Howdy all, new to this forum but already have some interesting information to share. My Expedition has always been a little unstable with any type of sudden change in direction so I decided to change the front shocks. to my surprise the link on the drivers side sway bar was missing thus being the cause of my problem. I will be making a call to the parts department tomorrow. I always thought something was wrong with the suspension but never this. so keep this in mind when trouble shooting a suspension problem.
