VEHICLE DESCRIPTION: CONVENTIONAL TRUCKS AND TRUCK/TRACTORS EQUIPPED WITH A FIREWALL ADAPTER PLATE FOR THE STEERING SHAFT BOOT. INSUFFICIENT CLEARANCE BETWEEN THE TOP OF THE STEERING SHAFT AND THE TOP OF THE OPENING IN THE ADAPTER PLATE CAN CAUSE THE STEERING SHAFT TO CONTACT THE TOP OF THE FIREWALL ADAPTER OPENING WEARING A GROOVE IN THE STEERING SHAFT. IF THE GROOVE IS ALLOWED TO WEAR DEEP ENOUGH, THE SHAFT CAN FAIL.
THE BRAKE RETURN SPRING CAN CONTACT THE HUB. FURTHER WEAR OF THE BRAKE LINING MATERIAL WILL LEAD TO WEAR OF THE RETURN SPRING AND THE SPRING CAN FAIL PREMATURELY.
Whether a recall was fixed on a particular car is known only to the manufacturer: check the VIN at nhtsa.gov/recalls.
