Anyone else had this problem? what is the best fix for this?

My buddy who is a repo man said all the F150s and Expeditions have this rattle. It is not all the time, just sometimes at low idle, if you hold the shield it doesnt rattle. I was going to rip it off but dont want to jack anything up.

Thanks.

 

Very common on older ones. AC drains of on the one on the pass. side which can in time cause rust. May not be the isues you're having, but then again, a '97 is 8-9 years old.

 

Very common problem as my Navigator started doing it about 3 years ago. I had the muffler shop just take it off as it won't cause any problem. He said it was on there to keep from causing brush fires if 4 wheeling in high grass areas. Well mine never sees the off road (at least intentionally) so it wasn't a big deal to me just to take it off.
