THE RIGHT REAR PASSENGER WHEEL CAME OFF MY 2004 FORD EXPLORER WHEN I WAS DRIVING WESTBOUND ON INTERSTATE 70 NEAR KINGDOM CITY, MO. ALL FIVE (5) BOLTS AND LUG NUTS SECURING THE WHEEL/TIRE WERE BROKEN OFF. MY WIFE AND I WERE TRAVELING AT 70 MPH IN THE RIGHT HAND LANE OF INTERSTATE WHEN THERE WAS A SUDDEN LOUD NOISE FROM THE REAR AND THE VEHICLE SWERVED VIOLENTLY TO THE RIGHT AND THEN LEFT. THE VEHICLE SPUN AND ENTERED INTO THE GRASS MEDIAN IN THE MIDDLE OF THE INTERSTATE AND THE CABLE STOPPING SYSTEM. THE VEHICLE BECAME ENTWINED WITH THE CABLE SYSTEM CAUSING IT TO FLIP ON ITS SIDE AND COME TO REST. THE LEFT AND RIGHT SIDE AIR BAGS DEPLOYED, BUT THE FRONT AIR BAGS DID NOT. MY WIFE AND I HAD DIFFICULTY RELEASING THE SEAT BELTS SINCE THE VEHICLE WAS LAYING ON ITS RIGHT SIDE. I WAS FINALLY ABLE TO RELEASE BOTH SEAT BELTS AND OPEN THE SUN ROOF FOR BOTH OF US TO EXIT THE VEHICLE. THE ENGINE AREA WAS SMOKING, BUT DID NOT CATCH FIRE. LUCKILY, MY 2004 FORD EXPLORER DID NOT COMPLETELY ROLL OVER OR THAT MY VEHICLE NOR MY LOOSE REAR WHEEL AND TIRE DID NOT HIT ANOTHER VEHICLE THAT WERE NEAR ME ON INTERSTATE 70 AT THE TIME OF THIS ACCIDENT. UPON EXAMINATION OF RIGHT REAR WHEEL WELL, THE RIGHT REAR WHEEL AND TIRE WERE COMPLETELY MISSING AND THE FIVE (5) LUG BOLTS HAD ALL SHEARED. THERE APPEARED TO QUITE A BIT OF FLUID AROUND THE WHEEL WELL. IT MIGHT HAVE BEEN BRAKE FLUID. WE WERE ABLE TO FIND ONE OF THE LUG NUTS, WHICH STILL HAD A PART OF THE SHEARED BOLT REMAINING INSI
