What kind of noise is yours making? I get a whinning from the rear of the car that changes pitch with speed. It does not go away or come back in with accels or decels. I've also noticed that when I am in a right hand turn, the noise goes away.
I am thinking that it is the right bearing beacause it is unloaded during these turns. I don't want to change the wrong one as it will take some time to do and the bearing is expensive. I paid $78 just for the one.
Your hub should be fine. Just change the bearing. Mine has been doing this for 15-20k miles.
