VEHICLE DESCRIPTION: CLASS 8 HEAVY DUTY TRUCKS. THE AIR SUSPENSION CONTROL VALVE SUPPLY LINE WAS NOT PLUMBED THROUGH AN AIR PRESSURE PROTECTION VALVE. IN THE EVENT OF A FAILURE, THERE WOULD BE LOSS OF AIR PRESSURE IN THE 'B' SYSTEM AIR RESERVOIR THAT SUPPLIES AIR PRESSURE FOR THE FRONT STEER AXLE BRAKES.
Consequence & remedy
Consequence: THIS CONDITION WOULD RESULT IN INCREASED STOPPING DISTANCES.
Remedy: DEALERS WILL INSTALL THE NECESSARY AIR PRESSURE PROTECTION VALVE.
THE TRACTION SOLENOID EXHAUST CAN BE OBSTRUCTED DUE TO INADEQUATE DRAINAGE AND A BUILD-UP OF ROAD CONTAMINATION BETWEEN THE MOUNTING BRACKET AND THE SOLENOID HOUSING. THE OBSTRUCTED EXHAUST PREVENTS THE RELAY VALVE CONTROL AIR PRESSURE FROM VENTING AFTER A DIFFERENTIAL BRAKING TRACTION EVENT.
Consequence & remedy
Consequence: THIS CONDITION WOULD KEEP THE REAR AXLE SERVICE BRAKES APPLIED WITHOUT ANY BRAKE PEDAL MOVEMENT BY THE DRIVER INCREASING THE RISK OF A VEHICLE ACCIDENT.
Remedy: DEALERS WILL REMOVE THE SUSPECT VALVE AND INSTALL A NEW VALVE THAT HAS A MODIFIED SOLENOID HOUSING WHICH WILL ALLOW FOR SUFFICIENT DRAINAGE AND A NEW VALVE MOUNTING BRACKET WITH INCREASED HEIGHT TO REDUCE ENTRY OF CONTAMINATION.
THE REAR SUSPENSION AXLE RETENTION PLATE CAN BREAK UNDER NORMAL USE, AFFECTING AXLE ALIGNMENT.
Consequence & remedy
Consequence: THIS CONDITION COULD RESULT IN LOSS OF REAR AXLE STABILITY AFFECTING VEHICLE DIRECTIONAL CONTROL AND INCREASING THE POTENTIAL FOR A VEHICLE CRASH.
Remedy: DEALERS WILL REMOVE AND REPLACE THE AXLE RETENTION CLIP PLATES ON AFFECTED VEHICLES.
THE WRONG BALL SOCKET ASSEMBLY WAS USED TO ATTACH THE STEERING ARMS TO BOTH THE STEERING DRAG LINK AND THE STEERING RAM ASSIST CYLINDER, RESULTING IN A BINDING CONDITION.
Consequence & remedy
Consequence: THIS CONDITION CAN CAUSE THE BALL SOCKET TO FATIGUE, INCREASING THE POTENTIAL FOR LOSS OF STEERING CONTROL AND AN ACCIDENT.
Remedy: DEALERS WILL REPLACE THE BALL SOCKET ASSEMBLY ON THE AFFECTED VEHICLES.
