Need to get this drivers side shaft out of old hub. Went got FWD puller Autozone fits 5 lug pattern and pushes center shaft. I worked it a little bit and still stuck. Thought I better ask before I start smacking shaft harder with nut on. Can these get stuck? Been soaking in PB blaster. I thought maybe I need to loosen up three star nuts to give some play then smack center shaft nut on end?
