Today I had my yearly 2003 Diesel Excursion inspection by the Peoples Republic of Massachusetts. (Christ, they even measured the diameter of the exhaust pipe). The technician said that my ball joints were starting to wear. He stated that this is typical for a Ford truck - is it? It is a 2003 with 58,564 miles. He said that next year they would have to be replaced - anyone know what that will set me back? Thanks.
