| Description of the problem | Differential lock activates by it's self. Light comes on instrument panel showing rear axle locked. Rear axle locks up at speeds below 20 mph. If stopped at a light or sign your rear wheels will drag as if the brakes are being applied. It can happen at any time. If going over 20 mph some times the instrument panel message center lights up and says you have to slow down below 20 mph to apply rear differential lock. Happens mostly in 2wd. This has happened for over 6,000 miles. Can be on dry pavement or rough surface. Have noticed that the 4wd mode switch on dash will seem loose and the knob will pull out if you hit a rough road surface. I have replaced the mode switch at my expense (1) time at my expense p/n cl3z-14b166-ea. Dealer and ford still trying to figure out problem. This causes vehicle to loose communications with obd circuit and several other modules. Not allowing system to download codes or to update parameters. |
