I get some cracking noise in the back, sounds like coming from the trunk but i checked and removed everything from the trunk and it is still there, it only happens when driving over big bumps on the road.

WELL SAID AND PROPER WAY TO RECTIFY.

I was having the same problem took it to the dealer today and they told me I needed a sway bar, tie rods, engine mounts and I have an oil leak. I'm glad I took that 2 years extra cpo coverage.

Mercedes S Class S320 CDI (W221)
My S Class (W221, S320CDI, 2006) does also have this suspension noise problem, but worst on cold startups, and always on road bumps. Very irritating when driving a car like this. I get noise both from front and rear suspension. My MB-dealer is not capable of locating the couse of the problem.
From having read this tread, can I conclude with replacing the front suspension sway bar is the fix? What about the rear axle? Is there a similar sway bar to replace?

I see. So these are the sway bar bushings aren't they? Any tips on how to remove it? A step by step would be greatly appreciated. Also what kind of glue/epoxy is being used?

I'm getting a rattle at low speeds going over the smallest imperfections in the road. I'm thinking its from something to do with the suspension (possibly torsion bar from what i've been reading). Don't really hear it over bigger bumps or at higher speeds. Is this what your problems were like??

How does one remove the sway bar? What all needs to come out before I get to the sway bar?

I realize you responded to this some time back, but I was hoping that if you still have the service bulletin would you email it to me @ hkeith985@icloud.com
