| Investigations Summary: | This investigation was opened on Aug. 17, 1995. It was closed on Jan. 26, 1996. This investigation was opened to examine the failure mode and the risk to motor vehicle safety posed by allegations of rear axle separations. The rear axle shaft and housing design is typical of those in which the weight of the vehicle is carried on the axle housing. The left and right axle shafts, supported by roller bearings, are situated inside the axle housing. The inboard splined end of the axle shaft receives power transmitted from the differential assembly, providing torque to the rear wheels. The allegations are that the axle shaft fails, resulting in the separation of a wheel and axle hub assembly or the entire axle shaft and wheel assembly, depending on the location of the axle shaft failure. As identified by Chrysler, the subject rear axles are dana 35c and 35cm models, which have been used on the subject vehicles since the 1990 model year. A safety defect trend with respect to the subject axle shafts has not been identified. See hard copy resume for full text of summary. |
