So is the camber different (more extreme negative) on the right than the left?
If the camber link is in good shape (as it seems to be) and the cambers are in the same ballpark visually you might want to look at the toe link on that side. A bent toe link could wear the inside shoulder of the tire. I would have the alignment checked to what's what.
These camber links are good and pain-free. (Direct replacement of upper arm/ no modifications needed)
