1967 Mack R Recall

VEHICLES EQUIPPED WITH FE970 FRONT AXLES AND WHEEL DISCS AND ROCKWELL INTERNATIONAL MALLEABLE STEEL FRONT AXLE WHEEL HUBS. A DESIGN DEFICIENCY EXISTS IN THE ROCKWELL MALLEABLE IRON WHEEL HUBS (CASTING NO. 333-V1-36) THAT COULD CAUSE THE WHEEL MOUNTING FLANGE TO CRACK AND FAIL WITHOUT WARNING. A HUB FAILURE WOULD ALLOW THE WHEEL AND TIRE ASSEMBLY TO SEPARATE FROM THE VEHICLE CAUSING A LOSS OF VEHICLE CONTROL.
