The hazard

REVISED-DESIGN LOCK WEDGES ON REAR AXLE ASSEMBLIES MAY DISENGAGE FROM THE AXLE RETAINING NUT. IF THIS WERE TO OCCUR ON THE LEFT AXLE AND THE WEDGE BECAME JAMMED BETWEEN THE RETAINING NUT AND THE HUB, THE REATINING NUT COULD LOOSEN AND BACK OFF COMPLETELY, CREATING THE POSSIBILITY OF THE LEFT REAR AXLE, WHEEL AND BRAKE DRUM PARTIALLY OR COMPLETELY SEPARATING FROM THE REAR AXLE ASSEMBLY. PARTIAL SEPARATION WOULD RESULT IN LOSS OF REAR BRAKING CAPABILITY AND COMPLETE SEPARATION WOULD ADVERSELY AFFECT VEHICLE CONTROL.
