    Increase mpg?

    SCEBFEX, for me, it is based on calculated mileage from each fill up.

    new headlights

    Moose, write away. As the other members here will attest to, I am always getting questions and will assist however I can. I am a firm believer in the "Pay It Forward" concept. Besides, it is much easier to ask questions now than to order stuff, find out it doesn't do what you want or you...

    Increase mpg?

    enthusiast, I have pushed my expy to the limits with a short lift and have no problems diving into about any part of the truck. So, I have learned a lot and have a lot of diagrams that if I haven't dove into that part of the truck, can atleast give some helpful information. If you have a...

    Started timing chain job on 1998 ford expediton

    When you go to do the timing chain install, I think you will find the instructions that most people have are really poor and lead to tons of questions. I have had to remove the timing chains on my truck and this is what I will tell you for putting it all back together: You will put the key for...

    Installing an air horn..?

    Shadetree, what I have done in the past is left the factory horns where they are (wiring and all) and then wired the air horns in parallel via a switch. I use a single pole, double throw switch (SPDT, or ON-OFF-ON, switch). So, what this allows you to do is if you want the factory horn, you...

    How important is the "big three"?

    03ExpyMG, for you, I would say doing this mod is going to be important. The stereo system alone can be pulling upwards of 200 amps. So, you start adding in other truck loads and you are going to have your alternator maxed out. So, upgrading the wiring all the way around is going to be good...

    Drivebelt wont go back on

    ajreed, from what I can tell, you have the correct belt (belt length is right). So, you either have not pulled the tensioner enough to get the necessary slack in the belt or you have routed the belt incorrectly. It may be possible that you don't have the belt fitted into one of the grooved...

    B1802 Lamp turn signal rear output circuit failure

    Tito, I would start with plugging something into your trailer plug and seeing if that item flashes. If it does, then the problem is inside of the tail light and I would start with replacing the bulb, then next going to the plug for the entire tail light housing and making sure that is in good...

    How important is the "big three"?

    3expyMG, the effect that "the big 3" will have on your truck is dependent on how much power you are pulling. If you simply upgraded your alternator from the stock 95 amp unit to say a 150 amp unit, doing the big 3 is going to be very minimal. You upgrade to say a 250 amp unit and you are...

    new headlights

    Freeway, what are you trying to say, huh? Imagine, I have a lot more in my "bag of tricks" when it comes to this stuff. Gotta love a company that sends you to training on lighting and thermal cameras. The things you can learn if you simply pay attention. Moose, if you need any help, just...

    Increase mpg?

    F1ve, a lot of it depends on how you drive your truck when accelerating from a stop. If you tend to keep the RPMs down to around say 2500 RPM (when the truck would shift), then it will help with your mileage. Also, you may find that you tend to keep your truck empty of stuff where others will...

    new headlights

    Ok, I am going to give a quick run down of the difference between halogen bulbs and HID bulbs. They have a large (relatively speaking) bulb that is filled with a halogen gas (argon, neon, etc) with a thin wire inside the bulb being surrounded by the gas. As power is applied, the wire converts...

    laptop as codereader

    docraymund, if you have a smart phone, just use that. You can pick up an ELM327 OBD reader for around $15 USD and then you can link to it via blue tooth and you can download a free program called "Torque". From there, you have full access to read all the codes you want and also to monitor real...

    adjusting ride height with torsion bars

    axl rose, this is my view of things, doing minor adjustments to the torsion bars is not going to affect anything. But, if you do major twisting (ie, trying to get 2-3" out of the front end), you are forcing the ball joints to run closer to their max. So, now, when you max out the suspension...

    Quiet mud tires?

    axl rose, you are fighting contradictory things here. For a tire to be good in the mud, you need something that can clear itself of the mud. In general, the only way to do this is to have wide spacing between the lugs of the tire so the mud doesn't have something to stick to. The noise a tire...

    Increase mpg?

    fordentusiast, yes, I do have the tow package on my truck. The tow package has nothing to do with the RPMs that the truck is running. The RPMs at highway speed are a function of the rear end gear (atleast for the 4R70/4R100 tranny Expy's, you get into the 5 and 6 speeds, then things change a...

    Fuel problem, I think.

    archsu, you will need to measure the fuel rail pressure. If you connect the pressure gauge (connection is on the passenger side, will look like a tire valve stem right on top of the motor), then turn the key to the RUN position (do not start the engine), the pressure gauge should read 40-50 psi...

    Increase mpg?

    Big White, I will agree with you that Ford spends a lot of money to make a very good exhaust system. But, at the same time, they are also trying to meet a few other things (like a quiet exhaust system for the large percentage that don't want to rumble down the road). So, like with anything...

    DRL diy?

    AWD, look on the back of the A/C panel (both manual and the EATC module), look for a light blue/pink wire. This should have power to it only when the truck is in run. So, even if you turn the key to the ACC position, the lights will remain off. that would be my second choice.

    REALLY wide tires...

    RUB RUB RUB. All I have to say. Probably good for going straight, but as soon as you go to turn, you are going to be hitting a lot of body panels and bumpers. Going with a wider rim would be advisable, but that is only going to make your rubbing issue all the worse. You will most likely also...

    DRL diy?

    AWD, you are going to need to pull out the headlight switch and you will need to cut 3 wires. You will be cutting the tan/white striped wire, dark blue/orange striped wire, and the dark blue/white striped wire. You will need 3 separate relays unless you can find a relay capable of 15 amps per...

    1999 Expedition XLT

    sma, your transfer case motor has failed/froze. Unfortunately, this results in having to put in a new transfer case motor. Fortunately they are fairly cheap and easy to install.

    changing rear end gears

    whowey, I can understand what your worries are with a 16 year old and the truck with an axle like that. But, how do you trust her to drive the truck and not run over cars? Simple, you taught her how to drive and you observed how she drives. This is just one more part of that training for how...
