I have recently purchased my dream car a 1968 cougar. But in my steering it is acting a little different. When driving down the road it grabs ruts really bad. I will be turning the steering wheel and before you know it will dive into the corner and when you go to counter steer you over correct. I was told to try and alignment 1st And if that does not work to replace the control valve. Has anyone ever ran across this and how did you correct it?
