I "finished" installing the bushings today. I say finished without a sense of completion because the Energy Suspension bushings did not fit in my non-stock front leaf springs. I knew the previous owner had lifted the truck, but I never thought to check the bushing size until after I had pressed out the OEM units and realized my error.
My two main goals were accomplished however. The loose track bar is now tight and the front suspension no longer squeaks when cycled.
As a unforseen corollary job, I had to untwist a front brake line.
