Yeah I heard the noise this weekend. Odd to say the least. It's only on light load, tip in of the throttle in 5th. Which, because of the wide flat torque curve of the 8.1 could happen at 30 mph or higher. The faster it's going the worse it sounds though. Similar to putting a few golf balls in a blender and hitting Frappe. A little more muted, but rough none the less.

Normally I've got a higher tolerance for noises than Larry does (or higher amount of hearing loss), but at highway speeds it's downright obnoxious. The only way to make it stop is to completely let off the throttle or keep your foot in it. Driving either way would be annoying. Anything that makes that vibration along with the noise can't be good for itself long term.
