Ford has produced several different trucks over the years, with the F-150 being the most common and popular truck. In addition to the F-150, Ford has produced the F-250, F-350, F-450, F-550 and, recently, the F-650 and F-750. The F-150 and F-250 have the same headlamp assembly replacement process whereas the rest of the F-Series trucks have a different process. Both procedures require a Phillips head screwdriver and a socket wrench. These procedures are for the eleventh generation F-Series trucks produced from 2004 through 2008, but the idea behind the process is the same for all generations. The differences lie in the number and location of the screws and bolts.
