What’s wrong with it?
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 RECALLING CERTAIN MODEL YEAR 2007-2008 KENWORTH AND PETERBILT VEHICLES MANUFACTURED FROM FEBRUARY 2, 2006 THROUGH APRIL 30, 2007.
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.
THIS CONDITION MAY RESULT IN UNIVERSAL JOINT FAILURE, ALLOWING THE INTER-AXLE DRIVELINE TO DETACH FROM THE AXLE.

What the record doesn’t say
- NHTSA’s recall file doesn’t say whether anyone was hurt.
- Whether one vehicle or seat has been fixed: only its maker, or NHTSA’s lookup with a VIN, can say.
- This recall names only model years before 2015, which have no pages here. Your VIN, at NHTSA, says which recalls are open on a vehicle.
- How many have been returned or fixed isn’t in the notice.
