JFYI.....if you need the hub actuators, they are $62 on Amazon....same mfr and appear identical to the $120 and $180 units. The Solenoid I would go Motorcraft as well as the the check valves. Keep in mind if the actuators are worn down from grinding, there is something in the vacuum system that caused it so its important to find the cause before ruining the new actuator. I learned the hard way.
