Possibility that incorrect lower u- bolt brackets and/or upper u-bolt spacers made of manganese bronze instead of malleable iron were installed on the rear axle. These could break causing the rear axle to become disconnected from the vehicle and possibly result in loss of directional control and loss of braking action. (Inspect and install correct bolts as required.)
