what's causing my car to rattle and shake?
my car shakes slightly when driving. feels like i'm driving while the wheels are not tightened on. when i'm braking, i notice it shakes some along with a rattling noise. when i'm driving 25-30 mph, i feel like i have a bump in a wheel. you ever seen a bike wreck and the kid goes home with his bike tires bent up. that's what it feels like. when i'm going 70-75mph, it shakes violently, but no noise. i have new rotors and brake pads. don't need brakes. what's going on?!
