I understand this is an age old question, where is the noise coming from. Brand new Dually, less then 100 miles. At around 50-55 MPH i hear a light whistle from the driver side. as i get up to 72 it is constant and very noticeable. Below 50 and you can not hear it. iv tapped everything except the grill and hood at this point. and the noise still persists. I know the 2020s had a hood seal issue, not sure if this would be a issue still since they issued a bulletin last march. Took it to the dealer and they helped as much as they could since i did not have a appointment. i have one schedule for 2 weeks but if i can fix this myself i will. I am not sure if it would be a mechanical issues? the sound seams to be coming from the left side near the oh ****** handle. but i took that off and blew air and tried finding a hole and tapping it and nothing. If anyone has any other recommendation i would greatly appreciate it.
