When I start going the 4 wheel is not engaged and the rear tires spin. I checked all the vac lines and they are all attached. The only work done on the truck ever has been the high pressure oil pump that was replaced by Ford last month. My Buddy down the street has the same exact truck with the same exact problem. Could it possibly be moisture in the vac system causing ice? This has never happened to either truck and I could only guess it is from the arctic weather we are having here in the south.
