dealer says they can't find source of squeak from front end. It has only gotten worse. Mostly does this when I turn the wheels , but even if I go and sit in the truck or get out. I have talked to severals others with close to the same years with the same noise, but have not gotten fixed(i have a 1994 f150 flareside) I need to fix this soon has I tow my Jeep behind it.

help!
