The problem
VEHICLE DESCRIPTION: CHASSIS CABS. THE TAPERED HOLE IN THE DRAG LINK END THAT ATTACHES TO THE PITMAN ARM TAPERED BALL STUD MAY BE MACHINED TOO DEEP CAUSING THE HOLE TO BE OVERSIZED. A DRAG LINK WITH AN OVERSIZED HOLE MAY NOT "SEAT" THE PITMAN ARM TAPERED BALL WHEN ASSEMBLED. THIS COULD CAUSE HIGHER THAN NORMAL FRICTION BETWEEN COMPONENTS DURING OPERATION, AND POSSIBLY RESULT IN JOINT SEPARATION OR A BROKEN BALL STUD.
Risk
IF THE JOINT SEPARATED OR THE BALL STUD BRAKE WHILE THE VEHICLE WAS MOVING, STEERING CONTROL WOULD BE LOST.
What owners should do
DEALERS WILL INSPECT THE STEERING LINKAGE ASSEMBLY AND, IF NECESSARY, REPLACE THE DRAG LINK AND THE PITMAN ARM.
