Before I'd go through the mess of removing the inside connection, I'd take off the axle nut and push the axle out of the hub. I used a rotary hammer from Harbor Freight with 20% off coupon. I believe it was $80 or $100. Used a bull nose chisel with it. Not too bad considering it can be used for future work (or the other side!)
