MACK TRUCKS INC. HAS DETERMINED THE CAP NUT THAT RETAINS THE INTERAXLE DRIVESHAFT YOKE TO THE REAR AXLE INPUT SHAFT MAY BE SUBJECT TO PREMATURE LOOSENING ON CERTAIN CHU, CMH, CMM, CXU, GU, LEU, LR, MRU AND TD MODEL VEHICLES. THE POTENTIAL RISK IS THAT IF THE NUT COMES OFF, THE YOKE CAN SEPARATE FROM THE AXLE INPUT SHAFT AND CAUSE THE DRIVESHAFT TO DISCONNECT. IF THIS OCCURS, A DISCONNECTED DRIVESHAFT CAN DISABLE THE VEHICLE AND RESULT IN DEBRIS IN THE ROADWAY, WHICH INCREASES THE RISK OF A VEHICLE CRASH.
