The rear stabilizer bar on an Expedition consists of a large metal bar that connects to both ends of the vehicle. The end connections connect via nuts called link nuts which are torqued down to 75 ft-lbs. The bar is held in place by a set of brackets that connect to the vehicle frame and these bracket bolts also torque down to 75 ft-lbs.

The first step in replacing your rear end differential fluid is to jack the rear end of the vehicle up into the air. Be sure to use safety precautions so that no injuries occur. With the vehicle in the air you will have clear access to the rear differential. If you want to check the current fluid level you can remove the fluid fill plug which is a 3/8's ratchet sized bolt located about half way up the differential. If the fluid level is full the fluid should be directly below the level of the plug. If it is lower then your are currently low on fluid. To replace the fluid inside the diff you must remove the plate and allow for the fluid inside to seep out. Be sure to have a container to catch the fluid. Once the fluid stops flowing you can reinstall the plate by using some silicon sealant to help prevent leakage. The bolts for the plate should be torqued to 37 ft-lbs. With the plate reinstalled you can now take your new fluid and fill the rear end up through the rubber plug hole. Once done reinstall the plug to 25 ft-lbs and ensure that there are no leaks at the bottom of the cover.

To replace the rear shocks on a Expedition you will need to remove two sets of bolts/nuts. The first being the one located on the top of the shock. This one can be accessed by the truck or through the side of the vehicle with a wrench. Once this one has been removed the next bolt is located on the bottom of the vehicle. Once the bottom bolt has been removed the shock can be lowered out of the vehicle. The new part can now be placed in the vehicle much the same way that the old one has been removed. When tightening the bolts back up make sure to torque the top bolt to 75 ft-lbs. The lower bolt on the shock must be tightened to 75 ft-lbs.
