The problem
TRUCKS WERE ASSEMBLED WITH THE LEFT-HAND LOWER CONTROL ARM TO FRAME REAR NUT TIGHTENED BELOW THE SPECIFIED TORQUE. LOW TORQUE ON THIS NUT MAY ALLOW THE ATTACHMENT BOLT TO LOOSED AND SUBSEQUENTLY FATIGUE AND BREAK. THE BOLT BREAKAGE CAN CAUSE THE LEFT HAND CONTROL ARM TO SEPARATE FROM THE FRAME.
Risk
IF THIS OCCURS, A LOSS OF VEHICLE CONTROL AND A CRASH COULD RESULT.
What owners should do
DEALERS WILL TIGHTEN THE LEFT-HAND LOWER CONTROL ARM TO FRAME REAR NUT TO THE PROPER TORQUE SPECIFICATION.
