Kenworth bearing surfaces of the extended lube universal joint that attaches the INTER-AXLE driveline to the drive axle may become prematurely worn due to breakdown of lubrication AND/OR excessive heat.
The short version
PACCAR INCORPORATED reported a problem with the power train axle assembly. Here is what owners need to know.
THE BEARING SURFACES OF THE EXTENDED LUBE UNIVERSAL JOINT THAT ATTACHES THE INTER-AXLE DRIVELINE TO THE DRIVE AXLE MAY BECOME PREMATURELY WORN DUE TO BREAKDOWN OF LUBRICATION AND/OR EXCESSIVE HEAT. PREMATURELY WORN BEARING SURFACES MAY RESULT IN THE U-JOINT BECOMING LOOSE AND/OR BINDING.
DETACHMENT OF THE DRIVELINE FROM THE AXLE MAY CAUSE THE VEHICLE TO LOSE POWER AND BECOME DISABLED IN THE ROADWAY. ALSO, THE DRIVELINE COULD DROP FROM THE VEHICLE INTO THE ROADWAY INCREASING THE RISK OF A CRASH.
PACCAR IS WORKING WITH ITS SUPPLIER TO REMEDY THE VEHICLES FREE OF CHARGE.
