UGH! Well I found the source of the clank. I was able to get my wife to reproduce the sound while I listened, and realized the sound was actually coming from the REAR passenger wheel well, not the front. A quick check and voila - a ΅’k!ng bolt missing from the rotor mounting bracket in the back. I don't know how the heck that could've happened, I can't even remember the last time I would've had those off. Or if it was even me who did. Maybe it wasn't torqued to spec? Anyway, that is solved.
I also took it for a longer test drive and couldn't replicate the wobble. I guess I will attribute that to either the loose lower castle nut, and/or the 1/8th of a turn of the one track bar bolt, combined with the utter lack of any effective steering stabilizer? Anyway, I'm probably going to check the remaining bolt holes and bushings this weekend to be sure. And maybe order a new steering stabilizer if all looks well?
Anyway thanks to everyone who chimed in, I'll update if I find anything else.
