The problem
THE PITMAN ARM RETAINING BOLT MAY NOT HAVE BEEN TIGHTENED TO THE REQUIRED SPECIFICATIONS DUE TO A DESIGN CHANGE. INADEQUATE RETENTION OF THE BOLT TO THE OUTPUT SHAFT COULD ALLOW THE PITMAN ARM TO LOOSEN.
What owners should do
THE DEALER WILL INSPECT AND, IF NECESSARY, RETORQUE THE RETAINING BOLT TO PROPER SPECIFICATIONS AT NO CHARGE.
