how do i remove the steering column?!?!

If a split pin is bent a little it can be a biotch to get out. I've been there done that in machinery applications Common drill bit doesn't work well either. The pin is a very hard steel and the split in it kills the cutting edge of the bit.
It would take a wreck to bend one in a car though. With any luck, a long drift, and a shop hammer it should drive right out.
