Maybe silly question - rebuilding wheel hubs? Options

[CrashTestDummy]

I'm kind of expecting the answer to be no, but wanted to make sure, since any searches have turned up zero on the subject. I replaced my first replaceable wheel hub on our '12 Caprice. I wasn't even sure it was the problem, until I replaced it and the horrible grinding noise went away. All our other cars either have tapered wheel bearings, and I'm well-versed on those, or we haven't had problems with the hubs. We didn't track/autocross the Z28 enough to have any problems there.

So, can you/do you rebuild wheel hubs? It seems a shame to just throw out that big chunk of expensive paperweight, but if that's what's done now, so be it. Thanks.
