I replaced mine, same side rear on my 04, I didn't notice the sound and it probably was bad for a couple years until a car repair friend was sitting in my back seat and told me my bearing was bad! It looked like it was an easy replacement until I found the hub was frozen and took me a couple hours to get it off! I think I paid about $65 for the hub at a local auto parts store, you probably might get a better price on line...If you have to take your drum brake shoes apart, remember or take a picture of how they came off cause sometime you can't find where that extra part/spring goes..Just a tip, good luck
