'03 W211 E55 driveshaft area rattle, only over 35mph
Video while car is on a lift:
Noise happens both while driving on the road or with the car not moving, on a lift, with wheels spinning in the air in D or R.
Noise still happens while driving in Neutral over 35mph.
Rattle seems to come from the driveshaft area in the middle area under the the car.
No loss of power or any unusual drive train issues that I can tell. Just the rattling noise.
Sounds as if something is physically hitting the metal heat shields somewhere above the exhaust pipes.
Any ideas on what might be causing this rattling noise?
Thank you.
