Wheel bearings are a decades-long weak point for GM. Every parts store worker I've talked to says they sell GM bearings 10 to 1 over every other brand combined. On a couple of my late 90's GM cars, I replaced so many of them that I almost came to consider them a maintenance item. If I used an OEM bearing or an economy brand aftermarket, or even Raybestos brand, I'd just be doing the job again in 20-30k miles. The only bearings I found that held up any better were if I installed Timken bearings.
