Hello,
I saw in one of your posts regarding your ML550 you had a clunk when turning. I too am having that from my ML550 drivers side when turning left. The dealer seems stumped and I get the “couldn’t duplicate”. For me its a repeated clunk-clunk-clunk as the wheel is turned and I’m proceeding through the turn of the car.

If you have your service paperwork for that diagnosis, I would love to pass it on to them. No need to send the full thing with your personal information, just that page, section would be a huge help.
