It is under the car connected to the steering components. You will see it because it looks just like a shock, which it is. When worn, they allow slack in the steering, which could cause sway. Most times when you disconnect this shock, damper on these older cars, there will no shock action at all. I mean absolutely no bounce back or resistance, which in my experience causes more of a shimmy action moreso than a swaying action.
