Hey folks, I will include an imgur link at the bottom for the video with sound since i cant figure out where to attach it. I've got a 2020 Suburban Premier with 100k miles thats making an awful roaring noise that sounds like mud tires. I replaced my tires with Michelin Defenders today and it made 0% difference in the sound.

It is so loud now that we actually have to speak up quite a bit just to talk in the car. I thought maybe its a wheel bearing but no amount of swerving or rocking the wheels while its jacked up gives me any indication of a bearing failure, but its quite possible. Im thinking either rear bearing or differential. But letting off the gas makes bo difference.

It sounds like its coming from everywhere inside the car but if I had to pick a corner, I would say right rear. Let me know what you think or if you've had this problem. Thanks!

Welcome to the Forum from NH.

Lots of knowledgeable folks here who freely share their knowledge, experiences, and perspectives. Knowledge is power.

I hope that you will become a participating member in the Forum's discussions.

Pics of the truck, please.

I recommend that you take the truck to a trusted local repair shop, and get the truck on a lift with the wheels off the ground and with someone inside the truck. Put the truck in gear and press the gas pedal a bit, and see if the noise also occurs in the unloaded situation (wheels off the ground). If the noise still occurs, then the Mechanic underneath the truck can go around, with a stethoscope if necessary, and locate the source of the noise. From what you describe, a stethoscope probably won't be necessary.

I've had a wheel bearing sound like that when it failed. Any leakage around the right rear brake backing plate?
