front wheel bearings?
Last year I've noticed that the front wheel bearings on my '93 Z28 are horribly loose. So OK, I've got new hubs from Autozone and replaced them. Now less than a year later they're horribly loose again. I autocross the car, and the alignment is pretty aggressive, but overall I don't drive the car that much.
This makes me wonder, are the Autozone hubs crap? Or will it be the same with the original Chevy parts too? The Chevy parts are at about $300 each online, while Autozone is only about $100.

Did you try tightening them with channel locks the first time, or you just bought new ones?

Timkin is $130, Duralast is $99.
Timkin has a 3 year warranty, Duralast has a 1 year...

Just bought the new ones. They are sealed hubs.
For what it's worth, Summitracing has some Auto Extra hubs at $75 apiece, claiming to meet or exceed the original part performance. GM seems to be getting low on these parts in storage, since the hubs for the new Camaros are much cheaper than for the old ones.

I don't remember which bearings the AutoZone brand uses but I've installed a few, in daily driver cars not used for auto cross. I did have one come back not too long ago for the same hub. Rock Auto has hubs for a 93 listed from $54 - $171. I would personally go with the Timken hub part number 513090 listed for 118.99. I've installed a few Timken units and the only difference I could see from the OEM part was the lug studs.

I think there was only one brand at their web site. Probably Duralast, at least I think I've seen this name. They looked exactly the same as the previous ones minus rust (I think the previous ones were from some place like NAPA, not original either).

Can not say that they lasted a whole lot longer. Well, they did, but they've got to a much worse condition before I've noticed it and changed them. The funny part, with the negative camber, the freeplay can be felt only when a wheel is lifted in the air, not on a standing car.

you expect to feel bearing play on a car sitting on its tires? maybe i'm misunderstanding this.
are you running a lot more negative camber than stock?
I know the vette guys replace the stock bearings with a beefy and expensive aftermarket set but I cannot remember the name right now. and i don;t know if they have 4th gen ones.

Yes, usually when you pull and push the top of the wheel you can feel the free play in a worn bearing.
I run as much negative camber as it would go with stock adjustment range. Almost 1 degree. And since I autocross it in the stock class, the bearings have to be of the factory type

Sorry, do you have one or two of them? Well, I guess with the time it would take to send the check and get the bearings shipped back, and with people saying that all the bearings are about the same, probably easier to order from Summit anyway.

AutoZone hubs are also "made to meet or exceed OE spec" and they give you a little graph to show all the meeting and exceeding.
You are putting the bearings though one of the hardest tests a bearing can be put through. I would do the warranty dance every year and get new ones since at this time AutoZone does not care how many times you warranty it. If you want to spend 2x the money and get an extra season out of it, you could do that too. I've noticed no increase in warranty bearings between the AZ brand and the Timken brand we sold, they were about the same.
