Sudden rattelig/klunking
Hi, guys, was enjoying my amg today, going around 120-140km/h down the highway. Suddenly it sounds like the fan to the backseats started making an odd noice. I stopped at the gasstation to turn everything off, but as i was braking it disapeard. Around 20 km/H.
at lower speeds it sounded more like klunking and flapping. I checked my undertray and wheel arches - all good. I also tried pulling the drive shaft to listen for looseness - nothing odd there.
After I continue and test it at speed.
gears are working good, no vibrations or abnormalities while driving, only this weird noice.
When accelerating it is almost like everything tightens up and it dosapears until i let off the accelerator. Most noticable between 20kmh to 10-120. At higher speeds it is there, but nothing too dramatic.
The noice seem to be in/under the midconsole between the seats and also on the right behind the glove compartment.
Video attached at about 120km/h

EDIT: one more at 40-60kmh

It kind of sounds like the driveshaft center support bearing has gone out. Or another possibility could be the driveshaft flex disc’s are broken. It definitely sounds like it’s coming from the driveline

Surprised it was the bearing and not the rubber bushing as it created a lot of noice, but apparently the bearing is fully capable to make these noices by itself. Even with a healthy rubber bushing.
for others that might run into it.
