Well, after reading several posts from here, and reviewing the RSB on how to change plugs on my 2005 Expedition, I decided to give it a try.
2005 Expedition 5.4L 3 valve, 72k miles
Well, I got the first one out without much issue. Definately harder than a typical change, but adding the penetraiting oil was a big help.
Second one started well, and was acting like the first. Upon removal, it was only the top of the plug. the shield and the ceramic were still in the head. I put the thing back together and took it to the dealership.
They informed me they have to remove the body, or the engine to get them out.
Not to sound ignorant but what exactly do you mean by "top of the plug"? Do you mean the little metal knobby thing, or the body? I'm confused b/c you said the ceramic was still in there, which to me is the body of the plug. If the body is still in there I would think you could still get it out. I found that using a regular socket worked better than a plug socket b/c it was easier to feel that it actually had a hold of the plug base. Does that make sense?
On the 5.4, the plug has a very long electrode and a "shield" that extends a ways below the threads into the cylinder. So the hex part of the body came out fine, but the shield and the electrode were still in there.
The problem is that I none of my local shops were very familiar with this issue. Only one seemed to understand, but didn't have the tools, and told me they had not performed the replacement before. The dealership knew immediately what was happening. The difference in the labor rate was $92 (dealer) $75 (repair shop). for the $100 - $150 difference, I would prefer to have the dealer do it.
My complaint is that Ford hasn't acknowledged this is an issue, other than to post a TSB on it. I am going to call and file a complaint just in case they decide to do something.
The sad part is that between my Taurus having tranny problems, and the Expedition having this, I may not buy another Ford. I am that furious about it.
You after hearing all of this crap and other horror stories I think I will let the dealer do this. Hell I change motors in my Corvette and will do all other maintenance and repairs but this crap is not funny at all.

Here's an update: They did remove the Cab in order to access the plugs. The tech broke 7 of the 8 plugs! Because he removed the cab, he may have not followed the procedure, not sure. $1600 total.
Oh, did I mention the window regulators need to be replaced? They lubed them but it made the situation worse, so that will be another $500, and the rear wiper pivot needs to be replaced for another $250!
Yep. They told me removing the cab was easier than removing the heads or the engine. They said it was common for them.Eric
They may call it "removing the cab", but in essance what they do is disconnect the driveshaft and all the engine connections and lower the engine and suspension out the bottom. Now they have some room to work on the engine.
