04 F-150 SCrew Lariat Hood Vibration


Anyone have it?

With a little speed or headwind my hood vibrates and jumps in the rear where you can hear it and see it through the windows like it is going to rip off and go flying.

Took it in once already, dealer said there was a TSB and that they had to put, of all things, a filler in part of the hood? Anyone heard of this?

Anyone have the TSB?

Well, it didnt work, seemed to get better, at least for a time, and now its back, but maybe not as bad as when it was new. Only 5 K on my truck.

Thanks,

Dave

 

Do you have a bud deflector by any chance? They do cause what you are describing.

 

Yes, thanks, however, it did this before the bug shield, hoped that would help...

What type of bug shield do you have and was there something you were able to do about it?

Thanks,

Dave

 

I had a Ford low profile and the problem went away as soon as I took it off. The hood is aluminum thats why it flexes and shakes so much at the mounting points. Just another one of Fords better ideas.

 

Hey Dave, mine DID the same thing. I fixed it myself(dealer simply said it was due to the bugshield and tried nothing) I got the TSB fix from "another" truck forum. Mine "flapped" excessively at high speeds. With the fix I've gone 90mph w/ absolutly NO flutter. Hope this works for you also. (my shield is AVS brand)

TSB 04-18-8 HOOD FLUTTER AT HIGHWAY SPEEDS

ISSUE:

Some 2004 F-150 vehilcle may exibit hood movement at the back of the hood due to high air turbulence, while driving at highway speeds. This condition may be amplified by the installation of an accessory bugshield and may be more pronounced when passing an on-coming vehicle on a two lane road.

ACTION:

Refer to the following Service Procedure.

SERVICE PROCEDURE:

Confirm that the hood is flush with the front fenders at each front corner. I 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. It 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 hose147cm long& 11mm diameter( 58" long & 3/16" diameter). Lube the hose with a soap-based solution and install the hose inside the hood seal bulb.

 

Thanks to all! Especially blue blooded...

Still would be interested in hearing other stories about this..

Drivers mirror or panel next to it is also making much noise!

 

I have the same problem with my 05 Super Crew. I will be taking this TSB to my dealer. Thanks.

 

Yeah, thanks to everyone.. And thanks to this board and its operators! Its been a life saver, and if I could figure out how to do it, I would donate. Wouldnt be much, but I am sure every little bit counts!
