Can someone help me figure out this sound? I have a 2021 Silverado Custom Trail Boss with the 4.3L V6. Around 85k miles. The truck runs great and there are no check engine lights on. The MyChevy app diagnostics say everything is running fine.

I can’t hear the noise from inside the truck, only from underneath or near the wheel wells.

I’d really appreciate any advice or ideas. Thanks!
