I cant locate the thread that was on here recently about the quality of aftermarket wheel bearings....seems to me there was some doubt about the quality of bearings offered by the big 3. Is it better to go to a bearing supply house and get them cross referenced? Also ...when a used bearing has been cleaned with solvent and spun to check for wear:if it spins smoothly it should still be good, right?...if it runs rough its no good. Should it be silent when spun other than the normal metallic noise they make? Karl
