Pulled the third member today. Cursory inspection shows no unusual damage. I might have caught it before it destroyed the ring and pinion. There may still be wear issues, but no bad teeth or no extra metal in the oil. Local shop is going to look at it as soon as I can get an appointment. I'm waiting to hear back from them now. I stopped in earlier, showed them the video above. When I called this afternoon after pulling the third member, they were at lunch.
