A Steve and Chris mentioned, the track rod ball joints fit into a mounting block that itself has bushings that attach it to the frame. One of these bushings will get more that its share of power steering effluent if there's anything of a leak in the steering box. Plus they also wear over time.

The sway bar is the ~3cm tube that attaches the upper control arms on both sides of the car. There are bushings on the outer edges of the longitudinal section of the sway bar, and bushings on the ends where they fit into the upper control arms.
