So I might be buying a 1999 Ford expedition 4x4 for a DD.

What can you tell me about them, are they shit? Break a lot?


Learn me all your great knowledge PBB! :homer:

Other than the plugs blowing out of the heads they are decent for DD

It's about the same thing as an F-150 of that year, with a permanent camper attached.

The truck has a 4.6 in it, I heard of the spark plug holes being more of a problem on the 5.4 engines than anything.
It is a 5.4L issue, though it mostly happens on boosted trucks. The 4.6L has a few more threads in the heads for the plugs. Be careful tightning them though because they will still strip. The 4.6L is an excellent engine. It can last for a long time if maintained propperly. It is not extremely powerful and is really suited better in a car. Keep the plugs changed and check the coil boots/springs every time you change the plugs. The trucks have aluminum intakes, so they do not have the coolant leak issues that the PRE-PI car engines had.

Overall, it's a damn good engine, the trans is good too (put an auxillary cooler on it if you plan to tow). The rear is either an 8.8 or a 9.75. Both are good for a DD (4.6L 4x4 should be in the neighborhood of 3.73's). The frame is similar to that of an F150, so no issues there.

Good DD, but not so good on gas.

My 4.6 blew 4 spark plugs at various times before swapping to longer shank plugs, it was fixed with the heads still on the engine and it currently has 205,000+ miles on it...

Stay away from the rear air ride,they are prone to fail. There are also issues with the rear ac/heat sometimes from what I've read. They are big heavy trucks so don't expect any mileage over 16. There's an entire forum dedicated to them so check it out. I looked into getting one but will probably get a 95-96 bronco as its smaller and comes with the good ole 351

think I'm just going to stay away from an expedition altogether, I don't want to have to deal with that spark plug bullshit.

Just go back to my hunt for a crew cab powerstroke that hasn't been douched out.

Thanks for the input guys.

Bumping this to find out: Which Expeditions (year/option level) came with the air ride suspension?

Do what ya gotta do, but all cars/trucks have bullshit to deal with... What folks are saying is that it's really not that big a deal, and for the most part the things are pretty solid. I've done blown out plugs on a couple of 5.4's back in my dealership days. It's a prick, but not impossible by any stretch of the imagination. 4.6's were not prone to those issues.
