Don't be scared of the track bar. If one of the bolts for it is loose, just jack up the frame and put some stands under it (not the axle, you want to un-load the axle), and crank both nuts down to their proper spec (if you need that I can llok it up for you, or someone else will pipe up with it). It's just that easy, if you have a few basic tools and a torque wrench. I'm also assuming you have a stock front end setup and not a lifted truck with an adjustable trackbar.
