Ive had my 2000 expedition 5.4L for about a year and a half. I love it a lot and its taken good care of me. I cranked up the torsion bars and put 33 inch tires on it. I changed out the inner and outer tie rods and tightened the steering gear box. My tires are rubbing on the chassis so i wanted to put some 3 inch wheel spacers on it so that it wont rub when i turn. Now im getting death wobbles! Please help me figure out why im getting death wobbles at 40 mph so i can keep the spacers on there.
