This is on an '04 Mercedes. I've tried a dead blow hammer from the back but there isn't enough room behind the rotor to get a good whack at it. I've sprayed PB Blaster to the hub. I heated the hub area with a propane torch and then spayed Freeze-Off at it. All the while I have that old time brake drum puller attached. Is there a heavy duty version if that puller? It says to only finger tighten the center screw so it won't do a whole lot. Any other ideas?
