1998 Kenworth T300 Recall

Certain Kenworth vehicles manufactured between March 1996 and September 11,2001 model year T300 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. Failure of the tie rod end can cause loss of steering control and possibly result in a vehicle crash. Correction: 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.

A failure of this component (steering) may increase the risk of a crash or injury.

Authorized dealerships will inspect the vehicle and complete all necessary repairs free of charge (parts and labor).

THESE VEHICLES DO NOT COMPLY WITH C.M.V.S.S. 121 - AIR BRAKE SYSTEMS. THE ANTI-LOCK BRAKING SYSTEM (ABS) FOR REAR AXLE BRAKES WAS NOT PLUMBED INTO THE AIR SYSTEM ON THESE VEHICLES. THE AIR HOSES FROM THE RELAY VALVES WERE CONNECTED DIRECTLY TO THE SERVICE BRAKE CHAMBERS, RATHER THAN BEING CONNECTED THROUGH THE ABS MODULATOR. CORRECTION: AIR HOSES WILL BE REROUTED TO CONNECT THROUGH THE ABS MODULATOR.

A failure of this component (brakes) may increase the risk of a crash or injury.

Authorized dealerships will inspect the vehicle and complete all necessary repairs free of charge (parts and labor).
