I noticed that there was something missing. What exactly is that called? I'm so mindless right now in my life when it comes to trucks. I'm new to this. (Don't be so harsh with the comments, have heart.)
I had the same problem. It will lean real bad in corners so take it easy. That is the sway bar end link and it's $15.00 at autozone. Easy fix, no need to take tire off or anything. Just use vice grips on the middle section to hold it from turning and take off the bottom nut, remove. The new one is one long bolt with washers, bushing and a nut for the bottom.
