2024 Silverado Trail Boss 5.3 w/ 5k miles
I have a rubbing/vibration in the driveline between ~20mph and ~42mph, sounds like a groan similar to driving over rumble strips, but it matches the shifts in the transmission. Determined it will go away when I engage the front differential, in Auto or 4H. Dealer is aware and acknowledged they can replicate, but was told they cannot find the issue and it’ll need to get worse to address. This isn’t a turn the radio up noise, once I hear/feel it, it ruins the drive.
