On my CL600 (2004, W215) there is a rapid high-pitched pulsing at any speeds over 40 mph. Any idea what could be causing this?

Hello, welcome. My name is Mike, I will do my very best to
assist you with your question.

Can you tell what area of the vehicle the sound is coming from?Front,rear,etc?

Customer: replied 4 years ago.

Thank you Mike. The sound is coming from the front and I would guess from the drivetrain.

What normally causes this issue is the coupling bearing on the driveshaft which is common to fail and requires replacement of the driveshaft I am also a warranty inspector and have inspected this issue many times on these vehicles.
