I just removed one today and it worked like a charm. I use the grease method and I used a 1/4" drive 7/16" (if I remember correctly) craftsman socket. Fit the hole perfect. Put a long extension in the end of the socket. Packed the end of the crank full of grease and 3 light hits with a BFH it was out. I did repack the end of the crank between hits. No damage and not much effort, just a little grease to clean up afterwards. I have used this method several times with the same result.
