## Narrative

The technician was removing the rear driveline from ST 1921.  The mechanic was prying the driveline away from the yoke on the differential as he inadvertently placed his left index and middle finger in the area of the upper u-joint by the carrier bearing.  As the bottom end came free, the fingers were pinched causing lacerations, requiring sutures.
