I've soaked a couple with a 50/50 solution of acetone and automatic transmission fluid. Mix it, drop some on the shaft/nut and let it soak. I usually put a few drops on a few times a day and do it for a few days! Because I have time to wait, I've never failed to get it to release.

Machinist's Workshop Magazine recently published some information on various penetrating oils. The magazine reports they tested penetrates for break out torque on rusted nuts.They are below. They arranged a subjective test of all the popular penetrates with the control being the torque required to remove the nut from a "scientifically rusted" environment.
Penetrating oils ........... Average torque load to loosen
No Oil used ................... 516 pounds
WD-40 ..................... ... 238 pounds
PB Blaster .................... 214 pounds
Liquid Wrench ...............127 pounds
Kano Kroil .................... 106 pounds
ATF*-Acetone mix............53 pounds
The ATF-Acetone mix is a "home brew" mix of 50 - 50 automatic transmission fluid and acetone. Note this "home brew" released bolts better than any commercial product in this one particular test.
ATF-Acetone mix is best, but you can also use ATF and lacquer thinner in a 50-50 mix.
*ATF=Automatic Transmission Fluid.
If you cut it off you can find aftermarket steering wheels on line. Just be sure to get the correct splines/taper for your application.
