Hey all,
I started getting a loud noise rubbing/humming when I hit about 30 or 40 from the left rear last week

. I think I have traced it down to the wheel bearing. I jacked up the car and the left rear tire has alot of wiggle room back and forth when I try to move it, unlike the right rear. The noise also disappears when I turn, I think relieving the pressure on the bearing?
So my questions....Do this sound like the correct diagnosis?
Can I replace only one wheel bearing? or should I replace both rear bearings?
Anyone have any advice on where to get the parts from? My plan is just Autozone or Advanced auto parts or something right now
Thanks! Nick
