Very likely due to the several studs around the bottom of the housing being beaten into obliteration on that trip. Or the pinion bearing taking a beating. It survived Mardi Krawl though. I think I chipped a small tooth sometime around then, and it became a larger issue in the last month when that tooth eventually got chewed up and spat out by the rest of the ring gear.
Here's the tooth that stuck to the magnet in the drain plug.
Here's the rest of the teeth resting on the bottom of the housing.
Here's the ring gear.
