    Increase mpg?

    F1vel66a, when it comes to exhaust, you are having to play a balancing game here. Yes, lower back pressure allows the motor to not have to work as hard to push the exhaust gases out, but at the same time, the back pressure is what creates your low RPM torque. So, what can happen is out on the...

    Does Ford have its own branding for limited slip rears??

    whowey, if I remember right, the Ford axles use an Eaton limited slip device. That seems to stick in my head.

    changing rear end gears

    Captain, me personally, I can not see owning a truck without some sort of traction device in the rear. It makes a world of a difference as I see it. If for no other reason than when it rains, you have 2 tires pushing you around and when you feel the rear end start to chatter, you know you are...

    changing rear end gears

    for the cost and whatnot, getting a complete rear end is going to be the cheapest way to go. Also, like was mentioned, if you don't have the right tools, you will ruin a set of gears in a matter of miles. I paid around $1000 to have gears put into my truck for front and rear. So, you can plan...

    What size tires will fit with a body lift?

    Crazy, you can fit 35x12.5's on 8" wide rims (with 4.5" backspacing) and have full use of the truck and twist it up as much as you want. You step up to 9 or 10" wide rims and you may find that you will get rubbing during off-angle turns and whatnot. To have unlimited range with 9 and 10" wide...

    1997 Eddie Bauer 5.4l

    outdoors, take a look at the top of all the COPs for your truck. You should see a clear top to the COPs. Look closely, if you see a white line running around the edge of the coil or sometimes through the center, then your have a bad coil and what happened is some water got inside the COP and...

    Heat option I'd like to see

    You can make your own heating system. But, keep in mind that you will need to get some 1 ohm, wire wound resistors capable of around 300 watts of thermal heat. Then you can wire 2 of them in parallel with each other and run them off of a 30 amp relay. This will give you about 600 watts of...

    Question from Newbie:daystar&coilrite

    jack, not to ask a silly question, but when you remove the rear air bags, did you upgrade the springs in the rear to the non-air bag springs? Why do I say this? Simple, the air bag springs are weaker springs than for the non-air bag setups (this is what allows the truck to kneel). So, yes...

    cymru, you have the 2V heads. Only the Navigator got the 3V heads for the early years. It was one of the "benefits" of getting the higher end truck. Also, if you look at the cover over the throttlebody, the 3V head trucks had some writing on the cover that stated "3V".

    wheel spacers

    Exi, I think you are mixing things up here. wheel spacers move the rim way from the brake rotors. Coil spring (aka, lift) spacers lift the tire away from the body. As for pros and cons. The pro is that for little money, you can get a small amount of lift. The con, you are going to be more...

    Fog Light Help

    If you are upgrading a truck to put fog lights in it that did not come from the factory with fog lights, you have to upgrade 3 things electrically. 1) new headlight switch due to the non-fog light trucks getting a different headlight switch 2) add in fuse F27 (if not installed for another...

    Extra lighting options (no space behind grill or on roof)

    maverick, I would say to get yourself one of the bull bars and most of them come with 4 tabs for mounting more lights. That would put the lights up at about the headlight area without having to mount them in the grille. You have the right idea for the light styles for what you are after. I...

    suspesion problem

    hippo, sounds like one of your air control solenoids is starting to go and it is leaking severely. I am not all that up on the air ride system. So, without putting my hands on it, I am just using what I know and applying it. You can probably follow the air line back to the solenoid to help...

    traded 08 expy in and need advice on first gens.

    Nathan, feel in the driver's foot well area for wet carpeting. After that, take the truck out to a dirty/gravel parking lot and put the truck into 4 lo, make a small loop, then put it back in AWD. After that, take a look on the side of the block where the exhaust manifolds attach. See how...

    03 Expy Blowing taillight and brake fuse

    Scott, I will tell you to KISS (Keep it simple). Start off by removing both tail lights and unplugging them. Now, remove the 3rd brake light. With all of these disconnected, do a really good look at the plugs to make sure the pins look silver in color and the plastic is not melted. Next...

    Lifting 99 Expo! Need advice!

    bryce, going with bigger rims is a mixed bag as I see it. The current style is to go with 20" rims and off-road tires. Great if that is your bag of tricks. But, keep in mind that by going with bigger rims, you are also driving up costs and when out 4x4ing, you are putting the rim that much...

    98 expy headgasket help

    meats you do not need to pull the motor to pull the head off. I have pulled the head a few times and never removed the engine from the truck. The big trick is that you will be able to remove most of the bolts, but the lower back bolt will need to be lifted as you go to pull the head. There is...

    New to the expedition

    Wolf, your instrument cluster problem sounds like the infamous solder issue. The fix is easy. Getting to the fix is going to have you cussing. In short, the fix is pulling out a soldering iron and touching up the solder joints to where the cable joins the instrument cluster (if you look at...

    Exhaust

    Listen to the video. It does a pretty good explanation of the difference between X and H pipes. But, like he mentions, back pressure is key with engines, especially with truck engines. A freer flowing exhaust is great for 5,000 RPM power, but it can kill our 2,000 RPM power. Where do you...

    1st Gen Suspension Lifts

    Expeditionary, save the hassle, buy my truck. Cheaper in the long run (since I have done everything you are looking at doing except I have the 4" rancho vice the 6" Fabtech). He he he he he.

    Stupid Wipers

    bowman, it is possible that the connector is the root of your issues, but you need to also look at the wiring inside the column. This is especially true if you like to run the steering column up and down when getting in/out of the truck. It may be possible that some of the wires have gotten...
