When I drive the car there is a strong rhythmic and regular noise, and vibration from
the left front side, a noise that sounds like it comes from something rotating. I've
checked the wheel and it looks ok, no wheel bearing play or noise. On the left drive
axle there is a round rubber donut looking device called a dynamic damper...same on the
right drive axle. The right one is very solid and inflexible with no obvious cracks.
The left side one is soft, very flexible, and has some good cracks.

Is it possible that an old dynamic damper can cause noise and vibration as I described?
The noise is worse at lower speeds when I take my foot off the pedal and is enough of a
noise/vibration that it doesn't feel like I should be driving the car very far.

Anyone care to express an opinion?
