Your focus is on the knuckle. What does the sub frame that it mounts to look like?

 

As I mentioned in my last post, I have no real way to figure out what is bent or what isn't without purchasing a known good part, pulling off the current part and comparing, and even that isn't 100% accurate.

I would just take it to a shop to get it inspected, however, after being to several already and bringing up the subject about that corner, every shop has given me the same relative answer saying that just putting it up on a lift and looking at it for hours will do nothing as you will rarely be able to visually see what is wrong.

Just out of ideas and praying that it is the knuckle bent and not the chassis or frame of the car...

 

the sub frame isn't likely to cause such an issue... not impossible but it would show up in an alignment.
