2000 Blazer front wheel brg hubs

BlazerLT, If I could get someone or the parts house to give me a part number for the bearing I would be willing to try to just replace it. But they don't even list the hub assembly nor the bearing. They show a hub assembly for the 4X4 but not the 2wd. It's weird, and the GM dealer loves it! Not even tring to help! I saw in a later thread were someone stated they got hub assemblies at PEP BOYS, I called the one in Bossier City, LA today and they didn't list it either. I know someone else in the world has got to have run into this problem,
