Hi All, I've had a CAD front axle from a 1996 Ford explorer , welded the spider gears up and rigged up to a cable disconnect in my 2002 ford ranger. Have done about 30000km on this setup and have had no issues, works great! However, I bought a 2007 ford ranger that I will be swapping it into and would like to get it working off of vacuum in lieu of a cable. My issue right now is, when I received the differential originally the vacuum diaphragm (actuator) was broken. I glued it back together to keep things sealed, but I can't seem to find the part number for this piece anywhere. I know what I need for solenoids, and how to wire things, but I just can't seem to find this diaphragm. If anyone can lead me in the right direction of the part number, it would be greatly appreciated!
