Good afternoon,

My 2017 honda crv ex awd 130k miles has a noise that sounds like it's coming from under/back of the car. I noticed it a few months ago and its still there. Sounds as if something spinning unevenly and thudding. I don't hear it at low speeds but once I hit 45 mph, I can start to hear the noise. Around 55 mph is when I can really hear it.

I checked both rear tires, all lug nuts are tight, tried to rock the wheel left/up down and spun them without any issues. If I were to guess, I think it's the drive shaft/ rear diff region? The youtube link I provided is the sound I am talking about when I am in my car going 55 mph.
