I had a "clunk" as well so I replaced the front DS wheel hub assy about 3 months ago and am now starting to run into the same problem. There's more symptoms. Car pulls a little to the left, theres a metal scraping sound (kinda like the break pads are worn, but they're not) when turning left, and occasionally when breaking I feel/hear a metalic grinding sound. I hate to think the wheel hub is bad again, but I heard that it is not uncommon to get a bad one.

Does anyone know if there is something I'm missing? Could there be something else causing the wheel bearing to go bad?
