So I ordered a Timken wheel bearing from Amazon. Wasn't available at the local O'riley, Autozone, or Advanced (all 3 sold a National bearing with the same part number). When it arrived, it looked fine, but I noticed it had Koyo stamped on the bearing.
Is this a problem? I've heard the Koyo is the OEM bearing that came with the factory car. So, if I got it for the price of an aftermarket brand, maybe it's a good thing.
