The 5.4L 3-valve "mileage vs symptoms" thread!

[Tocapet]

Mine is not the blend door. It's the mode door just above the gas pedal. I took the actuator motor out day before yesterday. It seems like the door itself is blocked. I can move it by hand, but only about 15 degrees. I watched a video on Youtube from a guy that replaced his actuator and he could move the door lever almost all the way around. So I hesitate to buy the actuator until I can figure out what else is wrong. I took the actuator apart and some of the teeth on the gear wheel are stripped off. To get to the rest of it requires taking the console out and most of the dash. Not fun, and expensive if I take it somewhere. Might just have to live with it. I'm the 3rd owner of mine. It was a fleet/lease before and then the guy before me bought it. I got it from him and have had it 5 years. It still runs like a striped ape!

Year: 2007 XLT

Problems noticed:

I am a full-time RV traveler towing a 31' vintage 1971 Airstream.

1) Small amount of lift gate paint bubbling

2) Blend door actuator fail

3) Coils and plugs replaced

4) Fuel pump died at 226,000 miles

Love my Expedition. People are shocked when I tell them its 12 years old with 227,000 miles.

2010 XLT 4X4
86K MILES

Bought it with 77K miles. Had to change leaky, pounded out front struts. Went Bilstein. Rear pinion seal was leaking, front sway bar bushings, changed those. 3 out of four axle seals are leaking a little bit, power steering hose is leaking. Leaky bulkhead connector on the transmission (6R80) Couple minor spots of paint corrosion on the tail gate. 1-2 seconds of rattle on start up.

Overall I'm very happy with it, it's pulled all trailers I've wanted it to. It's excellent on road trips, tons of power for passing (I'm used to driving 4.0L Jeeps). Only complaint I have is the interior is a tan colored cloth. Gets dirty easily with kids/dogs. If I had to do it all again, I would have went with an EL/MAX for the extra room

Year: 2007 EL RWD

Mileage: 166,000

Problems noticed:

No engine problems!

1) fuel pump needed replacement at 135k from a cracked plastic piece

2) radiator replacement needed at 160k also crack in plastic

3) a/c condenser replaced, was leaking power steering fluid- replaced at same time as radiator at 160k

I also tow a travel trailer full time. (I've also made a lot of little non-critical repairs like the blend door actuator, window regulator, and head unit).

2013 Limited HD Tow
96,000ish
Bought 40,000ish

Replaced heated/cooled seats plugin to the controller because it’s ground burned out (common problem I’ve read)
Drivers side seat controls panel snaps broke (have it wire tied up)
Shift servo or something on the tranny recently replaced due to recall
Has a random clunk underneath (related to drive shaft bushing or something?)
A little paint bubbling on the lift gate
Powered step boards sensor flakes out for awhile on the passenger side front but then all of a sudden cleared up
Battery replaced
Stock tires replaced with Falken Wildpeaks
Replaced shocks/struts with Bilstein 4600s
Replaced several lug nuts after messing them up taking off the tires (btw, those crome-ish capped lug nuts are junk and stupid, learned to use the metric socket not the “equivalent” standard)
Sumo springs spring inserts on the back

My wife mainly drives it now and I drive her Mazda CX-9 because she loves the cargo space and seating space of the Expy, lol.

2009 EL

Bought at 160k, now at 175k.

Heater hose T leaked and was replaced with a brass fitting.

Blown tensioner at around 173k so I replaced all timing components.

Shocks are shot, trying to figure out what to go with.

Ac compressor is noisy, but still working great.

Bubbling paint on the rear hatch.

It's been a super great vehicle and by far our favorite of any we have had!
