Truly a "nut buster" both literally & figuratively. But I did it.
I am truly getting too old for this, but at the end there was quite a sense of accomplishment.
Background: I drove the wife's car (an 8 year old Chevrolet sedan) on the highway for the first time in awhile and heard an obvious speed-related noise. Further diagnosis led to the hypothesis that it was rear wheel bearings. Knowing what that job entails, my major thought was "Oh s**t".
Well, I finally got the old ones off, as you can see below. A combination of penetrating oil, slide hammer, club hammer, freshly sharpened chisels, and jacking screws finally did the trick.
Here is an interesting video of this job and various techniques, all of which fail:

(I personally find this video unrealistic because there is no swearing.)
One important point: For the "jacking screw" method, use grade 8 or better bolts, not the inexpensive ones from Home Cheapo like I did (ref. the stripped bolt in the photo).
