THE STEERING ARM USED ON THE EATON EFA-12FA FRONT AXLE MAY FAIL WHEN USED IN CONJUNCTION WITH ROSS HFB-70 POWER STEERING GEARS IF TORQUE LIMITING FEATURES ARE NOT MAINTAINED. A FAILED STEERING ARM WOULD CAUSE LOSS OF VEHICLE CONTROL AND COULD RESULT IN A CRASH WITHOUT PRIOR WARNING. CORRECTION: INSTALL A NONADJUSTABLE 1500 PSI POWER STEERING PUMP PRESSURE RELIEF VALVE TO LIMIT STEERING ARM FORCES. REPLACE STEERING ARM WITH A DESIGN CAPABLE OF WITHSTANDING HIGHER FORCES. ADJUST MAXIMUM POPPET VALVE SETTINGS TO 500 PSI AND ADJUST AXLE STOPS.
