Upgrading to Polyurethane Tension Control Rod Bushings on the S13 240SX

The tension control rod is the part of the front suspension which keeps the lower control arm from moving forward and backward.

At this point there is a bushing, the only alternative being a ball joint, as it must flex in two directions at once.
