Changed my mind, and went ahead and attempted this yesterday. Removing the airbox (all of ten minute job) gives plenty of access to the most forward bolt on the drivers side. 13mm socket with a ratchet and two 10 inch extensions and a wobble end got that bolt out in 1 minute. Crawled under car and took awhile to get the rearward bolt on the drivers side. My ratcheting box wrench was too thick to fit into the tight recessed stock bushing bracket to get on the bolt, and not enough room for a socket/ratchet. Used a regular box wrench..1/4 turn at a time.
TIP: Make sure you have both sides of the front of the car up at the same time, evenly. Otherwise, the sway bar is pressed down on the side that is up in the air, making removal of the OEM bushing more difficult, and making installation of the replacment almost impossible until you get both sides of the car up evenly. Ask me how I know. Used plenty of the supplied grease on the bar and inside diameter of the Energy suspension bushing, tightened it down, and went to the other side. Even using the diagram on the Lincoln DVD, I could NOT figure out how to get that heater valve thing moved out of the way in order to get to the most forward bolt on the passenger side. Is it two 10mm bolts that need removal, or three bolts? Gave up after an hour of trying in that tight area. Will either re-attempt if someone tells me more info, or most likely take it somewhere and have a shop do it.
Observation. The stock bushing and bracket are noticeably wider and beefier with more surface area than the Energy Suspension. I sure hope these things do the job for the long haul.
