| Defect Summary | Paccar is recalling certain model year 2007-2008 kenworth and peterbilt vehicles manufactured from february 2, 2006 through april 30, 2007. the bearing surfaces of the extended lube universal joint that attaches the inter-axle driveline to the drive axle may become prematurely worn due to breakdown of lubrication and/or excessive heat. prematurely worn bearing surfaces may result in the u-joint becoming loose and/or binding. this condition may result in universal joint failure, allowing the inter-axle driveline to detach from the axle. | |||||||||||||||
| Consequence Summary | Detachment of the driveline from the axle may cause the vehicle to lose power and become disabled in the roadway. also, the driveline could drop from the vehicle into the roadway increasing the risk of a crash. | |||||||||||||||

| Defect Summary | Kenworth is recalling 3,423 my 2004-2009 t2000, t800,t600, w900 and t660 vehicles. increased brake excitation in a certain vehicle configuration which includes bendix drum brakes, wide base low profile single tires, and an ag400 or ag460 rear suspension, due to its unique brake clocking and cam tube length, can cause fatigue and cracking to brake assembly components. | |||||||||||||||
| Consequence Summary | Cracking can cause a complete fracture of the cam tube, which could increase stopping distance and decrease parking brake hold capability. | |||||||||||||||
| Corrective Summary | Dealers will inspect the rear axle brakes assembly, replace cracked rear axle brakes assembly components where required, and install cam tube support brackets on all rear axle wheel ends free of charge. the recall is expected to begin or before july 25, 2009. owner may contact kenworth at 1-425-828-5440. | |||||||||||||||

| Defect Summary | Paccar is recalling 140 my 2005, 2007-2009 t800, w900, and t660 trucks. the caliper mounting fasteners attaching the air disc brake caliper assembly to the torque plate may have received insufficient torque during the installation process. the insufficient torque may allow the air disc brake caliper assembly to become loose and possibly separate from the vehicle. | |||||||||||||||
| Consequence Summary | This could result in reduced braking capacity and also a road debris hazard, increasing the risk of a crash. | |||||||||||||||
| Corrective Summary | Dealers will inspect air disc brake caliper assemblies and replace the caliper mounting fasteners and torque properly. this service will be performed free of charge. the manufacturer has not yet provided an owner notification schedule. owners may contact kenworth at 1-425-828-5440. | |||||||||||||||

| Consequence Summary | A failure may reduce vehicle brake performance, increasing the risk of a crash. | |||||||||||||||
| Corrective Summary | Dealers will install the cam tube support brackets on all of the rear axle wheel ends. inspect the rear axle brake assembly and replace it if cracked. the recall is expected to begin during november 2008. owners may contact kenworth at 1-425-828-5440. | |||||||||||||||

| During the pe odi learned that the subject vehicles are being disabled when the horton fan hub fails, due to the fan striking the radiator.apparently, warning signs of the impending failure are not always sufficient to give the driver time to pull off the highway.thus, when the failure occcurs, in some cases the vehicle is stranded and must be towed. odi has examined data which indicates that class vii and viii trucks are over represented in crashes when stranded on the highway or shoulder, as contrasted to light vehicles.further, crashes involving disabled heavy trucks being struck by light vehicles are more likely to have serious consequences. nhtsa has upgraded pe09-002 to an ea to further investigate this matter.odi will examine the warning symptoms and assess the risk of a crash in the event of a breakdown on the highway. | ||||||

| Summaryon july 13, 2010, the office of defects investigations (odi) opened an investigation on model year (my) 2007-2009 peterbilt tractors equipped with the (spl170xl extended lube inter-axle driveline).odi opened this investigation based on one vehicle owners questionnaire (voq) and certain peterbilt field reports.during the course of the investigation, odi reviewed paccar's ir (october 22, 2010) response with associated data related to warranty and complaint information, mined field data, interviewed customers and visited local dealers within the washington metropolitan area.paccarconducted testing regarding torsional loading and identified various causative factors contributed to this safety defect finding.the defect is a consequence of the bearing surfaces of the spl170xl extended lube universal joint that attaches the inter-axle driveline to the drive axle becoming prematurely worn due to a breakdown of lubrication and/or excessive heat.prematurely worn bearing surfaces may result in the u-joint becoming loose and/or binding.this condition may result in universal joint failure, allowing the inter-axle driveline to detach from the axle, which may cause the drive axle to separate from the vehicle, increasing the risk of personal injury or property damage hazard.odi learned that the affected population of the alleged defect extended to peer models within paccar.in summary, the following vehicles are being recalled: my 2007 and 2008 kenworth trucks, models t600, t660, t2000, t800 and w900 and my 2007/2008 peterbilt trucks, models357, 378, 379, 385, 386, 387, 388, and 389 allequipped with extended lube inter-axle drivelines manufactured by dana corporation.the recall affects vehicles manufactured between february 2, 2006 and april 30, 2007.at this time paccar has not yet identified a fix for the inner-axle safety defect and is currently conducting testing with the intent to provide a solution to the failure.odi will monitor the development of paccars testing and ensure a timely repair for the consumer.this investigation is closed. | ||||||
