DA steering wheel wont come off. Help

OK I hope this is in the right place, So when I bought my car it had a da steering wheel on it, I dont want it anymore and cant get it off. It doesnt/didnt have a nut on it which I figured out recently. Tried to pull it as hard as possible and even my mechanic friend tried to no avail. Any ideas I really want this thing off.

I've only had to use the steering wheel puller twice before and one of them was so stuck it broke the c-clip inside the steering column. The steering wheel would have half an inch of freeplay up and down.
