A pulling tool is provided with a rotatable drum having a cable wound thereon. A motor is drivingly connected to the rotatable drum and the rotatable drum and motor are disposed within a unique housing structure. The rotatable drum is driven by a planetary gear system that is disposed within the rotatable drum to provide a compact assembly. A belt and pulley system is provided for delivering torque from the motor to the planetary gear system. The rotatable drum is provided with a two-piece stepped construction that allows the planetary gear system to be assembled within the drum and allows for the initial wraps of a cable around the smaller diameter portion of the stepped drum.

A wheel end of a vehicle includes a knuckle and a wheel and wheel hub rotatably mounted to the knuckle. A CV-joint is positioned adjacent to the wheel hub. A clutch ring is slidable between engagement with one of the wheel hub and the CV-joint or both. A pneumatic annular actuator is connected to a shift fork that is engaged with the clutch ring for movement of the clutch ring between engaged and dis-engaged. The shift fork includes a base portion and an L-shaped section. The L-shaped section includes a plurality of slots therein to allow the shift fork to deflect and pivot when a misalignment occurs between the teeth of the constant velocity joint half shaft and the clutch ring during assembly of the CV-joint to the wheel hub. The pneumatic actuator includes an elastomeric diaphragm wall that includes a compliant stop extending axially therefrom.
