My car has the same issue even though my tires are fairly new and balanced, but I'm kind of reluctant to do something about it because it seems like a big job, I don't have the proper tools and it doesn't bother me very much or most of the time. Is an alignment required after this job? I'd hate to have to do that again because the local MB dealer had trouble getting it right last time. I noticed that the road surface also affects the extent of the shimmy. On rougher roads it's a lot less noticable. But on a very smooth road, on a hot summer day and around 55 mph, the shimming is embarrassingly noticeable.
