Well I awhile ago I got my 1995 Mark VIII in the mood, like buried down to the undercarage and after two towing companys couldnt get it out i finally got it out. Ever since then it has been shaking as soon as I get up to 60 and gets worse as i go up from there. I have studded snow tires on it but I dont think it shook before I got it stuck... Any ideas what it could be?
