THE DRIVESHAFT TO THE FRONT DRIVING AXLE IS SECURED TO A BRACKET USING TWO PILLOW BLOCKS. THESE BLOCKS ARE OF INSUFFICIENT STRENGTH TO SUPPORT THE DRIVESHAFT AND COULD FAIL.
PILLOW BLOCK FAILURE ALLOWS THE DRIVELINE "JACKSHAFT"TO DROP DOWN ONTO THE ROADWAY AND CREATE A SAFETY HAZARD TO OTHER VEHICLES.
MACK WILL INSTALL THICKER PILLOW BLOCKS AND SUPPORT U-BOLTS.
