I feel a gentle sway in the steering of a '93 240. It is most obvious at a little under 30 MPH on coast; it is so slight and slow that I cannot call it a shimmy, but it still definitely is there.

Perhaps unrelated, this follows a violent shimmy the car had at highway speeds which occurred VERY intermittently. That bit of head scratching resulted in removing the driveshaft to check the u-joints and flex joint, then installing new ball joints, new tie rod ends and new front end rubber. I finally thought I found an explanation when a front caliper showed to be a bit hinky. So, it seemed to be a good time to renew the brakes (calipers, pads and rotors) at all four corners.

Since the suspension/brake work, the highway speed shimmy has never reappeared, still the mild, slow speed sway persists.

One thing I have noticed, again it could be unrelated, is that the ABS on this car is much quicker to act than on my others. I did inspect and clean the reluctors and sensors when the brake work was done.

I'm uncertain where to go next with this problem - perhaps delve into the unknowns of the ABS. Does anyone have any suggestions or similar experiences?

Thanks, one and all.
