Newbie - 07 E350 4Matic - Very Hard Suspension and Ride???
Regarding mounts, they may or may not be faulty, but it has nothing to do with stiff ride and OP's question.
I wouldn't be surprised if shock absorbers where replaced with even sportier ones without any written trail in order to avoid warranty issues.
One thing is certain: No German car will ever ride like Cadillac or Lexus. For better or worst.
OP seems comfortable tackling all the suspension work he wants to try himself. So if nothing else he'll get some good experience on his new car. There's nothing wrong with that.



Absorbers last for 300,000+ miles-you know just as well as i do he was referring to shocks. So reading the post carefully or not is irrelevant-he always has some witty response to something someone has said..... like talking about a vehicle that has 300k miles on it-bye felicia

By the way, I just sold Audi A8L and I know few guys with 300K miles and original air struts (all four are struts). Schock absorbers are extremely well made. They can do that if they want. OE replacement strut is $1800




I sold 2 MB last spring both with 266k miles each .
Our W211 wagon will have 160k next week with front factory struts (yes I have records)
You don't know much about the brand and you are making statements about it.
MB is not strange to design hick-ups but this is rare exception not the rule.
W211 is strange animal in the fleet with air suspension and SBC, but in this case we are talking about struts.
What guy messing up airbags can know about them?

You have a M272 engine-i'm willing to bet if they haven't been replaced already, the engine mounts are shot. Especially at 120k miles....
I checked all service records and it appears that the engine/trans/transfer case mounts have not been replaced. Thanks for all of the input from everyone; appreciate learning all that I can about this model. Given that I have never owned an MB, I don't know much about the "M272 engine". All I know is that it is a 3.5L DOHC SFI 24-valve, 6 cylinder. Yet don't know much about performance, durability, etc. Sounds like my first task will be to check all mounts.
More and more i start to feel that my car need new strut, but my indy shop say there is nothing wrong with the strut.
Thanks,
