First off let me apoligize for posting an Excursion question in the truck forum. With that sais. I just purchased a 2001 Excursion 4x4 with the V-10. Truck has 90,000 miles on it and is in great shape. The only problem I have with it is a crumpling lose something sould in the driverside firewall/floorboard area. Almost like a lose body mount sound. Any ideas ?
