Thanks so much, that is good to hear! To be clear, I only cut directly into the bore of the steering knuckle because I completely messed up on the directions. I failed to confirm what exactly had been removed by the pressing out of the bearing. Once it dawned on me that I had already removed the outer race that had remained on the hub, and saw the inner race and the bearings already removed, I ran into the house and grabbed the new bearing out of the freezer. That's when I realized I was mistakenly cutting into the steering knuckle itself. Ugh. I will try deburring with the dremel next. Thanks for the tip on the heating and cooling, will try that next time.

Just for clarity on my end, I take an air hammer to the back side of the inner bearing race. This removes the inner race and both sides of the bearing. The outer race stays in the spindle. There is a point in the outer race that separates the two rows of bearings. I start the torch at this point and slice across the outer race, but not through it. Then set the air hammer on that point and a light tap tap removes it.
I imagine without the air hammer it may be simpler to pull the spindle. The outer race can then be used to draw the new bearing in using threaded rod/bolt and washers.
The more I find to learn, I find there's more to learn

By the time I realized my error I had already cut a decent sized groove into the bore of the steering knuckle.
Please, please, please, someone tell me that I can just sand that a bit, or fill the cut with a little jb weld, and proceed to press the new bearing in. The circlip will still fit.
Eh, you're probably fine. Use JB Weld, or don't, I don't think the bearing will care much. Press in a new bearing and motor on. Try not to work hungry or tired again.

Everybody's got to eat their share of **** sammiches, just remember the taste next time.
If you post a question, post your solution!
