I have a 2004 F150 super cab and since owning it have had very few problems and never any major mechanical issues with it. It's paid off and still running strong. The only thing I can't figure out about it, even after 5 years, is why when I roll the back windows down at highway speed I get an eardrum pounding "whump, whump" sound that seems to pulsate through the cab. The pressure is hard enough to hurt your ears and distort your vision, and it literally sounds like a chinook helicopter is landing on top of the thing. The only way to alleviate it is to rolll down all of the windows, which I don't like to do. I assume it's something to do with the aerodynamics of the vehicle, but I'm just curious if anyone else has ever experienced this or found a way to reduce or elliminate it?

thanks,

JR

 

Do you have a sliding rear window? If so, open it about an inch, problem solved.

 

Open the front windows, problem solved

 

dont roll the back windows down... problem solved.

hehe, theres one is every crowd.

 

It is the imbalance of air trying to enter and leave the cab. If given a small slit or avenue for the air to travel front to back it will not do that.

the ford freestyle does this extremely bad. It actually hurts everything on your body. I thought the windows were going to shatter. I have an 06 scab but don't have a problem with the "helicopter effect".

 

Same thing happens in my fiance's car (Pontiac Vibe) with the sunroof. If you open the sunroof it is just fine but the little plastic thing that springs up in the front is what redirects the air on hers, pull it down and you get the same feeling.

 

Just crack open the fronts, crack open the sunroof (if you have one) or the rear slider (if you have one)......
