Nice work! Reps to you.

I went looking for this problem one day. Took the cowling off and cleaned it up in there. Put it back on and replaced the center gasket with 3M double sided molding tape. That made it a little better.

Anyone getting a slight tapping noise from that area?

 

i'm now having this problem with mine.
was wondering if KingJl is still satisfied with is fix?
just because i'm hearing stories about being windshield trim.

 

Still satified!!! Have not heard the noise since I removed and reset the aux seal. Before that it had gotten so bad that any time we were in the truck and got to 55 mph it was occuring. I also heard the windshield seal & winshield trim stories/theories. They didn't make sense with my understanding the physics of sound. When I found this (with the hole covered by a membrane under the aux seal) it finally made sense. Regardless, it fixed my problem... no conjecture... just fact!

 

Good to hear! so, I will look at this today and at same time i was thinking to maybe addiing a little bit of clear sillicone to prevent the loosening latter. Unless you have any objection to it. Did contact the dealer earlier today and under waranty they are willing to have the windshield re-seal just in case it would be that and good customer service.
The only problem is, having all of those things at the same time, i'll never wich one it was causing it.

 

It could be either side. Mine was the passenger side. If you're going to try any sealer (I didn't. I just removed and re-installed the aux seal), I would think you would only want to do the leading edge (to divert air around and not let it get inder the aux seal). Good luck. Maybe you can end up as happy as I am!!!

 

Will post result as soon as fix and encounter same situation that did cause the wistling.
Thank you for your help! Now lets wait and see (or hope)!!!!!

 

Here is my update, like a mention before did all necessary mod to aux. wheather strip and also Cowl gril seam, had my windshield re-seal this morning and i was able to be present when they did it. Actually, they remove the windshield to re-install it in the process they did find a 6" to 8" gap on the top part of the windshield delaminated from the urethane, cause by lack of insufficient urethane on assembly line when they built the truck. So, by re-installing it able them to be generous on the urethane. Conclusion, in my case the windshield urethane seal was faulty, just a re-install and everything is perfect and seal up. Just like brand new. No more "anoying noise".
I strongly recommend to every body that have that noise to try first the aux. wheather strip and cowl seam then ie required have your windshield remove and re-install properly. That should fix it for good.

 

So King Jl, because i did everything at the same time i can't 100% garanty that it was cause by the windshield since i also did what you did, but i still had something wrong with that windshield integrity and at least now that is fix. So, thanks to the forum for all the helpful advise and making this a success fix!!!!!
Love this site, really good info!

 

Just got my truck back frm the dealer for the same issue. They found the problem, but the foreman didn't hear. I rode with the foreman and he heard it. He thought it was the seal on the windshield. Had all the seals redone and now no noise. Like you, only happened on the freeway and at higher speeds. Only 200 bucks. Mine is also 08 250.

 

Too bad you had to pay for it. But at least it's fix!!!! Good to hear!
Mine was covered by 3year/60,000km waranty (even with 62,000), Dealer claim a water leak to Ford to have covered. (and claim a lower km)
Even if i would have need to pay, i would have done it in a heart beat.

 

Have over 100k on mine. No warranty. Well worth the money. Wish I woulds seen this thread first though. Woulds had my truck back a day sooner.

 

Wow...where has this thread been all my life. Mine has gotten so bad it gives me a headache. It used to be just now and then, now it's all the time. It did it today going 40mph down the access road. I will be all over this fix tomorrow. If it doesn't do it, it's going to a windshield shop. it is bad.

 

Mine does it too. I installed Weathertech vent shades shortly after I bought the truck and heard the noise shortly after that. I just assumed it was the shades causing it. Here in Ky. we don't have high winds very often so I guess I will just live with it.

 

I bought a 2010 F250 Super Duty, 4WD, Crew Cab, Diesel and started getting the mysterious wind noise driving on the Interstate. It only happened under certain (crosswind) conditions or when passing semi-trucks. The first time I heard it I thought someone was honking at me.

Once when it happened I had a small videocam with me so I recorded the 'event' and put it onto a DVD to show the service tech at the dealership. The mechanic took the truck out and surprisingly he was able to replicate the noise. I read (on the forum) all the various theories as to what was causing the noise which I passed onto the mechanic for what it was worth.

The mechanic focused on the windshield seal which I could tell by the remnants of tape around the glass. The dealership sent a glass company to my house the next day to replace the windshield (with another OEM windshield). After breaking the seal and taking out the windshield the glass installers told me they thought it was sealed fine at the factory. They were skeptical that was the source of the wind noise.

Despite the glass installers saying they thought the factory windshield was sealed fine, replacing the windshield seemed to fix the wind noise problem for me. I've driven on the Interstate numerous times since and I haven't experienced the wind noise again. I hope this helps someone.

 

Heh...well, this is a rather old post now (over a year ago). And as you can see, I fixed mine by trading it in on a new truck! Yeah, that fixed it good.

Seriously, I hope everyone else got theirs fixed. That was really an annoying issue.
