The spindle pins are such a pain in the ass. Something I found really helped was getting a medium-sized tub, and then filling it with about a gallon of 50/50 ATF and acetone. It's like penetrating oil on steroids. Set the side of the strut/control arm assembly with the spindle pin into the tub and let it soak for 2 or 3 days. I stopped breaking threaded rod after that.
