heres what you need.
1 can penetrating oil (WD40 etc)
1 floor jack and jackstands
1 1/2" drive ratchet and proper size socket
1 Measuring Tape
2WD or 4WD but its the same deal
Id also clean under neath the truck with some simple green and the hose to clean any loose dirt from falling into your eyes. (no fun)
With the truck level, measure the distance from the center of the wheelwell lip to the top center of your wheel on each side. Make note the distance for each side, it will be important for two reasons. First you want to ensure that both sides are level when you're done, and second you want to limit the lift to no more than 2" from stock. (Any higher will cause stress to your CV joints if your truck is 4WD resulting in accelerated wear and possibly failure)
Now jack up the front end and secure on jackstands to take the pressure off the torsion bars. Slide underneath and find the two adjuster bolts located near the back of both torsion bars (towards the rear of the truck) and spray liberally with some penetrating fluid. Let it soak in for 10 mins. to free up the bolts. Using the ratchet, tighten up the bolts until they are almost to the end of their travel. This will torque up the torsion bars, causing them to lift the front end higher. Now lower the front end and take the same measurements as you did before you began, to determine the lift gained. Repeat the tightening/loosening of the bolts until both sides are level and lift gained is no more than 2".
Take the truck out for a 10 minute drive. This will cause the torsion bars to "settle" and will most likely give you 1.5-1.75" of final lift, which is ideally where you want to be. The rear can be lifted using either by adding an add-a-leaf (full length recommended) or new leaf pack or you can leave it. After you're content with the new height, be sure to take your vehicle to get an alignment for a toe set.
Doug finally got around to the Torsion bar adjustment.Easier than changing that monster air filter that they have.Thanks for the Info.The "Bob Bower"edition Expedition is coming along fine.Thanks again.
