Bad Hub or Wheel Bearing?

[joshua6060]

How do you tell the difference between a bad rear wheel bearing and a bad rear hub? Also, how can I determine which side?

This evening I jacked the car up and tried to shake the wheels and neither would move......

I have been hearing the medium level "roar" a little while now, I assumed it was because of the balding Kuhmo's I had on the car but when I picked the car up from the tire shop, my tire guy said that when he test drove the car he hear the noise and he thinks its a bad wheel bearing (possibly driver side but he couldn't really determine which side it was) He then said it might be a bad rear hub.

Now that I have new brake pads, new tires, fresh oil, and a new battery, i'm ready to get this wheel bearing/hub taken care of so that I can enjoy the spring top down season.......
