Split pin seized in stub axle

I have a rear stub able with a seized split pin.

Any tips on the removal?

It's been soaking in penetrating fluid for the last few days.

Maybe just shear the pin off when you remove the rear hub nut, then punch the remains out of the axle and replace with a new one?

I was thinking about doing that.

Lordy, surely the right sized parallel punch and a lump hammer is no match for a whimsy split pin...

If the split pin is seized the nut may be as well, (usually caused by running without hub caps), try shearing the pin otherwise drill out with a smaller drill first. Drifting tends the splay the top of the pin in the nut castellations.

I see what you mean about them splaying which is why I chisel the ends of first, this way the full force of the hammer is acting upon the pin itself. It's only surface rust, plenty of Weetabix and they all shift sooner or later. :ok

If the nut is seized then no amount of leverage will free it, not even a 6 foot scaffold tube with a heavy set gent bouncing on the end of it. I had one that was resisting everything, I tried a dewalt (18v) impact wrench which had zero effect, then tried a Snap-On (18v) impact wrench on it and it spun off easily. The point I'm making is that if a nut defeats you, call upon a garage that has such a tool and you'll save yourself a lot of blood, sweat and tears as well as disappointment. For beer money, I'm sure any mechanic will be happy to oblige.
