I have a 2000 S500. It sometimes vibrates around 40 to 60 mph. The entire car vibrates. The back seat, the passengers seat and a bit throught the steering wheel. I have purchased new wheel and tires and I still have the same problem. It does not occur all the time and I cannot force it to happen. The first time it happened, I thought a wheel was coming off but all lugs were tight. Any ideas? Thanks.

Not yet. My next stop is to have the four wheel alighment performed by the dealer.

Depends where u are located, my dealer charges a lot for alignment and wheel balancing. Try using specialized independent shops that do alignment.

check the flexible discs of the propeller.

Thanks you for the suggestion. I am not totally familar with all of the technical terms so is this part of the drive train/rear end system?

you got two.
one that connects it to the transmission and the other one connects it to the rear differential.
check both of them.
there must be no play, tear, or enlarged mounting holes.

This really helps. I will take it to the dealer and update this forum on the status. Thank you very much. I was afraid that I would get caught up in chasing a symptom, making repairs that are not needed and still having the problem. At least this will help to focus on the most likely problem area.

Is there such a thing as the entire drive shaft needing to be replaced? And, under what circumstances would the drive shaft need to be replaced (other than the obviously, as with an accident of some sort)? The U-Joints of these drive shafts are sealed, are they not? I've noticed that they're not sold a lot, at least not for my vehicle. But the flexible disk...well... I never thought that would be a source of drive-line vibration! That is enlightening! And I thank you as well, because I've been having some vibration as well, and like this fella, I kept thinking it was wheels, tires, shocks, tie-rod ends, control arms, bushings, etc. Thanks

It's probably the wheel balancing.
I've had the exact same problem.
It turned out that the tire dealers I used screwed up. Take your car to Mercedes and make sure you have a professional look at the wheels.
I used two different dealers before taking it to Mercedes. Both screwed up and overweighted the wheels. All this despite having a brand new tire put on the car.
Poor Wheel alignment shouldn't make your car vibrate. Just pull in one direction or cause weird tire wear.
You may also have tar or something stuck to the propellor shaft. Check this.
Keep us updated on what the problem was.

Update: I decided to drive my S500 until I could repeat the vibration problem on demand. This decision was to prevent me from chasing the problem by spending money inappropriately. I have now driven the car an additional 3000 miles and the problem has not resurfaced. This is very strange. I will keep all of you up to date on my continued journey.
