The problem
THE DRAGLINK, A PART OF THE STEERING LINKAGE THAT TRANSMITS TURNING MOVEMENTS TO THE WHEELS, MAY LOOSEN OR FAIL AT ONE OF ITS CONNECTIONS. THIS IS DUE TO INADEQUATE CLAMPING FORCE OF THE THREADED CONNECTION ON THE VERTICAL BALL STUD. DIMENSIONS OF THREADED PARTS MAY BE BELOW SPECIFICATION LIMITS. LOOSENESS AT THE JOINT ACCELERATES WEAR ON THE THREADS.
What owners should do
PARTS WILL BE INSPECTED AND, IF FOUND TO BE OUTSIDE OF SPECIFICATION LIMITS, WILL BE REPLACED AT NO CHARGE.
