I whacked the tire wall at VIR fairly hard with the wheel taking most of the impact (it seems)

What would be the most likely cause of having a screwed up caster? Lower control arm? Upper control arm?

I'm thinking the lower control arm is the most likely culprit...but I'm not l00king forward to replacing it ($$$)

 

If it's enough to knock your caster out of whack, you can probably see something slightly bent. If you can't, pretend you never saw the caster measurement and just drive

Worked for Mid-Ohio

 

I did the same late last October. My LCA was the first thing that was evidently bent. I replaced it, and it turned out that my rear cross beam was bent, along with the radius rod for that side (which directly effects caster). I've replaced damn near everything on that side thus far and I'm still struggling a bit with trying to get back to factory specs.

I may be crazy, but at one point it seemed that installation order affected my caster. When I installed the swaybar onto the LCA before the radius rod it seemed to 'drag' the LCA towards the back of the car. When I installed the radius rod first it seemed to correct the situation. Of course, I drive an Accord, and this may just be symptomatic of something else that I haven't replaced quite yet.

Have a look under the car to see if you bent the LCA. I'd bet that it is, especially if you hit the wall with the wheel turned. Oh, and I've been driving it with a degree or two of caster off for a bit
