I marked the relative position of the two lengths of driveshaft and then loosened the coupler with a 46mm wrench and a large adjustable wrench.



There is a circlip that must be removed and then a shield.


The center support rubber was cracking.


I tracked down a new genuine Mercedes center support (part number 123 410 10 81, made by GMT), which wasn't easy because they are apparently no longer available. But, ECS Tuning was able to get one in after a couple of weeks. It was ten times as expensive as aftermarket, but all the brands I could find seemed to be made in Taiwan, China, Thailand, or India and I don't want to be replacing the part again anytime soon.
