This isn't my truck but this happened to someone that brought theirs out to King of the Hammers the past few days. The rear-steering tie-rod broke. Supposedly the inner bolt to the rack is the culprit but I don't have the full details nor any extra photos.

Either way, sounds like the driver was having a good time and pushed the truck to the limits to try and find weaknesses. Mission accomplished?

Edit: Looks like the truck belongs to the Unplugged Performance team.

I can break things too! - Let me try! - No really, I just have rough hill or two to climb, and 4 wheel drive is sometimes needed to be engaged.

Yes, it's Unplugged Performance's Cybertruck that they've been hooning out at @KOH. A bit more details -- it's on stock factory suspension, but they added their wheels and bigger tires. Guess they found the limits of the factory suspension.

Awesome! Looking forward to aftermarket options from UP.

There's two threads of this now.

If it was the rear steering assembly it might have the same cause as when the rear wheel comes undone on the crash test video.

Having the wheel offset further out can't help.

Unplugged and unhinged.

Yea, pushing the rotational mass outward can only create more leverage on all the arms and links to it. It's worth noting that typically you want the CV axle to be the weak mechanical link in an independent suspension because those are real easy to fix on a trail.

That's a concept I'm very familiar with. I have 40" tires and long-travel suspension on my Toyota Tundra:

Definitely planning on at least putting 37s on the Cybertruck without increasing the offset too much.

Did they slam into a rock or something? I've put large off road tires on vehicles and beat the crap out of them off road, no stock steering components broke.

Yeah also doesn't help aero or range pushing those wheels out so much. Slimmer trails are also a problem if they are heavily rutted.

I'm a bit concerned that rear steering assembly is under specced given how it also snaps in the front crash test. I haven't seen a rear wheel do that before, and I expect with a full load forces on the rear will lead to a similar result.

The front upper control arm also looks too lean for my liking. Might need a rebuild, which is sort of a shame.

Like your Tundra btw, don't see that many modded like that, let alone many Tundras around here. Tacomas everywhere though...

They are testing to make it better with suspension kits owners can buy.

Yep by first intentionally installing wheels with the wrong offset to snap it off first?

Even if they build some superior parts, will the next structure up the chain be able to handle it?

I seriously hope Tesla done their due diligence on off road suspension testing.

It's seriously looking like there are some issues.

More testing is needed not a huge surprise since it is so new.
