e320 Steering Wheel Shimmy

Hello,
This is my first post although I have enjoyed the technical advice for some time. I have a '97 e320 with under 90,000 miles and new Michelin MVX4 Plus XSE tires (which were also the brand installed when I
purchased the car). Lately, I have noticed a constant jiggle (vibration) in the steering wheel. At first, I attributed it to the rutted-out interstate pavement; however, I notice it at various speeds on various roads. When I let go of the steering, the car does not pull to the left or the right, but stays straight on, so I think the wheels are aligned properly. Can anyone provide possible causes? I always like to approach the dealer with some foreknowledge!
Thanks,
Ian

Have the tires balanced by an alignment shop, not a dealer.
A '97 model, unless under Starmark warranty, should be taken to an independent MB shop - but it's your money.

First get the tires balanced on a high speed spin balancer or a similar type of computerized machine. That should take care of the vibration.
Second get a four wheel alignment by a good front end specialist that is familiar with MB. I live in a town of 80k and I trust one guy to do it right, He does my Vette too.
If you still have a shake it probably is the tie rod ends. They usually last about 60k miles. My dealer told me that tie rod ends are the most common suspension part that go out in that model. My 96 has 70k miles and I just replaced the tires with the exact same Michelins and it drives smooth as it did when it was new. There is no reason why your car shouldn't drive smooth as glass again also.
