As you can see, the whole rear end is pointed right. I've stopped driving it but haven't torn into it yet. Do you think this would be a loose differential mount or something else? I'm probably going to be buying the rear end kit from MC2, but I want to have a good idea of what I need to actually fix while I'm in there.

Perhaps the beam mounts have shifted? The diff itself would not affect alignment since the CV joints in the axles would take up any Left/Right difference in position. Installing a bushing kit will likely/hopefully solve your issue.

Possibilities:

Bent/out of round rear wheel. Or wheels.

--Check wheel run out


Corrosion on hub. Or hubs.

--Remove wheel; thoroughly wire brush hub face of all corrosion/crud.


Corrosion on wheel hub face.

--Thoroughly wire brush wheel hub face of all corrosion/crud.


Hub and wheel mating surfaces must be free of all corrosion/crud build-up.


Worn trailing arm bush(es).

Mine was MUCH worse. The car was "mint". Zero rust.
I suspect some ham fisted Juan Fangio wanna-be bounced it off a curb or 3 at some point.
It was actually crabbing down the road.

This was after the beam mounts were done with black Urethane, bushings too, and MC2 diff mount.
The semi-trailing arms and pickup points are pretty feeble.
I shimmed the heck out of the carriers, and after a couple more trips to the alignment rack, all was well.
It's not a hobby, it's an obsession!

I drove it around the block a few times today and noticed if I jerk the wheel hard enough right, I hear a thunk and the car will drive straight until my next left turn.

With that much play, I'm sure I will figure it out pretty easy once I can get under it. Gotta get my blue one back on the road and out of the garage before I can do anything.

If you're hearing clunks it should be something fairly easy to pinpoint...
