Component:
Steering
Manufactured:
06/30/2009 - 10/22/2009
Affected:
3,078
Defect:
Kenworth is recalling model year 2010 t2000, t800, t660 and w900s trucks manufactured between july 1 and october 23, 2009. the fasteners attaching the steering gear to the front drive bracket may have received insufficient torque during the installation process resulting in less than required clamp load.
Consequence:
The insufficient clamp load may allow the fastener(s) to become loose and fall away from the vehicle resulting in road debris. if multiple fasteners were to become loose, the vehicle steering may wander, which could result in a crash.
Correction:
Dealers will inspect and re-torque the steering gear mounting bolts free of charge. the safety recall is expected to begin during january 2010. owners may contact kenworth at 1-425-828-5440.
