Defect
VEHICLE DESCRIPTION: HEAVY DUTY TRUCKS EQUIPPED WITH 10,000 OR 12,000 POUND DANA FRONT AXLES. A CONDITION CALLED BRAKE "SPRAG", WHICH IS CHARACTERIZED BY A NOISE AT THE END OF AN APPLIED STOP, CAN DEVELOP IN THE BRAKE SYSTEM. THIS NOISE IS THE RESULT OF A PULSATION OF THE BRAKE LINING WITH THE BRAKE DRUM DURING BRAKE APPLICATION. THESE NOISE VIBRATIONS OCCUR AT THE RESONANT FREQUENCY OF THE FRONT AXLE CROSS-TUBE ASSEMBLY AND CAUSE UNUSUALLY HIGH STRAIN FORCES IN THE THREADED PORTION OF THE TIE ROD ENDS THAT ARE CONNECTED TO THE CROSS-TUBE.
Risk
FAILURE OF THE TIE ROD END CAN CAUSE LOSS OF STEERING CONTROL AND POSSIBLY RESULT IN A VEHICLE CRASH.
What the manufacturer will do
DEALERS WILL REPLACE THE BRAKE LINING ON THE FRONT AXLE OF EACH VEHICLE WITH A LINING MADE OF A DIFFERENT COMPOSITION. IN ADDITION, THE TIE ROD ENDS WILL BE REPLACED FREE OF CHARGE.
