Blake,
I can't be certain, but it looks like the front left axle snapped off at the steering knuckle?
If you look closely, on that bottom pic with the purple spring over a threaded rod that acts as the suspension - I could swear I see the remains of the front axle inside the outline of a hex nut that was welded to the steering knuckle. If so, and based on the suspension design - I'd be willing to guess that "axle" was either a piece of high strength steel threaded rod, or some form of a modified high strength hex bolt.
Have you removed the remains of the broken axle from the wheel assembly yet? If so, what does it look like? It could provide some clues..
As for repairs, you may need to disassemble that steering knuckle assembly as much as you can to see how it was fabricated. That will dictate the best way to do the repairs...
Also you didn't tell us what happened to cause that axle to snap off - but my experience is the either driver caught the edge of something at speed, or they went airborne and came down hard on that wheel.. or a combination of the two. It takes a bit to snap hardened steel like that...

Whatever happened, I'd be looking at the rest of the suspension / steering for second order effects - because I'd suspect you have some other stuff that got "tweaked" in the process...
So take that steering knuckle apart, take some pics - post them - and let the group offer up some advice...
