Looking for help, or ideas.

There is a 60s video showing the darts handling. When the dart hard corners the tires and wheels lean excessively. Yes there is body roll compounding the angles but it's there. Also I have seen dart drag cars coming down from a wheel stand and the front wheels are wabbling all over the place on impact. Yes more extream forces at play.

In a video of a Corvair corning they had a camera looking at the front tires the wheel is leaning excessively and the tire is almost rolled up under the wheel

Again extream forces at play.

I had a solid front axel 56 Ford pickup.
The tierod broke. While moving forward one wheel would turn out and the front of the truck would rise then go back to center and fall. Quite a wild ride at 5 to 10mph.

This is just my opinion from my knowledge base not having seen the car in person.

Yeah but this is literally a car in a driveway being rolled back and forth. There are no extreme forces.

Something is broken, or moving around.
