Two tips, I use a heat gun to warm stuck items and sweat penetrating oil (PB Blaster) into the gaps. There is a magic heat range where you can see the oil bubble into the gap as it penetrates, it is before there is any smoking but not much. Tip two is to tap it on tighter around the perimeter which frequently breaks things loose and with surface imperfections causes the stuck part to wobble up, then followed by normal wedging it out.

Edit for one more tip. The wedges that you can buy for hammer handles installation can be sharpened and tapped in around the base perimeter

My late BIL was a tractor mechanic for 50 years. He used to heat stubborn parts up with a torch and yell, "Shock the shaft!", then start hammering away. :)

I have had the unpleasantness a few times. The knife trick is always the one I use and it always worked for me. You need a knife with a rather thin blade, maybe a fruit knife. Then you carefully hammer it between the crown and the race and once it is stuck you carefully apply some pressure in all directions, just don't break the knife. Switch sides. Eventually it should get loose.

Thanks for all the help! I had a whole list of steps to try. I started with the wire wheel to smooth the steer tube so it would move easier if I got it loose. 5 seconds in with the wire wheel it popped loose! I feel stupid. I wrestled with that thing for 30 minutes last night, didn’t move an iota! So.. all done. I’m going to sand out the inside to give it a little more of a gap to accommodate for the paint. Thanks for all the help!
