ER-16 bearing doesn't fit on steering shaft

Thanks for the ideas. Can't do much heating... this is a sealed bearing with rubber seals. Doubt I'd get the required expansion with any reasonable temperature (200F or less) - this part is only an inch across.

My car WAS a column shift, but all that stuff (plastic bushings, shift tube, linkage) is removed...

I know I can make the shaft smaller, but I would rather not disassemble the column again. Once (to shorten it, and remove the "PRND21" and shifter nub from the collar) was enough ;)
