Looking for any help pinning down what this is. I’ve left it at three different dealers for a total of a month this year and none are able to “replicate” the sound despite my demonstrating it for them when I drop off the truck. Some facts- rarely makes noise during winter only in the summer months. It went away for an entire month then came back. Is related to when the car rocks from side to side like going from a driveway to road over the curb or as in the video driving over a two inch lip at under 10 mph. It sounds like it’s coming from the dash but when I turn off the vehicle and stand on the running boards and rock it I hear the sound coming from what seems like the frame under drivers side middle row. It drives me absolutely crazy and I just want it to go away!!
