Funny little update:
Driving around the last few days and I thought I was going crazy, but my steering wheel started to lose the ability to stay centered, and started pulling to the right under braking... wtfdotcom?
I pulled the front-driver's wheel and started poking around, and found the UCA rear/right-side nut was loose-ish... certainly not the ~137lb/ft the manual calls for. I could see bare metal, and it looked like the camber plate had slowly moved over time/hitting bumps. I put a long wrench on the bolt-head, and cranked it back up until the plate aligned with the marks in the mounting tabs on the frame, and went for a drive.
It was 90% better, and took another tweak to that one camber bolt to get teh steering and braking centered again. I checked all the other nuts/bolts on both sides, and they were all gootentight, so it was just that one loose camber bolt messing with my sanity... never going back to that shop again.
