18mm allen key (optional?)

Replace the old rod and worn bushing with the new unit:
for the rear bolts above, you may or may not need the 18mm allen key to tighten them while the nut is held from below.
After everything is tightened down to the specs in the fsm, lower the car. It would probably be a good idea to have the car re-aligned professionally after any kind of suspension work like this.
