The system includes an air compressor and air storage tank. An elongate primary hose is connected to the storage tank and extends along the vehicle frame, the primary hose having a plurality of outlet ports situated adjacent to respective vehicle wheel wells. A secondary hose includes a first end selectively coupled to a respective outlet port and a second end selectively connected to the impact wrench such that the impact wrench receives air flow from the storage tank.
