Re: im curious
You don't mean the actual actautor cable is hanging down do you? There should be a vacuum hose that connects to the rubber diaphragm side of the actautor, then the cable hooks to the other end, then when vacuum sucks the diaphragm, the cable pulls the slider in the front diff. to engage the front axle. At least thats how its Supposed to work. My cable was really messed up on mine, so I put one on from the boneyard,or go to a $dealer$ if you want new. Good luck.
