2003 Ford f150 4x4. A heavy snow storm hit northeast on 3/16/07. I had my pregnant wife and three year old son in truck coming back from a doctors appointment. The four wheel drive did not engage. We were stuck for a long period of time. I did some research and this seems to be a common event with the Fords and there shift on the fly 4x4 system. I called Ford and they said they were aware of the on going problem but told me it was my problem. There were no recalls for the system and again stated "it was my problem!" there are many documented occurences yet nothing has been corrected. Truck is going in for repair on Friday and mechanic stated it is approx $500 to repair. The vacuum soleniod and vacuum lines need to be replaced. Ford was also aware of the vacuum problem when I spoke with them. Very frustrating and dangerous with a family relying on a 4x4 when needed.

I was driving down the road at 50-55 mph and my 4x wheel drive kicked on without me engaging it, then by itself again it turned off. The next night I was turning a corner and it did it again, it went on and off by itself. My boyfriend did not believe it and then an hour later he was driving and I did it again. I took it the dealer days later and they couldn't find out what it was . They said they tried to provoke it but they couldn't find out why and how it was happening.

While driving 55 mph the front hubs locked. As a result, the vehicle disengaged out of 4-wheel drive without warning.

The four-wheel drive would not operate properly. The vehicle was taken to a dealer that replaced the parts with parts from another vehicle of the same make, model, and model year. Those parts failed the same day of repair. Please provide any additional information.

At highway speed vehicle goes into low 4-wheel drive.
