As others have mentioned, I don't think the pry bar will help

Yours sound like it might be corroded so you have to break the corrosion through impact first.
Have you tried a pickle fork right where the axle goes into the oil pan / disconnect housing? I imagine the tapered fork with a solid hit with a hammer will be enough to force it loose?
When i did mine, I removed the spindle so the CV shaft wasn't connected to the bearing at all. I wasn't sure if there would be enough 'play' for the CV axle to pop out of the disconnect if it was still connected to the wheel bearing. A lot of of people recommend leaving it connected and just undo the top ball joint, but I disconnected everything.
1 more suggestion .. if you're using the drift bar method, try and keep the bar as horizontal as possible. You want all the energy from the hammer/mallet to be transferred to push the CV axle outward, not upward.
