Well I’ve been busy trying to fix this expedition and suspension wise went ok minus a few bolts needing cut off. I ended up getting both from 4x4 actuators and a new solenoid that’s bolted by the fan shroud. I tried to drive it to see if was any better and when I turn wheel it feels like it’s binding up and I hear what sounds like a whining noise from mostly the passenger side. I know these are vacuum ran systems but not sure how the it’s suppose to be ran like where does it get the vacuum source from and is there supposed to be a light on when u but it in 4x4 I get nothing on the dash or no lights pop up. Also what is the part numbers or parts needed for the vacuum lines and check valves. I’m not even sure if mine are hooked up right and the check valves seem to work both ways like they are not doing anything .Im stumped on this car it’s my first 4x4 and I’m clueless
