As an update, I had to change the complete lower arms. Couldn't find the bushings. Ball joints were still okay, but I replaced them as they came with the arms.
I can't find any problems with the wheel bearings - I tried pushing, pulling, etc. I spun the wheels and the cv joints sound good too.
The passenger wheel does seem to have some play at the tie rod ends, but the outer tied rod seems fine. The play seems to come from inside the boot at the inner tie rod. Are these replaceable? I see them listed on RockAuto and O'Reilly's, but not at GM
