2009 ML550 mechanical issue when accelerating
I have an issue with my 2009 ML550 that i know will require a trip to the shop, but I would like to be equipped with information and something resembling a clue before I head there.
Once in a while when I accelerate after coasting, i will hear and feel a "clank" that is coming from what I would make a baldass guess is coming from the connection from the driveshaft to the rear differential. It's definitely somewhere behind the driver and it's a clearly mechanical noise accompanied by a slight "thump". It only happens when I accelerate after coasting. Once in a very long while it happens when I accelerate from a full stop.
What might be some of the more likely reasons for this? I know this is not enough for a diagnostic. I just don't want to go in there to get bull****ted by some German mechanic.
(Unfortunately, my Bull****-o-Meter(tm) does not understand German...)

2009 ML550 mechanical issue when accelerating
I had a similar problem on my 2010 550ML and had to have the transmission mount replaced when still under warranty. The noise was also evident upon flooring the gas pedal from dead start.
The new tranny mount fixed the problem.
