Track Bars Track bars follow many of the same guidelines as control arms do, but since they are bent for axle clearance to begin with, it can be hard to tell a bent track bar from a “straight” one. Instead, if you are looking at an adjustable track bar, it’s helpful to call the manufacturer and ask what the recommended length is for a particular lift height. Check bushings as we mentioned before for control arms, but pay special attention to the bolts that go through the bushings. Most aftermarket track bars require larger-than-stock bolts, and you want little, if any, play in the metal sleeve in the bushing. Also, if the frame-side end is a ball joint-style joint, check it for wear by wiggling it back and forth. It should be tight, but not impossible to move by hand. Also, the locking nuts on adjustable track bars like to come loose, which can lead to excessive wear on the threads. If that’s the case, it is best to move on to the next track bar.
