Good day.. Having a problem with vehicle mentioned above.. 2007 face-lift Mb W221 s600 with active body control (abc).. Vehicle developed a squeaky, cracking, clunky sound from left front side.. Took it to a local workshop, was advised it's lower control arm bushes had the entire lower control arm replaced.. Had the same problem after replacing was again advised to replace upper control arm which I did and to my surprise same sound still availed.. The technician then advised me it is the entire strut (shock) that's failed which I replaced reluctantly and sound is still there.. I went to another workshop after spending so much money my problem still persists, the workshop technician did some tests and advised to replace right hand side lower control arm, right hand side upper control arm which I did and again after replacing same sound.. I took vehicle back and was advised to replace right hand side strut mounting rubber it's wedged in between top side of strut.. I'm at wits end I've spent so much money fixing this.. Could you please send help..

Hello, any notable oil leaks getting on the suspension parts? Nobody seems to have mentioned sway bar bushings or links, or even subframe bushings. Does this noise appear only over bumps or in specific scenarios?

Some of these are difficult to replicate noises when on a lift. See if the shop has a drive-on rack where they can test with the vehicle's weight on the rack.
