..mmm...a bigger hammer...
I want to point out that to remove stress on components with the "hammer" method, I reinstall the wheel with all five nuts tight and down the car on it weight on the tire...so the mass of the car adds as a lot of momentum to the hub to keep it steady and this helps direct the energy to move the shaft only...maybe you have done that already, but...just in case....
