Wheelchair repairs are usually a pain, but this thing has been whipping my butt more than the usual. What you are looking at is the stem bolt of the front mono fork assembly from a TiLite ZR Series 2 manual chair.
The stem bolt is factory welded into the titanium frame. On to that is bolted the fork assembly with two bearing cassettes inside the housing. Well, the thing was freezing up and trying to veer me off into walls with each push, so I took it apart to change the shot bearing cassettes. They were oozing, gooey messes; I waited way too long to do this. The upper cassette wouldn’t come off. It had to tear apart the cassette to get to the inner race so I can remove it, and it still won’t budge. It’s fused to the stem bolt.
I’ve tried getting some WD-40 in there to loosen it, but nothing doing. At this point, I am thinking of picking up some lock pliers so I can really put some arm strength into it. After that, I don’t know.

You need a small bearing puller.

I don’t have any advice other than Vise-Grips, to be honest. If I had access to it, I might try a cold chisel and hammer to split the race, but only if the Vise-Grips failed.

There’s an idea. I wonder if I can borrow one.

That’s kind of where my mind was going, too. The only thing about a chisel or similar cutting tool is that I’m worried about damage to the stem underneath. If I ruin that, it’s game over.

Most auto parts store should have them for rent. :)

The concern would be cracking the stem loose from the structure, IMO. It’s like a trailer spindle in that even if you scarred it/left a chisel mark in it, it wouldn’t actually affect the operation as long as it didn’t have the effect of knurling the surface enough to make the bearing too tight to install. I’ve seen more trailer spindles with damage...

That’s a good point, but I still wouldn’t want to gouge or groove it. That usually does leave material sticking up that will interfere with the new bearings sliding on. Then I’d have to grind it down. I hope not to get into that.
