I am considering purchase of a 2000 F150 7700 5.4 4X4 XLT Ext cab 4Dr. it has 139,000 miles.
Any comments or expirience with this combo would be greatly appreciated. I am looking for fuel mileage figures/driveline problems to look for, etc. I know about the occasional problem with water leaking at the hood/cowel seal and getting the rear plugs wet/fouled. Anything else I need to know???

I am not afraid of high mileage Fords, this one is actually low miles for me as I own a 96 Econoline 4.9 Quigley 4X4 with 220,00 miles a 96 Explorer 4.0 with 180,00 miles and had a 97 Ranger with 170,000 miles when I sold it. No problems with any except for routine maintainence (Oil, filter, tune ups and brakes) none of them ever used any oil and always passed inspection.

Thanks in advance!

 

I have the same setup except mine is not a 7700. I also have a 3.55 rear end, whereas you should have a 3.73. I think that will help the mileage though. I get about 14 average mpg 60% highway, 40% city. Its hilly aroung here and the wind is usually blowing so I think I would get another couple of mpg's on the flats. I wouldn't expect seeing anything over 16 though. I went through a transmission at 88,000 miles(just bougth the truck). I suggest turning the overdrive off if it has any problem holding the speed you want. Other than that, i really have no complaints. Mine will pull a 6 or 7K stock trailer well with OD off unless the wind is fierce. I get anywhere from 8.5-11 pulling this.

 

Thanks, I did a search and came up with a lot of info. The current owner is a friend and told me 12 MPG is what it gets and I was using fuel mileage that his truck is getting as one of the factors to help determine the condition of the engine. seems like most with the same set up as the truck I'm looking at get about the same depending on how they are driven and what percentage is Hwy/Cty. I know how this guy drives and while he dosn't beat the truck he drives faster than I would on the same roads. Let's just say if he gets 12 I should get 14-15.

 

I wouldn't be scared of it. My 01 has been pretty much trouble free.

 

No real problems with my 7700. Issues related to the standard duty F150 do apply. Right now, I'm getting 13.5 mpg w/a 50/50 mix city/hiway. I also have a homemade FIPK, shortened exhaust (no muffler, exits in front of tire), predator tuner w/ no special tunes. My mileage has dropped by about a 1/2 mpg with these mods. In a recent trip, the 7700 got 17.18mpg with 95% hiway. It's gets about 10 mpg towing a 6000lb travel trailer averaging 45 mph.

If you do buy it... congrats and welcome to the 7700 - 250LD club.

I didn't know 7700 meant anything and was different from any other F150 but it sounds like there's something different about it. What is the difference? By the way thats what I have.

By the way, yes, I posted the wrong thread.. man I hate when I do that.

From Ford's Snowplow Prep Guide... this is for the 4x4, the 4x2 is similar without the 4wd.
