Summary

THE EQUALIZING BEAM SHAFT OF THE TANDEM AXLE SUSPENSION WERE MANUFACTURED FROM AS-ROLLED SAE4140 STEEL RATHER THAN THE SPECIFIED ANNEALED SAE4140. THESE SHAFTS CAN FRACTURE INSIDE THE BEAM AT THE TOE OF THE WELD.

Consequence

VEHICLES ARE SUBJECT TO VEHICLE TILT AND POSSIBLE ROLLOVER IN THE EVENT THAT BOTH EQUALIZING BEAMS, ON THE SAME SIDE OF THE VEHICLE, EXPERIENCE A SIMULTANEOUS SHAFT FAILURE. AFFECTED SUSPENSIONS CAN ALSO DROP AND CONTACT THE ROAD SURFACE GENERATING SPARKS WHICH COULD IGNITE FLAMMABLE MATERIAL.

Remedy
