    Have developed some kind of persistant knocking sound above driver seat between headliner and roof. can feel the knocking through headliner near the overhead light.

    Its gotten worse and is driving me batty. Company truck so I cant desyroy it to make it stop. but am seriously considering it. #### rough roads in Indiana, Michigan and parts of Ohio.........

    What could have been rattled loose up there?

    The inner roof support weld may have broken loose, or a wiring harness clip/bracket is rattling around up there.

    A dead mouse or rat is up there.

    The only way to find out is to carefully remove the headliner and look.

    Sounds like an air line for the horn. Had an old Binder that did that.
