6th gen si. OEM halfshaft and a Napa axle. I used a new OEM circlip when installing, popped in fine. Was trying to troubleshoot a vibration on acceleration issue and wanted to swap the axle, and this mofo wont come off no matter how much I hammer on it with the slide hammer. I had a new halfshaft and another axle, so I just removed and replaced the whole assembly but I would like to try and at least salvage the OEM halfshaft.

I literally have this thing bolted to the floor and whaling on it and it wont budge. Any tips before i trash the whole thing? my arms cant take any more
