The problem
ON CERTAIN TRUCKS, THE NUT USED TO RETAIN THE STEERING SHAFT MAY OR MAY NOT BE A LOCK NUT THAT HAS THE LOCKING FEATURE. A LOCK NUT IS REQUIRED TO PROVIDE ADDITIONAL RESISTANCE TO ENSURE THAT THE NUT DOES NOT COME LOOSE.
Risk
IF THE NUT WERE TO COME LOOSE AND BE LEFT UNTREATED, THE STEERING SHAFT COULD POTENTIALLY SEPARATE INCREASING THE RISK OF A CRASH.
What owners should do
DEALERS WILL REPLACE THE STEERING SHAFT PINCH BOLTS AND LOCKNUTS FREE OF CHARGE. THE RECALL BEGAN ON AUGUST 24, 2007. OWNERS MAY CONTACT MACK TRUCKS AT 1-800-528-6586.
