What he said.

From what your saying, it sounds like the solenoid has been bad for a while.

Well I'm hoping by getting a new solenoid this will first fix the 4WD not engaging when I switch it....also fix it wanting to engage driving down the road....only thing is I'm worried as to how much damage has been done to the IWE's (hubs) its done it 3 times so far and they can't get me into the shop until Thursday.

From what the TSB said, it is the 04-06 models that had the problem, and now it is fixed with a water shield over it.

grinding noise...yep!

I have a 2005 150 stx with a manual shift transfer case (no **** just a lever), I to had this same problem but mine only seems to happen in bellow freezing weather, it makes the noise shift into 4wd it goes away. I took the truck to ford they replaced the silenoid and it worked fine until the next cold snap which was today, I left the driveway shifted into 4wd because it snowed went about a 100ft heard a loud pop from the frontend and now the 4wd doesnt work at all! Back to ford we go. goodluck.

Just wanted to let everyone know I didn't forget to post an update on this issue.....just ran in to the normal with our service department.....put the truck in the shop on Thursday 2 weeks ago and they said it would be ready Friday afternoon...so I called them at 4:30 Friday afternoon and they said they had an emergency vehicle come in and it was top priority....said it would be Monday and to call at 2....so no truck that weekend....called them at 1:30 Monday afternoon and they said that neither part was on site......DO WHAT....!!!! How can you promise a truck on FRIDAY and the parts weren't there from the get go.....so of course I was HOTT....so after the conversation on the phone which was not PG by no means they said they would call when the parts came in...

So parts are on sire and the truck is going in Wednesday to get the solenoid replaced and also some motor assembly switch for the A/C......its just so funny to me that I mentioned to them that it could possibly be the solenoid from the information I got from you guys....and just by chance this is what they are replacing......hmmmmmm.....I wonder if they even checked the 4WD system....but I will say I've been driving the truck for a week now and no issue's with the 4wd anymore....so I'm thinking the moisture was the ROOT cause.....guess only time will tell......!!

Is there anyway to get the moisture out.....or check it.......any low point drains on the vac. system....???

My truck has been doing the same thing to me lately and it all makes sense now. I noticed it really was doing it when it was really cold out. I am assuming this is when the moisture in the vaccume line froze and it was engaging the 4X4. Like stated earlier when I put it in 4X4 it went away. I read the entire post but still am having trouble following the instructions on how to resolve the issue on my own. What am I looking for and what do I need to do to get the moisture out of the line. Thanks

This exact thing happened to me yesterday with my 07 150. I slowed to a stop and she made a thud then nothing since then. It's a new truck under warranty. Should the dealer be aware of this and if they fix it do they fix to the upgraded version?....startin' to think i better make an appointment.....

Ok i think mine is doing the same thing, just started today. called dealer already and they are getting me in tomorrow. But Im worried as ive got to drive about 20 miles to get there.
Just to confirm. If you turn on the 4 wheel drive it quits. If I turn it off I can hear what sounds more like a muffler shield rattle coming from the passenger side front end and can only hear it when on the go pedal. If your not on the go pedal you cant hear it.
Also noticed that when slowing down or going real slow, there is a slight hum. Like what you would hear when you have a set of aggressive tires on pavement.

Well, got my truck back from the dealer, they got it fixed.
Said that my vacuum line was disconnected at the hub.

Service paper works says..
" Found that the vacuum lines were disconnected at the hub not allowing the hub
to engage and also causing the hub to not disengage allowing it to make a grinding
noise. Reinstalled the vacuum line retested all grinding noise was gone and 4wd does work correctly."

My only worry is I had to drive 20 miles to the dealership...what kind of damage did I do to it in the process. Alternated between 4wd and 2wd on the way over.??????
