Agree with above, the bolt is probably not going to fit through the hole due to the bearing either fusing to it or wearing on it. Time to get out the dremel tool or hacksaw. I have started replacing my bearings every year or so even if they don't need it because the last time one went, it was a royal pain to get the bolt out. You can get some inexpensive skateboard bearings on Amazon that work every bit as good as the OEM ones.
The great thing is, the parts are all easily available. The painful thing is, the area that bolt is in isn't the easiest to work on.
