Default Diff or wheel bearing? Guess this noise!

Something is about to explode in my car. I'd like to pinpoint the problem so I can begin to research parts & options.

Video of the noise:

1. It is rhythmic and frequency increases with speed.

2. It is only audible when going +20mph.

I though it was my rear diff at first because a while ago I found a piece of a small gear on the magnetic drain valve, but after some searching I do not know if it's the diff or wheel bearing.

Please take a guess - any direction is appreciated.

Thank you!
Eric

I was able to take some turn on some on/off ramps earlier today and realized it get quieter when I take a left and louder when I take a right.

Is it safe to assume that the left wheel bearing is going bad?

I should just get these done as a set though, correct me if I'm wrong.

Thanks!

Ya, as you turn it creates pressure in different spot on the actual bearing. I had this problem with my 92 Integra. The noise will get louder as you drive it. Well no you don't have to change them in sets/pairs but you should have them all checked by a reputable shop to make sure the others are ok and not wearing out. Another way to check is jack up the suspected tire with the noise and spin it by hand and listen for a kind of grinding noise in the hub/center of the wheel. If you hear it then jack up another one and do the same. That should eliminate the possibility of it being road/tire noise from the ground.

Just got her fixed up today, it was the passenger side wheel bearing. Since I drove on it for a few weeks it did some damage to the hub so that had to be replaced as well.
They had some trouble with a bolt and replaced some bearings so it ended up being over $600 but it's very worth it to have a peaceful ride now. Thanks PrezaDriver!
