Hazard description
Certain heavy duty trucks equipped with axle assemblies which may have been manufactured with ArvinMeritor 12,000lb, 13,200lb axles, and Dana 9,000 front drive axles built with TRW 20-EDL ball sockets/drags links. The tie rod ball-socket bearings have a below specification case depth and/or hardness which can lead to premature wear out of the socket in some applications. If this condition occurs, the driver can lose steering control, possibly resulting in a vehicle crash. Correction: Dealers will replace the drag link assemblies.
