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.

On my 2001 TA, I had one of the first sets of XTracker hub adapters, after trying a set of "rebuildable" hubs that both unfortuneately failed, 1 on track, 1 on autocross. The rebuildable ones had metallurgy issues that the guy making them could not ensure against. The XTracker plus bracket on my TA have been flawless. It seems sad to have to replace a big chunk of metal, but it's where we are with cars I guess.

And we all know, every car has its engineering compromises. My wife's Honda can't replace a front wheel stud without taking apart the hub and rebuilding/repacking it. Strange but true.

Sad, but good to know. Yeah, the 'compromises' sometimes seem to be the manufacturer/vendor just getting cheap, but that's another story. My. one volume 1968 Cadillac FSM has steps to rebuild parts, like alternators (they still called them 'generators'), starters, distributors, etc., yet my 8 volume 2018 FSM for our Tahoe PPV (around 40 pounds of books) has 'test unit, if test fails, replace unit'. Coming from that space, I find it hard to just pitch a big lump of metal in the trash.

I guess I'll go ahead and let it keep the landfill from floating away....
