The problem
THESE AXLES CONSIST OF A STEEL TUBULAR CENTER SECTION AND FORGED STEEL SPINDLES THAT ARE WELDED TO EACH END OF THE TUBE. EITHER SPINDLE CAN CONTAIN A CIRCUMFERENTIAL CRACK THROUGH A PORTION OF ITS CROSS SECTION.
Risk
THIS CRACK CAN REDUCE THE EFFECTIVE SERVICE LIFE OF THE SPINDLE AND CAUSE THE SPINDLE TO FRACTURE DURING NORMAL VEHICLE OPERATION INCREASING THE POTENTIAL FOR A VEHICLE ACCIDENT.
What owners should do
EATON WILL USE PORTABLE ULTRASONIC TESTING EQUIPMENT TO INSPECT EACH SUSPECT TRAILER AXLE. TRAILER AXLES CONTAINING DEFECTIVE SPINDLES WILL BE REPLACED WITH EQUIVALENT AXLES.
