- Component:
- Latches/locks/linkages:hood:latch
- Manufactured:
- 06/30/2008 - 07/30/2009
- Affected:
- 4,796
- Defect:
- Kenworth is recalling certain model year 2009 through 2010 t660 tractor trailors manufactured from july 1, 2008 through july 31, 2009. the retaining pins securing the hood strut lock tube to the hood strut assembly may become loose and fall out allowing the lock tube to rotate on the strut assembly. in its normal operation the safety latch feature is automatically set and it prevents the hood from closing. with the hood closed and the retaining pins missing, the lock tube may rotate relative to the good strut resulting in a non-operational safety latch feature when the hood is opened.
- Consequence:
- A non-operational safety latch feature may not be detected by an operator increasing the risk of personal injury and/or vehicle damage should the hood unexpectedly close.
- Correction:
- Dealers will replace the pivot disc and lock tube retaining pins with a revised pivot disc and cap screws. this service will be performed free of charge. the safety recall began on july 15, 2010. owners may contact kenworth at 1-425-828-5440.

- Manufactured:
- 05/13/2007 - 04/19/2009
- Affected:
- 9,697
- Defect:
- Paccar is recalling certain model year 2008-2010 trucks equipped with trw steering shafts. the circumferential weld around the steering shaft tube that welds the splined tube to the non-splined tube may be mislocated. mislocation of the circumferential weld may allow the splined tube and non-splined tube to rotate relative to one another during a low speed, high torque turn, possibly resulting in a separation of the two tubes.
- Consequence:
- A separation of the splined and non-splined tubes would cause a loss of steering control and increase the risk of a vehicle crash.
- Correction:
- Dealers will inspect the steering shaft using a weld placement gauge provided by trw. any steering shaft found to have been welded improperly will be replaced free of charge. the safety recall began on july 30, 2010. owners may contact kenworth at 425-828-5440 and peterbilt at 940-591-4196.

- Defect:
- Paccar is recalling certain model year kenworth t660, t700, t800 and w900 vehicles manufactured from december 22, 2008, through august 2, 2010, and equipped with ag400l air disc brakes. the air disc brake caliper could be installed on the wrong side of the drive axle potentially causing interference with the suspension bracket and the rear suspension as the outermost brake pads wear and the floating caliper moves inboard.
- Consequence:
- As this interference gets larger, this could eventually lead to reduced braking performance, increasing the risk of a crash.
- Correction:
- Dealers will verify the correct orientation of the brake caliper and perform the necessary repair free of charge. the safety recall began on november 24, 2010. owners may contact kenworth at 425-828-5440.

- Consequence:
- The discharge of engine oil onto exhaust components which are hot, such as when the engine is under significant load, may cause a fire.
- Correction:
- Dealers will re-torque the oil module filter cap and install a secondary retention device on the secondary centrifugal spinner filter cap. this service will be performed free of charge. the safety recall is expected to begin during march 2011. owners may contact kenworth at 1-425-828-5440 and peterbilt at 1-940-591-4196.
