Hi Derek,
It goes well, thanks.
I can't be sure just based upon which way you are turning. However I believe that if you jack up each rear wheel and rotate the wheel that the side with a bad bearing will make a louder sound than the side that is o.k. The bearing is roughened and so even though it isn't being spun at 55 mph and having the stress of turning put upon it I believe the roughness will be audible to you if you listen carefully. Other than that approach, I'd guess at the right side but that is just a hunch. You might also get a friend to sit in the middle of the back seat while you are on the road and see if he can determine which side the sound is coming from.

i hear it in the front of the car and i think the right makes a louder sound when i spin it and i have the back hubs off and they seem to be fine and i lub it back up before i put them back on so i think it might be the back

Answer
Hey Derek,
If you still think its the right rear, then just buy the bearings and a seal and do that side. You should be able to inspect the bearing and race and detect that it is bad that way. In my experience though with rear wheel drive cars when the fronts were just like the ones on our rear wheels of our front drive cars, you could feel a  bad bearing's roughness when you rotated the hub by hand as a subtle  vibration. If not, then all you can do is remove the one you suspect and inspect it and its race for signs of damage.
Sorry I can't give you the magic answer. But get someone to help you listen who is sitting midway in the back seat and if their hearing is balanced they should be able to tell you which side is making the noise.
