An apparatus to service the driveline of a vehicle is presented. The apparatus includes two members, a pivot element, and a bridge lock. The members each have an elongated handle segment and a jaw segment. The pivot element is configured to pivotally connect both members together near the jaw segments. The bridge lock is configured to be movably positioned along the handle segments. The jaw segments combine to define a profile which is adapted to secure to the splined coupling interface of a vehicle propeller shaft. The bridge lock is adapted to provide holding pressure to the handle segments, so as to lock the jaw segments when secured to the splined coupling interface.
