I had that happen to me on a Riveara. Parts store sent the wrong axle. It went in just fine but would NOT come back out. I tried my 3 foot prybar, hammers, rubber mallets, my full arsenal from my tool box. NOTHING WORKED!!! I ended up taking the cv joint apart and pulled it out with a slide hammer after welding a rod to the tulip. What a bunch of BS that was. I lit right into those a-holes at the parts store for that. You have to be carefull pulling on the axle though. You can pull the cv joint right apart if your not careful.
