The problem
THE DRAG LINKS MAY HAVE BEEN INSTALLED INCORRECTLY ALLOWING DRAG LINK CLAMP BOLT TO AXLE BEAM INTERFERENCE. CONSEQUENCE OF DEFECT: DURING A TURNING MANEUVER, INCREASED STEERING EFFORT OR COMPLETE LOCKUP OF STEERING COULD OCCUR WITHOUT WARNING. THIS COULD RESULT IN LOSS OF TRUCK CONTROL AND A CRASH.
What owners should do
ASSURE THAT DRAG LINKS ARE INSTALLED TO CORRECT INTERFERENCE CONDITION.
