Im tring to track down a ver specific chirping sound. I can hear it mostly on the left when i am driving. I sounds like a plastic edge rubbing on a metal surface. I have had this problem for a year and Im going nuts tring to find it. Is there anything with the 2002 4x4's that makes that kind of sound after 85k? If yall have fixed any kinda rattle on you truck tell me. IM at the end of my rope on this one.
