Update: jacked it up and checked all 4 wheel bearings looks good to me but driver’s rear is noisy when I turned it. I am thinking rear drum since the parking brake was sticky after I parked it but that is often the case on rainy days but it usually just pops off when I roll. Maybe it left something behind.
It is not linked to engine rev but is linked to road speed. Turning the wheel doesn’t change the sound. Sound is the same driving on tar or dirt. Sound goes away under 20mph.
