Maybe it’s the transfer case. Just throwing ideas out there. But that does sound pretty awful.
More stuff is eliminated than is left that it could bejust put a new clutch in, and its better, but still i feel somethings amiss
heres a video.

That's totally wild...I have no further input but I can certainly see why you're looking for answers. That's not subtle at all.just put a new clutch in, and its better, but still i feel somethings amiss

completely horrible, i hope the diff swap fixes this.That noise is totally F'ed up... I've only ever heard rollover noise idling or just off idle in 1st or second gear in my smf 7.3 zf5 and the noise mine makes is more of a grunt noise from the torque pulses going though the driveline. The noise in the video to me sounds like a trans that has popped out of gear and is grinding gears.
The noise is from the diesel engine hitting so hard when it fires, that it shakes the gears in the transmission. The zf being aluminum and using thin transmission fluid for fuel efficency makes it even worse. Ever wonder why the 460 never came with a DMF?I was always told rollover noise was an out of balanced engine. The DMF provided a buffer between the crankshaft and the transmission to mute the sound of the vibration being amplified in the transmission.
Did you build the motor? Did you have the crank balanced?
Right. If the rotating assembly is not balanced it will hit unevenly and cause rollover noise. Unbalanced injectors can also cause it. I have never tried to fix rollover noise by swapping motors, but i have changed injectors and improved the issue.The noise is from the diesel engine hitting so hard when it fires, that it shakes the gears in the transmission.
