    Who likes this idea for a decal?

    I would say most of these decals would be on our expedition windows so you would hope whoever was reading it would get the point that its related to our vehicle. Keep it simple and to the point.

    Ideas for better gas milage?

    I've said this on other posts but one of my biggest gas milage gains were underdrive pulleys. And they aren't that expensive if you install them. $150 gained over 1mpg

    98 o2 sensor/ wheel hub / tie rods

    I would get some non flammable penetrating lube and spray it on the threads every night before parking it for a couple weeks. Worked wonders for getting the studs out of my manifolds. I didn't feel safe spraying pb blaster or anything flammable in that high temp area on a daily driver.
