I have seen a 25K old Puma with a front differential cross pin facing imminent failure, Front diff developed some excessive backlash and on inspection the cross pin had flogged the carrier to an oval shape already, and was loose, with almost NO offroad use, so this wouldn't surprise me that one failed completely, and at highway/ road speeds WILL take out a crownwheel etc etc. I would be getting Ray to make a report on this, I would say based on what I have seen even with the limited amount of these vehicles I have come in contact with that it is going to be not all that uncommon in the future. This differential was replaced immediately by our local dealership.
