The problem
VEHICLE DESCRIPTION: TRUCKS EQUIPPED WITH A DRIVELINE PARKING BRAKE. THE FASTENERS THAT CONNECT THE END OF TRANSMISSION COMPANION FLANGE TO THE PARK DRUM AND DRIVELINE MAY LOOSEN.
Risk
IF THIS IS UNDETECTED, THE FASTENERS MAY FATIGUE AND EVENTUALLY SHEAR OFF ALLOWING THE DRIVELINE TO SEPARATE, INCREASING THE RISK OF A CRASH.
What owners should do
DEALERS WILL INSPECT THE FLANGE FASTENERS FOR PROPER TORQUE AND REPLACE ANY FASTENERS FOUND LOOSE. IF THE FASTENERS ARE FOUND TO BE PROPERLY TORQUED, THEY WILL BE REMOVED, PERMALOCK WILL BE ADDED, AND THEN RETORQUED TO PROPER SPECIFICATIONS.
