The defect
Kenworth IS recalling model year 2009 through 2010 t2000, T800, T660 and W900 trucks manufactured between november 12, 2008 and september 30, 2009. the axle u-bolts attaching the axle to the suspension leaf spring on certain ag400l rear suspensions may have received insufficient fastener torque during the installation process. the insufficient torque may allow the axle u-bolt to become loose, which may cause vibration in the rear suspension.
The risk
If multiple fasteners were to become loose, the rear axle may shift relative to the rear suspension leaf spring, which can result in loss of control and a crash.
The remedy
Dealers will inspect the axle u-bolts for visible defects, including bent and/or smashed threads and re-torque the axle u-bolts to factory specifications. the recall began on november 4, 2009. owners may contact kenworth at 425-828-5440.
