solenoid chatter

  1. Front Right Solenoid Chatter In 2wd

    Ford Raptor Performance Mods - 3.5L V6 EcoBoost
    2017 Raptor ...Front right wheel has had the 4WD solenoid replaced twice by two different dealerships, and now it's doing it again at highway speeds. Chatter stops when I engage 4WA or 4WD. Any one ELSE have this issue ?
