02 F350 Crewcab Long bed PSD
recent trip down road, had two people in back of crew cab and when they would roll down the back window there was an unplesent ear hurting sound. the best way to explain is kinda like sonic pulses. at first i thought it was just the truck noise bouncing off the gurad rial but it continued after passing the end of the guard rial. roll up the window and it would go away. roll down the front windows and you would not hear it or feel it. is this just some type of turbulance created from such a long truck?

 

I have the same problem,I think its just the nature of the beast.
But when u do hear that noise just roll down the front window just a bit and the noise goes away..

 

I've been in Explorers and Expeditions and they all do the same thing.

 

Yeah, its just air turbulance. Nothing practical you can do about it.

 

Couldnt have said it better my self(cause i never knew what to call it ).... I have always heard it in my beast(or any car for that matter)... But only if the windows cracked... Its annoying alright!

 

My last 5 vehicles have done this and they were of all makes so Ford is not the only one.

 

thank you all very much, i was a bit concerned, i am glad to hear that it is infact just a bit of turbulance, thanks again.

 

when my dad was test driving a BMW 740il, he i put my window down some, and the lady said that because the car was "sealed" so well, that the pressure couldnt escape, so it made the sound. i just crack all 4 windows and there is now problem. if you have the right rear down, it usually works to crack the opposite (front left) window.

 

A friend of mine had a Chevy CC Dualie that would do it. Both my CC LBs do it!!

 

all of mine do it it is normal. just crack another window about 1/2 ''

 

I think it's about the same as a whistle, only a much, much, larger volume in which to resonate. Thus, a much, much, lower frequency.
