The part is called a "Toe Link" if I remember right. I had to replace the one on the pass. side @ rear. Depending on who you talk to they will tell you its called a tie rod, and it goes in the front, because it seems that nobody understands that this not a solid axle in the rear like the older ones. I got real frustrated looking for mine, until I finally got a hold of a friend that's the parts manager at a Ford dealer ( he was on vacation and I couldn't wait). It only cost me around $17 (wholesale maybe?) and took me about 1/2 hour to replace (very easy). Make sure you adjust the end about the same length as old so you can drive it to get it aligned. Good luck
