I have a slight shimmy at speeds 45-55 on some roads.

But more importanly, I also have a fairly slight play in my steering, that when I am taking a slight curve at highway speeds , if I correct it will sometimes overcompensate and I have to correct again in opposite direction.

Someone mentioned tightening a steering box on another model car in another thread. Could this cause play in steering and can I tighten it in a 93 400 SEL?

One benz tech said there is nothing wrong with it , but I know my car and he did not drive it under all conditions to feel it like I did , I am going to ask for a second opinion, but would like to know beforehand what to look for with him when he checks it

Am i imagining it , or does it happen to my year car
