The problem
THE INVOLVED VEHICLES CONTAIN DEFECTIVE BALL STUDS THAT WERE IMPROPERLY HEAT-TREATED AND THUS CONTAIN CRACKS. THESE STUDS, LOCATED IN THE PITMAN ARM, COULD EVENTUALLY FRACTURE IN THE THREADED PORTION UNDER THE RETAINING NUT.
What owners should do
THE DEALER WILL REPLACE THE DEFECTIVE PITMAN ARM BALL STUD WITH A NEW ONE, WITHOUT CHARGE.
