VEHICLE WAS TOWING A TRAILER. WHEN THE LEFT REAR SHOCK MOUNT BROKE OFF THE AXLE. THE BRAKE LINE IS BOLTED TO THE SHOCK MOUNT. WHEN THE MOUNT BROKE, IT TOOK OUT THE BRAKE LINE, WATCH RESULTED IN THE LOSE OF BRAKES. AFTER HAVING A WELDER LOOK AT THE BRACKET WE CAME TO THE CONCLUSION THAT THE WELDS FROM THE FACTORY WERE TO COLD TO PENETRATE THE BRACKET OR THE AXLE. WE PUT NEW BRAKE LINE ON AND REMOUNTED THE SHOCK BRACKET TO AXLE. WE REROUTED THE BRAKE LINE SO IT WAS NOT ON THE SHOCK MOUNT.

WHILE DRIVING 65 MPH VEHICLE STALLED. VEHICLE WAS TOWED TO THE DEALER FOR INSPECTION, AND MECHANIC DETERMINED THAT FUEL PUMP, COMPUTER SENSOR, AND FUEL LINE NEEDED TO BE REPLACED ,AND REPLACED THEM. HOWEVER, THE PROBLEM RECURRED. *AK
