Changed out my loose wheel bearing, and that wasn't the only source of my vibration. Oh well, the hunt continues. Anyway...
To get the rusty, 130k mile old bearing out with the modest tools in my garage, I removed the CV axle, popped the ball joint back together, got under the car and beat on the inside of the bearing directly with a 3lb hand sledge and it came right out with a few hits. Then I reinstalled the CV axle and reassembled everything.
The ball joint is easy to pop in and out with a floor jack, and of course the half shaft just takes a tug to remove. I think this is the way to do it!
UPDATE: My vibration was being caused by a bad rear U-joint, replaced the entire driveshaft with a junkyard find.
