Check against the official notice below — it lists the full affected range.
PACCAR is recalling certain 2011-2012 Kenworth trucks manufactured between October 18, 2010, and January 28, 2011, including the T270/370, T440/T470, T800, T660, W900, and C500 models. The recall involves slack adjuster housings that may contain a defect called a flow notch in the handle portion, which resulted from an error during the casting process. This flow notch can reduce the structural strength of the housing and cause it to fracture.
If a slack adjuster housing fractures, the wheel brake it controls will stop functioning, which could increase stopping distances and potentially cause the vehicle to pull to one side during braking if the defective adjuster is on the steer axle, creating a crash risk. Dealers will inspect and replace the slack adjuster housing as necessary at no charge. Owners should contact Kenworth at 425-828-5440.

IF THE SLACK ADJUSTER HOUSING WERE TO FRACTURE, THE WHEEL BRAKE TO WHICH THE SLACK ADJUSTER HOUSING IS ATTACHED WOULD NO LONGER FUNCTION, WHICH COULD INCREASE VEHICLE STOPPING DISTANCES, AND IF MOUNTED ON THE STEER AXLE, COULD CAUSE THE VEHICLE TO PULL TO ONE SIDE DURING BRAKING, INCREASING THE RISK OF A CRASH.
DEALERS WILL INSPECT AND REPLACE THE SLACK ADJUSTER HOUSING AS NECESSARY. THIS SERVICE WILL BE PERFORMED FREE OF CHARGE. THE SAFETY RECALL BEGAN ON MARCH 30, 2011. OWNERS MAY CONTACT KENWORTH AT 425-828-5440.
PACCAR IS RECALLING CERTAIN MODEL YEAR 2011-2012 KENWORTH T270/370, T440/T470, T800, T660, W900 AND C500 VEHICLES MANUFACTURED BETWEEN OCTOBER 18, 2010, AND JANUARY 28, 2011. CERTAIN CAST IRON SLACK ADJUSTER HOUSINGS, WHICH TRANSMIT BRAKING FORCE FROM THE BRAKE CHAMBER PUSH ROD TO THE BRAKE CAM TUBE, MAY INCLUDE A FLOW NOTCH IN THE HANDLE PORTION OF THE HOUSING DUE TO AN ERROR DURING THE CASTING PROCESS. A FLOW NOTCH IN THE HANDLE PORTION MAY REDUCE THE EFFECTIVE CROSS SECTION STRUCTURE AND CAUSE THE SLACK ADJUSTER HOUSING TO FRACTURE.
