I'm practically new when it comes to this subject. I did a 4 Wheel Alignment this morning.
While the tech guy was doing the alignment, he first notified me that the left caster cannot be aligned. He asked if I was in a accident before, and I told him the truth, which is "No".

However, a few months back on the freeway, I drove through a big ripped tire cut in half (truck/trailer size). It wasn't round anymore, it was horizontal flat. I couldn't switch lanes because there were cars on both sides and couldn't do much about it.

Not sure if that made an impact on my car when it comes to wheel alignment.
Anyways, I just want to make sure if hes telling the truth and he did my alignment correct. I have uploaded the results. Take a look at it.

Any help is appreciated. Thanks.

Hit that tire with your left front wheel?
Reduced caster does seem like it fits with something forcing the wheel back.

From the lower control arm (on that side) there's control rod that goes forwards & attaches somewhere in the car's structure. Have a good look around where that attaches, compare with the opposite side. Hitting the tire would've pulled on that rod pretty hard.

I'm only guessing, but it might have damaged the rubber donut bushings where that rod attaches? Or maybe it bent some of the metal structure up there? That seems like a place that's not RIGHT THERE in the suspension, and might be overlooked by the tech.

I think this is more of a suspension question so I'll move it over there.

 

Looks to me like the LF is pushed back. Sometimes you can loosen the front beam, and pull it forward to fix that. Otherwise, it's most likely has to be replaced.

Disclaimer: without seeing the car, it's impossible to know what's bent.
