How do I know if the wheel bearing hub assembly is bad

How many times are you going to ask this type of question. You have been informed, so now the best advice to you is to take it to a certified or qualified mechanic to hear the noise and tell you what it is. By the way it's a bearing assy. not a hub on a 94 maxima. I still have some family in Tulare, would you like me call them so they can drive to Fresno and tell you what it is!

You KNOW for sure if it was the bearing , if after replacement , the noise is gone. OR replace both front bearings and tires.
