Defect:
On certain trucks equipped with accuride aluminum wheels, the wheels were not properly pre-stressed. this allows cracks to develop over time.
Consequence:
This may eventually lead to wheel failure and possibly result in a vehicle crash.

Defect:
On certain heavy duty trucks equipped with arvinmeritor series 145 or 160 rear drive axles, some spindles were overheated during the heat treat process.
Consequence:

Affected:
30,995
Defect:
On certain tractors equipped with caterpillar diesel engines, the variable valve actuation oil line may wear against the sharp edge of the cylinder head if not positioned correctly.
Consequence:
The oil line may be cut on the cylinder head causing an oil leak and a possible fire.
Correction:
Caterpillar, in conjunction with paccar, will be conducting the owner notification and remedy for this campaign free of charge. owners may call caterpillar at 309-675-6496, kenworth at 425-828-5440, or peterbilt at 940-591-4201.

Campaign:
06V391000 on 10/12/2006
Component:
Power train:driveline
Manufactured:
03/14/2006 - 11/09/2006
Affected:
572
Defect:
On certain trucks equipped with chalmers rear suspensions, the adjustable torque rod end castings may be brittle. a brittle rod end casting may fracture without warning, causing the vehicles' rear axles to become misaligned.
Consequence:
This misalignment can cause the vehicle to lose directional stability at speeds that may result in a vehicle crash.
Correction:
Dealers will inspect the vehicles to determine if they were manufactured with a suspect torque rod end. if a suspect torque rod end is found, the entire torque rod will be replaced. the recall began on october 9, 2006. owners may contact peterbilt at 1-940-591-4196 or kenworth at 1-425-828-5440.
Notes:

