IV. Background

On certain 2011 Model Year Tundra vehicles equipped with a 3-Joint type propeller shaft the rear propeller shaft slip yoke may have been improperly cast. The improperly cast yokes are from a specific production lot. In vehicles with a slip yoke from that lot there is the possibility that the slip yoke may break and the rear propeller shaft may separate at the joint. If this occurs the propeller shaft could contact the road surface which could increase the risk of a crash.
