I WAS HEADING NORTH ON THE HIGHWAY AND I CHANGED LANES FROM THE LEFT TO THE RIGHT LANE. ONCE I CHANGED LANES MY CAR JERKED VICIOUSLY BACK TO THE LEFT I CORRECTED THE PROBLEM AND WENT BACK TO THE RIGHT, BUT THE CAR RAN OFF THE ROAD AND LOST THE REAR PASSENGER WHEEL AND TIRE. THE TIRE WAS STILL INTACT WITH THE HUB AND AXLE (LUG NUTS WERE STILL CONNECTED ALL OF THEM WERE TIGHT.) THIS SHOULDN'T HAVE HAPPENED. I BELIEVE I WRECKED BECAUSE MY REAR AXLE BROKE. AND FURTHER MORE MY AIR BAGS MUST HAVE BEEN DEFECTIVE BECAUSE THEY DID NOT DEPLOY ON IMPACT. THEY HAD DEPLOYED WHEN THE TOW TRUCKS BROUGHT THE CAR OUT OF THE HOLE. *NM
