So I ran into this same problem trying to put new bearings in my clutch release arm - couldn’t get the old ones out and really mangled them trying different things. Came in from the shop to consult the collective wisdom of the board and found this thread. Headed back out to the shop sulking.
Then a light came on in my little pea brain, and I figured I had nothing to lose. So I fired up the mig welder and very carefully laid down a couple of small beads in the id of what remained of the bearing outer races. Then, using a suitable drift, gave a few taps against these beads and presto - the first one almost fell out. The second one was a bit stubborn, but ultimately came out with a few good whacks.
Pressed the new bearings in and installed the arm with a new spindle - ready for another 100k.
Chalk one up for the good guys! I hope this helps out somebody else on the board facing the same problem.
