Ditto on the idler, but before I got around to it, the steering damper helped a lot of the 'thuggathuggathuggathuggathugga' I heard after the steering was jolted by a bump or a rock.

Look at your sway bar mounting too. Mine had come loose and chewed up the centering collar that sits in the control arm on that retainer. When you torque the nuts to 20 ftlbf the bushings will be tightly compressed.
