Well, if it's not a grinding, clunking, or something else rhythmic, then it may not be your hub bearing. But if you want to check to make sure, jack up the side with the noise (use a jackstand). Once the tire is clear of the groung, grab on each side of the tire and shake. Check for play. Then grab it on the top and bottom and do the same. If it moves a lot up and down, look at the rear of the wheel and see if the movement is coming from the bearing. Hope that makes sense. If not, I'll try to explain better.

However, if it's a howling noise under your hood, you'd have to be more specific. I don't have a clue.
