Right, I was just wondering if someone could confirm that the upper A arm and ball socket were actually aluminum. It seems a very unlikely material choice for that part to me. I just don't have a tesla to go check on myself. Honestly, if the boot failed and the guy drove through saltwater, the steel of that part still shouldn't have rusted that badly. My armchair guess is that Tesla or their supplier didn't spec it wrong, but got a bad batch of metal in there that was improperly treated or alloyed.
