I have a 98 F-150. I started noticing something like that when it was fairly
new. One or two years. I think they call it the idler arm, as I recall.
Anyway, there, on the 98, there is 2 grease fittings. I got out the grease
gun and shot grease into them. Stopped the noise. If I don't grease them
every 6000 miles, the noise starts again. Having said that, for safety
reasons, don't rule out what the previous commenters have said. Good Luck!!!
