I’ve replaced the thrust arms in addition to the upper A arm. Also had toe aligned close to zero, ~.02 degrees in.

I suspect it could be underinflation of tires or bad suspension links but I wasn’t surprised to see the amount of inner tire wear I saw with about -1.5* camber in front. I think -1* will be a good balance of wear and handling.
