93 5.0 5spd. Stock execpt for headers and exhaust. Not sure if this has been covered but I'm new here. I live in S Fl and every place i go no one can solve this problem.I have a real bad vibration at 60mph.It feels as if the steering wheel is going to shake off in my hand. When I accelerate past 60 the car shakes more violently. When I let off the gas the car is still vibrating. When I'm in my driveway and the car is out of gear I can rev the crap out of it and no vibration. I have replaced the tires and the same prob. I had these tires balanced like 5 times. I replaced u joints, shocks, struts, wheel bearings, rotors, inner outer tie rods and no luck. Don't know where else to look. I'm tired of spending money......Please help!!!
