1. Lift the rear end of the car.
2. Remove the endlink from each end of the swaybar (14mm).
3. Remove the four bolts holding the swaybar brackets to the crossmember (12mm).
4. Pull the swaybar out either end.
5. Your new swaybar should come with it's own bushings. Grease them up (inside and out), and put them on the bar.
6. Slide the bar into place. MAKE SURE you have it above the control arms (I didn't; I had to remove and reinstall the bar to get it right).
7. Put the 4 bolts in that bracket the swaybar to the car. Tighten them to 23 ft-lbs.
8. Put the endlinks on the new bar. Tighten the nuts to 29 ft-lbs.
9. Put rear wheels back on.
10. Lower car.
