Guess what broke... Let's play a game.
Symptom is during turns there is a thud from the rear. It culminated to some violent backlash thru the drive train like it was binding. If rolling, feels fine, if accelerating in a straight line it's fine, only when accelerating during a turn is it violent.
Happens at low speed and low accel.
I'm taking the cover off to inspect on Saturday. Let's see how well online diagnoses work. For Friday I'll answer any questions on symptoms from work.

It's an auburn differential.
It's apart now.
I sheared 2 teeth off a spider gear within the differential. So the above symptoms happen when the innards of the differential seize up. I'm guessing it got stuck on a tooth and binded. It was strong enough to send a pretty nasty backlash through the drivetrain enough to trigger compression of the clutch springs on the hub.
Now the tricky part of yanking the differential out of the housing. It's jammed in there pretty well.
Pulled the carrier, required creative hammering and a 30 ft nylon rope and some tug of war.
I found I actually sheared off 4 teeth off 2 spider gears. 2 are accounted for on the magnet, the other 2 I'm guessing is wedged within the spider gears.

the clutch only made noise during turns, and that was because the tire locked and the differential couldn't turn around the slower spinning wheel so the whole system effectively locked and caused the clutch hub springs to bounce. Pretty violent too, couldn't imagine how bad it'd be if I was trying to apply a lot of power instead of crawl thru a turn
Man i read the title and knew what what wrong, thats exactly what happened to mine, and then completely went one day pulling away from the stoplight and hitting second gear.

That's what mine would have looked at if I kept driving it.
I'm glad I caught mine early. Just a few teeth broken and the material not scattered all over the place, same deal though as the pics above.
