How does IWE check valve work?
How does IWE check valve work?
The IWE is a vacuum system that engages and disengages the front wheel hubs. When the check valve goes bad, it looses the ability to hold the vacuum and the front wheel hubs tries to engage involuntarily.
What does IWE mean Ford?
Integrated Wheel End
For the uninitiated, Ford’s Integrated Wheel End (IWE) system is what locks and unlocks the front hubs when you change back and forth from 2WD and 4WD.
What is the meaning of IWE?
—used to say that one does not know the answer to a question and is surprised to have been asked it.
How do I know if the IWE solenoid is working correctly?
Yes, it sounds like the actuator solenoid is working to control vacuum, but it may have allowed water in over time, damaging the IWE at the hub. You can test the ability of the IWE to hold vacuum by connecting it to a hand held vacuum pump.
How does the IWE check valve system work?
Check valve The IWE system uses vacuum hubs that engage or disengage the front wheel hubs from the front halfshafts. The IWE solenoid receives enginevacuum from the vacuum reservoir.
Can a vacuum hose be removed from an IWE?
It will be necessary to remove the vacuum lines from each IWE down at the wheels to check for water being present. If no water is present at the vacuum line at the IWE, install the new solenoid with bracket. Reconnect all vacuum hoses. If water is present allow it to drain from the vacuum lines.
Where does the vacuum come from on an IWE F150?
The IWE vacuum solenoid receives vacuum from the vacuum reservoir. In 2WD mode, the IWE solenoid receives a ground path from the PCM, opening the vacuum valve to apply vacuum to the IWE ends. That DISENGAGES the front hubs from the front axle shafts.

How do you test a 4 wheel drive solenoid?
2.Check the fuses for the 4WD system and the solenoids. 3.Check the vacuum lines from the vacuum shift motor to the solenoids on the firewall. 4.Check the vacuum lines from the solenoids to the vacuum reservoir box behind the battery. 5.Check the vacuum reservoir box for cracks.
