- 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.

- 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:
