Passenger CV axle seized

I tried for hours to remove the passenger CV axle. I had a neighbor help me. I got everything off, except the CV axle bearing. I can't for the life of me getting it out.

We used a slide hammer and all it did was get the inner joint to come apart. We tried using different things to hammer the other side of the bearing, but there is not enough clearance, even getting the engine mount off would be difficult, and the exhaust bolts are all rusted.
