Stacey, Welcome to the best and friendliest F-150 site on the planet!
In regards to the question. Possibly when spinout failure (where one wheel was spinning at some point in diff's lifetime and suddenly the wheel caught instant traction on a solid surface). This example of failure could have iniated tooth distress on some of the gears in the differential nest assembly--which fatigued and failed at a later date.
Another possibility: shock-load, or vehicle overload. Also, in an OEM track-lock, if the clutch fibers or clutch steel plates failed (completely went away or desintergrated), the same could result in the type of failure you describe. Good luck, gearman
