High Pitched Squeel

I have 10,000 miles on my 2011 F150 5.0 and have had the whistle noise from day one. Had it back to the dealer 3 times and they claim it is normal, I contacted Ford and they agree with the dealer, They basically said sorry for your luck but there is nothing we can do, The computer is not telling us there is a problem (WTF). Same symptoms; the whistle can be controlled by the gas pedal though out the shift cycle regardless of RPM. After reading this thread i plan on looking into the seals this weekend, This makes the most sense since the whistle is loudest out of the drivers side window. Thank you for all the posts, This is a great site!
