heard a faint clunking or tapping Saturday when I parked it, thought it was a tire or rock in the tread the way it sounded. drove it to work Monday and same noise, didn't get any louder, on the commute home however, bang! lots of clunking and you could feel the resistance , thought it was the drive shaft the way it felt. Could have kept driving but was scared something else would have broke so I got a tow home
threw it on the lift and here is the result

housing is intact, but there's a lot of play and likely many missing teeth. new unit in route from a low mileage wrecked car. axles out and look fine. guess I'm driving the truck to work this week
once the new one arrives and is installed ill crack the case on the old and display the carnage
