None that I've ever seen. If you don't want to try a bigger hammer, I suppose you could rig up a big C clamp with some kind of relief on the inboard side (hardwood with a drilled hole, or large washers). Get the C clamp as tight as you can without destroying it, and tap on the hub near the stud.

Me, I'd try some PB Blaster and a bigger hammer. In desperation,maybe some well-directed heat without frying the seals.

Good luck and let us know.
