Madison Avenue likes to tell us that we can, in fact, have it all. But when it comes to automobiles,...
THE REAR BRAKE DRUMS WERE NOT CORRECTLY MACHINED. AS THE VEHICLE IS DRIVEN, LOSS OF WHEEL CLAMP LOAD CAN RESULT FROM THIS CONDITION. ONCE CLAMP LOAD IS LOST, ALL TIRE LOADS ARE DIRECTLY TAKEN BY THE WHEEL STUDS. THIS LOADING CAN CAUSE FATIGUE FAILURE OF THE WHEEL STUDS.
IF THIS OCCURS, A WHEEL COULD SEPARATE FROM THE VEHICLE, AND A CRASH COULD OCCUR WITHOUT PRIOR WARNING.
REPLACE REAR BRAKE DRUMS.
