Defect: Paccar is recalling certain model year 2008-2012 kenworth t2000, t660, t700, t800, and w900, as well as model year 2009-2012 peterbilt 365, 367, 384, 386, 387, 388, 389, and 587 trucks equipped with paccar mx engines. the oil module centrifugal spinner filter cap in the paccar mx engine may become loose, possibly allowing the cap to come off and engine oil to partially discharge from the oil module onto exhaust components.

Defect: Paccar is recalling certain model year 2008-2010 trucks equipped with trw steering shafts. the circumferential weld around the steering shaft tube that welds the splined tube to the non-splined tube may be mislocated. mislocation of the circumferential weld may allow the splined tube and non-splined tube to rotate relative to one another during a low speed, high torque turn, possibly resulting in a separation of the two tubes.

Why it matters: A separation of the splined and non-splined tubes would cause a loss of steering control and increase the risk of a vehicle crash.

Dealers will inspect the steering shaft using a weld placement gauge provided by trw. any steering shaft found to have been welded improperly will be replaced free of charge. the safety recall began on july 30, 2010. owners may contact kenworth at 425-828-5440 and peterbilt at 940-591-4196.
