I listened to your video but can't identify the noise.

Of the 4 wheel bearings I've had go bad only one had any play in the wheel. Our bearings will make awful noise when they're going bad but have 0 play at the wheel.

 

The noise has changed from that chirping noise in the vid to a quiet kinda grinding noise, and now it's mostly gone away. I've had a busy week and haven't had time to check the diff fluid for any metal at the APG Auto Crafts Center. When I can I will do that to make sure the noise isn't coming from there.

I jacked up the rear end of the car and tested the right rear wheel (and the left, just in case) for noise or play, but there wasn't any. I do think that I'll get the wheel bearing replaced anyway though. Thanks again for your input everyone

 

Wheel bearing has been replaced, noise is gone. Thanks again guys. I really don't know why 2 other shops said nothing was wrong with it. The shop that fixed it said it had damaged the hub as well, so I also had that replaced and got an alignment. All 3 of those only set me back ~$400. Not bad.

 

When my wheel bearing was bad, it did the same thing. After driving for about 15-20 minutes, it would make the noise. I changed out the diff and it still made the noise. Thought was the brakes, so we checked it for clearances. Finally someone told me to check the wheel bearing and that was the culprit.