Campaign:
06V461000 on 11/29/2006
Component:
Trailer hitches:fifth wheel assembly
Manufactured:
10/01/2006 - 10/26/2006
Affected:
86
Defect:
On certain trucks, an ra529 king pin release air valve was manufactured with the internal spool installed backwards. this results in the air option of the king pin release system being inoperable. to correct this situation, the vehicle's air lines were reversed rather than replacing the valve.
Consequence:
With the lines reversed, the king pin can be released without the driver's knowledge. when this occurs, the driver could drive away and the trailer could become disengaged, increasing the risk of a crash.
Correction:
Kenworth will inspect the king pin release system and suspect valve. if any vehicles have a nonconforming valve or incorrect plumbing, it will be replaced and re-plumbed. the recall began on november 29, 2006. owners may contact kenworth at 1-425-828-5440.
Notes:
Kenworth recall no. 06kw3.customers may also contact the national highway traffic safety administration's vehicle safety hotline at 1-888-327-4236 (tty 1-800-424-9153), or go to http://www.safercar.gov.
Campaign:
07V090000 on 03/08/2007
Component:
Service brakes, air
Manufactured:
05/22/2005 - 01/13/2007
Affected:
65
Defect:
Certain trucks fail to comply with the brake timing regulatory requirements of federal motor vehicle safety standard no. 121, "air brake systems." the brake valve was moved to the opposite rail, increasing the length of the air line, which in turn increased the wheelbase requiring a dual relay valve system. the vehicles were manufactured with a single valve system.
Consequence:
If stopping distance was limited, a vehicle crash could result.
Correction:
Dealers will convert the single relay valve to a dual relay valve system free of charge. the recall began on may 21, 2007. owners may contact kenworth at 425-828-5440.
Notes:
Kenworth recall no. 07kw2.customers may contact the national highway traffic safety administration's vehicle safety hotline at 1-888-327-4236 (tty: 1-800-424-9153); or go to http://www.safercar.gov.
Campaign:
07V107000 on 03/15/2007
Component:
Power train:automatic transmission
Manufactured:
02/05/2002 - 02/25/2007
Affected:
4,592
Defect:
On certain trucks, the wiring, parts, or transmission programming required for the auto neutral feature to function as designed were either not installed, connected, or programmed properly.
Consequence:
If any of these conditions exists, the transmission will not automatically shift into neutral when left in drive with the parking brake set engaged. the vehicle could move without warning increasing the risk of a crash.
Correction:
Dealers will inspect the affected vehicles to ensure the auto neutral feature functions properly and, if needed, will make the necessary repairs free of charge. the recall began on may 9, 2007. owners may contact kenworth at 425-828-5440.
Notes:
Kenworth recall no. 07kw3.customers may contact the national highway traffic safety administration's vehicle safety hotline at 1-888-327-4236 (tty: 1-800-424-9153); or go to http://www.safercar.gov.
Campaign:
08V099000 on 03/03/2008
Component:
Service brakes, air:slack adjusters
Manufactured:
09/06/2004 - 01/18/2008
Affected:
130
Defect:
Paccar is recalling 130 my 2005-2007 kenworth c500, t800, w900, and peterbilt models 357 and 379 tractor trailers equipped with fabco slack adjusters on sisu axles. the slack adjusters may fail as a result of a fatigue crack rendering the slack adjuster inoperative. this could reduce braking effectiveness.
Consequence:
Reduction in braking capacity could increase the risk of a crash.
Correction:
Dealers will inspect and replace the slack adjusters free of charge. the recall began on march 21, 2008. owners may contact kenworth at 1-425-828-5440 and peterbilt at 1-940-591-4196.
Notes:
Kenworth recall no. 08kw2 and peterbilt recall no. 208c.customers may also contact the national highway traffic safety administration's vehicle safety hotline at 1-888-327-4236 (tty 1-800-424-9153), or go to http://www.safercar.gov.
Campaign:
08V485000 on 09/23/2008
Component:
Suspension
Manufactured:
07/06/2003 - 09/10/2008
Affected:
130
Defect:
Paccar is recalling 130 my 2004-2009 t2000, t800, t600, w900 and t660 kenworth trucks built with an ag400 rear suspension, long stroke brake chambers, and wide base tires (super singles). these vehicles may develop an increase in lateral and vertical axle movement. this movement may cause part or parts of the brake assembly (brake cam tube support, brake chamber bracket, brake chamber, brake spider) to develop fatigue cracks, possibly resulting in the failure of the part or parts within the brake assembly.
Consequence:
A failure may reduce vehicle brake performance, increasing the risk of a crash.
Correction:
Dealers will install the cam tube support brackets on all of the rear axle wheel ends. inspect the rear axle brake assembly and replace it if cracked. the recall is expected to begin during november 2008. owners may contact kenworth at 1-425-828-5440.
Notes:
Kenworth recall no. 08kwb. customers may contact the national highway traffic safety administration's vehicle safety hotline at 1-888-327-4236 (tty: 1-800-424-9153); or go to http://www.safercar.gov.
Campaign:
08V487000 on 09/24/2008
Component:
Engine and engine cooling:engine:diesel
Affected:
4,883
Defect:
Paccar is recalling 4,883 my 2006-2009 kenworth t600, t660, t800, w900, t2000 and my 2008-2009 peterbilt 365, 367, 379, 384, 386, 387, 388 and 389 trucks. inadequate stiffness of the diesel particulate filter (dpf) bracket could result in separation of the dpf from the chassis.
Consequence:
A vehicle crash could occur if another vehicle strikes the dpf on the roadway.
Correction:
Paccar is working with caterpillar to repair these vehicles (please see 08e041). owners may contact caterpillar at 1-800-447-4986 or kenworth at 1-425-828-5440 or peterbilt at 1-940-591-4196.

Campaign:
09V239000 on 06/28/2009
Component:
Service brakes, air
Manufactured:
04/22/2003 - 09/16/2008
Affected:
3,423
Defect:
Kenworth is recalling 3,423 my 2004-2009 t2000, t800,t600, w900 and t660 vehicles. increased brake excitation in a certain vehicle configuration which includes bendix drum brakes, wide base low profile single tires, and an ag400 or ag460 rear suspension, due to its unique brake clocking and cam tube length, can cause fatigue and cracking to brake assembly components.
Consequence:
Cracking can cause a complete fracture of the cam tube, which could increase stopping distance and decrease parking brake hold capability.
Correction:
Dealers will inspect the rear axle brakes assembly, replace cracked rear axle brakes assembly components where required, and install cam tube support brackets on all rear axle wheel ends free of charge. the recall is expected to begin or before july 25, 2009. owner may contact kenworth at 1-425-828-5440.
