Power train › Axle assembly
The defect
On certain pinion gears, p/nos. 129737 and 127420, manufactured on december 4, 2007, and assembled into the axle assembly of tandem-rear or single drive axles installed as original equipment for certain international, paccar, and volvo heavy trucks, wrong induction hardness process settings were used resulting in excessive hardness of the pinion gears.
The risk
The excessive hardness can potentially result in the threaded end of the pinion breaking off. this failure could result in driveshaft disconnecting from the axle, which would cause loss of vehicle power. it IS also possible that the driveshaft may separate from the vehicle possibly resulting in a vehicle crash.
The remedy
Dana IS working with the vehicle manufacturers to notify owners and have their vehicles repaired free of charge. owners should contact their vehicle manufacturer for more information.
