When building a four-link suspension that also has a track bar, a joint is needed that can move in more directions than a solid Heim joint or rod end bearing. A bushing allows this and helps reduce noise transfer from the trail/axle up through the frame. Plus, if the poly bushing should ever wear out, it is a low-cost rebuild, whereas most rod ends require complete replacement.
