High pitched noise from engine!! Help!
Howdy all, this noise is driving me nuts! I have a 2002 F150 , 5.4 , 30,000 miles. At around 60 mph - steady driving - I get a high pitched noise from up front. If I feather the gas peddal or let up on the gas, or even speed up , the noise will subside until I return to that magic speed. Soemtimes it will do it at lower speeds. I can't stand it. please help! Huge thanks , Dan
