I have a 2018 Tradesman with the 5.7. Its also a 4x4. When the truck sets for a while,{ overnight, while at work,} it has a growling noise from the front of the truck. You can feel it in the pedals. Once the truck is moving, it quits making the noise and does'nt do it again untill it sets awhile.My first thought was sticking brake pads, but checking to see what you guys thought. Thanks
