problem #4

While driving in a snowstorm the shifting fork on the front differential broke disengaging the 4 wheel drive which caused me to loose control. I have found out today that this has happened to several people I know and that Ford has redesigned this shifting fork. I believe this should be a recall. If anyone had been next to me when the fork broke there would have been an accident.

2003 Ford 150 ext cab 4X4 truck was being driven at approximately 40 mph with a light load. As the truck was shifted from 3rd to 4th the drive line broken in half and began pounding the undercarriage of the vehicle damaging the fuel tank and exhaust sytem. The driver claims the clutch was non responsive and there was a strong smell of burned clutch has the vehicle was stopped. Ford rep is claiming damage is the result of abuse and/or prior damage to the driveline based on photographs supplied by dealership (the Ford rep did not physically inspect). The dealership has no opinion of why the failure occurred and has claimed to have never seen such a failure. I do not feel that there is documentation to support Ford's position and they are simply attempting to avoid a warranty claim. Of even deeper concern is the possibility that other F150's could experiance the same failure which could result in injuries and/or loss of life.

Drive train wine between 47 mph and 55 mph in my 2003 F-150 supper crew. The Ford dealer replaced the rear drive shaft but the problem still existed. Dealer called Ford and Ford said because I have a sliding rear window, tonneau cover and 3.73 rear end gearing these items are causing the wine. The Ford dealer said that if tried to run this problem through warranty again Ford would deny it. The dealer also said I should take this problem to another dealer.
