VEHICLES WERE MANUFACTURED WITH REAR AXLES AND REAR BEARINGS THAT ARE INADEQUATE FOR THE LOAD THAT IS APPLIED ON THEM. CARRYING HEAVY LOADS AND TRAVELING ON ROUGH ROADWAYS MAY CAUSE DETERIORATION OF THE BEARINGS. WHEN THE BEARINGS BECOME WORN, HEAT BUILDS UP IN THE AXLE AND BEARING, AND MAY RESULT IN A BROKEN AXLE.
Consequence: Not supplied
Remedy: THE REAR AXLE ASSEMBLY INCLUDING WHEELS AND TIRES WILL BE REPLACED.
