ok when i bought my truck some guy removed the vaccuum operated 4x4 and used a cable instead, one big problem with cable is that you have to jack the front axle off the ground and now engage it by hand while spinning one tire. would somebody throw so pictures on here of there front axle so i know what parts to get to return it to vaccuum operated thanks guys i hope you can help

 

You should just need the actuator itself, which most parts stores will sell, and the actuator housing. Then just run some vacuum lines to the switch on the T case
