soap-based solution and install the hose inside the hood seal bulb."

Dumb question but where do you spray it?

Also to those saying drive slower than 75 or 80...I believe both Texas and Montana have speed limits of 80-85...which generally means 90 here in TX

add OK, WY, UT, SD to that and it’s very limited stretches of road.
I did enjoy that toll road in Austin when I lived down there.

anyway I’m not sure Ford intended this little box on wheels to be doing that! which bring up a question… is the Badlands governed? Or any of the sports?

Where did they inject the spray foam under the whole hood or part?

I drive 85-90 all the time and my hood is solid (NO DEFLECTOR)

Thank you , I have had this idea for a long time . I just needed someone to confirm this.. It makes sense because you are filling the voids where the air is being trapped. This will give it some needed stability as well..... thank for this info

Before spraying any type of foam, I'd take the service manager for a ride to demonstrate the issue, then have them correct it.

Does anyone else see a hood lift and tremble once they are at highway speeds? I recently did a long run across Montana and after a few hours of 80 mph this movement became pretty annoying! I took it to the dealer and was told this is not an issue they have seen and so no fix for it.

Remove the wind deflector

i also drive 80-85 mph all day long with no hood vibrating. Take off the stupid deflector

 

[Colonel Angus]

Hood struts reduced the vibration. It didn't completely get rid of it.

That and does your hood have the two side pieces of rubber weatherstripping? It's one of the many missing parts that Ford deems unimportant. I added them on mine but I never do 80 so I'm not sure if it might help with the issue. Worth a try though.

It is not air being trapped. There is no bond between skin and under hood skin bracing

I have done some research and this seems to be a possible fix.
Ford is well aware of this problem and they dont have a fix

I’ve had two bronco sports with deflectors and two without. One with and one without was a 1.5L and one with and one without was a 2.0L. They all vibrated, some closer to 70+ and some closer to 85+.

No offense, but either yours is special or your not observant is my non-scientific conclusion.
