IF THE VEHICLE IS OPERATED IN THIS CONDITION, ONE OR MORE OF THE FOUR BOLTS COULD COME LOOSE, CAUSING AN ABNORMAL NOISE FROM THE REAR AXLE AREA. IN THE EVENT THAT ALL FOUR BOLTS LOOSEN COMPLETELY, SEPARATION OF THE REAR BRAKE AND HUB ASSEMBLY FROM THE REAR AXLE CARRIER COULD OCCUR, WHICH COULD LEAD TO A LOSS OF VEHICLE CONTROL.
Toyota is recalling 2003 Corolla models with VIN numbers starting with 1NX. The bolts that join the rear brake and hub assembly to the rear axle carrier may become loose due to insufficient tightening during the assembly process. Noise or compete separation of the rear brake and hub assembly from the rear axle carrier could occur, leading to a loss of vehicle control. Dealers will properly tighten the bolts.
