    E-450 with V10 serpentine belt instability and noise

    We have a 2017 V10 powered RV, Fleetwood Jamboree 31U. Love the RV but the belt noise has been driving us crazy. The sweet spot in RPM is about 2100 up to 2500 and of course, 2100 is where the noise starts including every upshift to get to cruising speed. We put the idler wheel on and just like magic, the noise is completely gone! After several years of listening to that crap, I still anticipate hearing it but it is just psychosomatic it doesn't exist in the real world anymore LOL. If you are having these issues with noise driving you batty, put the idler wheel on and enjoy your new found peace and quiet. Have a great day!
