Hello 1983MacGyver When you pulled the front axle off the 1986 4x4 1910 Ford Tractor. You must have removed the 4x4 Rigid Tube driveshaft. was there anything inside the tube other then the coupler gear in both ends of the Tube? My frame broke and the driveshift fell off in the snow so I am not sure if I lost any parts. Do you have a picture of the removed rigid tube and drive shaft?
