Mikep123456 Posted February 22, 2021 Share Posted February 22, 2021 Anyone experience any type humming or harmonic type noise while cruising? I noticed it mostly when I’m on snow covered roads when it goes from drifted, unplowed to hard pack. Normally around the 4200 rpm range. As soon as the road returns to loose snow it will go away or if I drop the rpms. Sometimes I think it’s the tires humming but I switch off the 4 WD and it stops after it disengages. Not sure what it would sound like in sand or loose dirt at same speed or rpm’s. FWIW 2020 HD10 Limited Thanks Link to comment Share on other sites More sharing options...
