Summary

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 shaft 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, T200…
