Last night is was turning into a gas station and noticed a Loud Clunking noise comming from the rear end of the car. Then every 3 feet or so the noise would happen again whial i was going into the gas station and when the noise happens my whole rear end jerks very harshly. So i got my car towed back to my house because it was un-drivable i thought. So whial i was pulling the car into my garage getting it off the tow truck the Tow turck driver said my tires in the rear were moving and swaying left and right like they were going to fall off and still the noise kept comming. The i Checked the lugs and they are torqued on correctly and everything seems to be allright when i look at it. Does anyone know whats wrong?
