The affected vehicles may be missing required information from the certification label, specifically the tag or pusher axle the gross axle weight rating, suitable tire and rim information, and recommended tire pressure information. Without this information, the vehicles do not comply with the requirements of 49 C.F.R. Part 567, "Certification."

IF A CASTING BREAKS WHEN THE VEHICLE IS TRAVELING ON A ROADWAY THERE IS THE POTENTIAL FOR PIECES OF THE CASTING TO BECOME PROJECTILES AND THE SUSPENSION'S TRANSVERSE BEAM MAY DROP DOWN LOW ENOUGH TO CONTACT THE ROAD SURFACE.

Consequence

THIS COULD CAUSE SPARKS THAT COULD POTENTIALLY IGNITE AND CAUSE A FIRE.

Remedy

DEALERS WILL INSPECT AND REPLACE THE DEFECTIVE TRANSVERSE BEAM ASSEMBLIES FREE OF CHARGE. THE RECALL BEGAN ON JUNE 10, 2005, WITH LETTERS BEING MAILED TO PETERBILT OWNERS; AND ON JUNE 17, 2005, FOR KENWORTH OWNERS. OWNERS MAY CONTACT PETERBILT AT 940-591-4201 OR KENWORTH AT 425-828-5440.
