Since we'll need to jack the truck up and lower the front end, I jacked the front end under the axle tube as high as my floor jack would go.
Using a 6-ton jack stand, position the jack stand under the frame rail behind the rear mount of the front leaf springs.
NOTE: The Excursion is one heavy beast. I noticed halfway through the install after wrenching on the frontend that the single jackstand was leaning a bit. I highly recommend positioning a 2nd jackstand about 1 foot behind the first one to ensure sturdiness. I eventually did this but did not get it pictured here.
