These photos tell the tale of the task. The lower control arm pivots about the bushing's center sleeve, which was once completely encased in rubber, looking much like the urethane replacement. We can clearly see the bushing is worn to the point that it no longer functions. The metal-on-metal contact proved the source of our abnormal squeak. While this bushing was by far the worst, the others were significantly worn, having an adverse affect our vehicle's alignment. In the next issue we'll rebuild the control arms by installing the new bushings and ball joints, and then we'll reassemble the front suspension.
