4x4 vacuum diagram?
I have a 2004 F150 5.4L 4x4 89,000 miles. I just replaced the Actuator in the Right front wheel because it was not unlocking. now the one on the driver side is doing to same thing!!! on occasion! I replaced the IWE solenoid, didnt change a thing. Does anyone have a diagram off where the vacuum lines run for the lockouts? I have traced the lines to behind the enigine where I can no longer see them? what or where is the vaccum being created from? thx for any help!!
