If any of you don't want the same problem of the grinding in the 04 -06 4x4 go to your local dealer and buy a new "redesigned" vacuum solenoid. My truck started making the same noise as seems like hundreds of others. This is caused by the old solenoid ingesting water and it getting into the 4wd vacuum system. The water can cause the IWE to try and engage 4x4 while in 2wd. This can cause damage to the hubs also. So if you own a truck between these years look on the passenger side firewall at the vacuum solenoid (could also be called an IWE solenoid) and if it does not have a Square plastic protective cover it could ingest water and cause damage. I bought the new part for $23 and put it on in about 10 minutes. The damage has already been done to mine but this could save people who haven't had the problem alot of money in the long run. Oh yeah it is easier to get to the part if you take the battery cover off.
I have a 2005 Lariat Screw 4x4. A month after I bought the truck, I wanted to use the 4x4, while engaging from 4x2 to 4x4, it started making a loud grinding noise, and did not go away when I tried to drive in 4x4.
I took it to the dealer the next weekend, they changed the vacuum solenoid, and the problem went away and never had a problem since.
This happened recently just 4-5 months ago.

the part number on mine is 9E441 A, make sure if you buy one it looks just like the old one except with a plastic cover on it. The funny thing is I found the part number on the service bulletin about this and it was the old part number. When I went to the dealer they put the number in and it referenced the new redisgned part number which should be the number I gave you. The old style was like 50 bucks and the same part with the new cover was only $23. The parts guy told me this is probably because ford knows they designed a faulty part and made the new one a cheap fix for us to do instead of them having to mess with it.

Yes, there is a black plastic shroud or shield that goes behind the solenoid. Either you have just a solenoid or a solenoid and a black back,1/2 sides, and top. I guess it keeps water from entering the cowl and laying on the electrical connector at the top of the solenoid.

im pretty sure thats what happened to me... happened 3 times today, i was headed out of town when it happened the first time, i stopped it felt like it popped in or out of gear then it was fine, went all the way to reno with no problems then coming back it did it again going about 70+ mph (the grinding didnt sound very good going that fast...) then i stopped and it popped in or out of gears again, i couldnt figure it out.. then i remember reading this post a few days ago and i figured out its not popping gears but its trying to go in 4wd... so i pulled out n went again, not but 100 yrds it did it again.. then i put it in 4wd then back into 2wd and it was fine the rest of the way home, tomoro ima take it in since its still under warrenty...

That's it. It is not totally covered. You can still see the solenoid with the shrowd. I guess you could add a piece of rubber for added protection.
