Put another hammer on the backside of the spindle just beside the one you want out...and give er a good blast with the hammer...they are just splined to hold them in place. If not you could drill them in the exact middle just dont drill too big..keep your drill slightly smaller than the stud. Should be able to beat them out though. Do yourself a favor and wear safety glasses...Ive seen particles fly off on those hardened steel things before.A good heavy hammer as a brace and a good solid wack and they should just pop out. I would only use heat as a very very last resort.
