I saw a claim that this was just disassembly to do the repair. Why they would need to remove upper balljoint to change a bolt associated with the tie rod I have no idea.
Of course maybe it's all a lie and the nut just fell off. I don't see any sort of retention mechanism on it. I guess I'm old school but I like castle nuts on my ball joints!
Video showing rear suspension. Maybe the threaded rod is the "bolt"? That's what I would assume would break first but no idea why you would remove the upper ball joint to fix it.

Awesome! They don't mention the countless breaks involved in offroading. The more CT "dirt" the better, by the time my reservation comes up Elon will be paying me to own it.

I'm pretty sure all Teslas are cotter pin free. The best part is no part.

American vehicle manufacturers have been using nylon locknuts on steering and suspension parts for a while now. They are 'single-use' nuts; service manuals explicitly state they must be replaced every time they are removed. Because screw the technicians, apparently. Now you can't just grab a universal cotter pin; you have to order and obtain an assortment of specific nuts every time you work on the suspension.
I also don't know why the upper ball joint was separated. The rear tie rod is disconnected/missing/broken? but it shouldn't be necessary to separate the upper ball joint to facilitate tie rod repair.

That all looks stronger than the tie rod itself. I'm going with one of these two:
- They removed the nut holding the upper ball joint, didn't replace it with a new one, and didn't torque it to spec. They're being cagey because that's not a good look for a suspension shop.
- There is some sort of Tesla design flaw or assembly problem and they don't want to be the ones who publicize it. Maybe so they don't upset the fanboys or because they want to be the first to market a solution.
Details, but I still can't see the break

The plot thickens. Still no pictures of a broken tie rod or broken bolt. There’s a picture of an intact tie rod and pictures of a nylon strap bolted to where a tie rod once was.
Why not take a picture of what broke?

It's possible that to keep weight down Tesla used lighter duty parts for the Rear Steer than the Front Steering parts. These parts couldn't handle the side loads it was subjected to. I wonder about the Rear Wheel Steering when you are in a Hole or Mud and you turn the Steering Wheel and the Steering can't turn the rear wheels. Will the Front Wheels still turn or will something break in the Steering?
You are out with a broken Truck people are going to take pictures and make comments. Same thing with the New Ford Broncos when they break.

Doesn’t seem like this bolt would shear before the tie rod bent. On vehicles I’ve seen the bolts holding the steering rack on are huge. I think the rack would break in half before they break.

From the InsideEVs article:
"...and on the second day, a stock bolt from the Cybertruck’s rear-right inner tie rod broke, rendering the car undrivable."
So it was the inner bolt.

I find it hard to believe, too. You'd think the outer tie rod ball joint stud would shear off LONG before the inner bolt would shear.

And the tie rod would bend/break before either.
New hypothesis, maybe they mean the bolt went missing so it must have broken off. Haha.
Or it backed out halfway and then broke (I still don’t think that bolt would break in this case)

From the twitter post:
"That one bolt broke is not concerning to us at all, and we wouldn’t hesitate to push even harder next time."
Yeah, OK bro. I happen to like vehicles that steer in the direction "I" point them. Kind of a self-preservation kink I got going on.
