I sure hope this video was available to the insurance companies and to the court. I also hope there were no passengers, especially children.

Totally Unreal ! Hope he survived !

She survived. Walked away from the accident.

holy smokes! that was crazy and unexpected. what was the cause ? lost front tire? it was like the car poll vaulted

A Tesla cam captured the event.

The truck had wheel spacers that caused the wheel hub assembly to fail.

When I first saw the video, I thought it was a wheel spacer that let go. I can't believe how high the sedan went up. I'm glad the driver walked away.

I also thought of Wheel Spacers, of which I am not a fan. What I think happened might be a bit different though. I have seen so many wheel separations, many when I was racing in SCCA events. Many times you look at the after wheel separation event and all the wheel studs are sheared off. However we duplicated this in the test lab on the flat track with instrumented wheel studs, (pricey little devils at $5,000 each including wiring to attach to slip rings on the head of the flat track machine. We could turn the wheel on the flat track, (a huge inverted Belt Sander like device with an A frame over it with a hydraulic ram to which is attached a spindle from the vehicle, Ranger, F150 etc. What we found watching the stud strains was one stud let go so the other studs increased in strain as a result and then another stud failed and increased the load on the remaining studs and at that point the remaining studs gave up and catastrophic failure occurred and the wheel left the spindle and crashed into the safety cage around the flat track machine. It happens so fast that you think all the studs failed at the same time, but this is not the case... Analysis after shows two different failures...Tensile failure and then shear failure...

This is one reason I am against wheel spacers. The other is too many joints. Wheel to rotor changes to Wheel to spacer and spacer to rotor...

Okay... I retreat to the flame proof bunker as the Rangers running spacers will start with their no problem with my Ranger rant...

I am not here on these forums as a popularity contest but to give back on 30 years of experiences in the behind the scenes realm of automotive engineering.




Best,
Phil
