It appears that the outer bearing inner race ground down the end of you spindle from the first picture. Can you ger any movement at all?
So I bought a cheap puller at Harbor Freight and was able to move the inner race all the way to the edge of the spindle but now it is truly stuck.
I tried lubricants, heating with a cheap torch but it just wont budge that last millimeter.
I started a blog and posted my whole saga with photos of my puller setup.
