Mine too
Great job on describing the IWE! My '05 reg cab (183,000 mi) just developed the same problem. It sounded like a dragging piece of thin metal banding strap under the left front wheel,(a high pitched grinding,dragging noise). I drove it down the hwy until I could hit the back roads and try a few things. After backing up in 2 wheel drive about 30 ft I shifted into 4 hi and drove about 3 miles,then back to 2 hi. That was enough to make it quit grinding and get me the other 30 mi home.
My friend at work had the same problem with his 05 or 06 Crew Cab not sure which year. The Ford dealer couldn't find his problem either.
***Update*** Went by the dealer and bought the new IWE solenoid that has the cover made into it. 50.00 and took 20 min to replace. FIXED! Great pics of the part at the link below.
Thanks for all the info!!!

IWE system
Great write up. I have a '05 crew cab that I am now experiencing this problem. I have a question regarding the disconnection of the intake until I can test the system. Is there any limitation on how fast you can drive or how long you drive around with this line disconnected? I am suppose to go on a trip next week and I will not be able to fix the problem until I return.
Thanks.
Thanks.

The solenoid behind the battery has two bolt/screws, 10mm I think. If you are careful you can replace it without removing the battery.
Check valves should only allow air to pass in one direction...
The easiest line to disconnect (on the 4.6L) for temporary operations, is the line between the solenoid and the intake manifold. There is a check valve in the line near several electrical boxes on the firewall on the passenger side. I unplugged the line there.

Well...my vacuum box was the last thing I checked and it was in two pieces. I wish I would've started there. Anyone know a price on these?? Also, if I just plug that vacuum line will my truck work fine in 2-wheel drive for a few days until I can get a new box? I tried plugging it and when I took it for a test drive it was still making the noise. Good times...thank for the help.

my buddy and i did this repair up at his shop over the weekend. took us a total of about 65 mins to replace the drivers side actuator and the vacuum line that went to the actuators themselves.
after performing the leak down test it was clear what parts were faulty and what needed to be replaced. got my actuator from tasca parts and used some vacuum lines that were laying around the shop.
total cost of repair, approx $100 for the parts (rush shipping) and $0 in labor as we did the repair ourselves. nothing to it. so glad the dreaded grinding noise is gone and my 4wheel drive is working like a champ.
Thanks to all who contributed to this thread.
