Front sway bar and endlinks install on 02-07 STi:
11.) Installing the endlinks was easy. Just be sure to follow the instructions given with the new endlinks regarding the order of the parts.
12.) Torque the endlink bolts to 45 N-m (33 ft-lbs), again with the car on the ground. I needed to add three washer spacers so that the endlinks were perpendicular to the ground when the car was on the ground. This is critical otherwise the endlinks might have premature wear and fail.
13.) The sub-frame went back on next by sliding it onto the bolts left on the car and then putting in the two bolts at the front of the car. I hand started all the remaining bolts and snugged them up before torqueing them down. The two bolts at the front of the car get tightened to 34 N-m (25 ft-lbs) using a 12 mm socket. The next three bolts on either side get tightened to 55 N-m (41 ft-lbs) using a 17 mm socket. And the last two bolts toward the rear of the car get tightened to 70 N-m (52 ft-lbs) using a 14 mm socket.
14.) Re-attach the plastic covers on each side of the sub-frame being careful to insert the small tab on the cover into a hole in the sub-frame first. Also, attach the plastic side cover to each side of the sub-frame with the single pop fastener that was removed earlier.
15.) Re-install the jack plate. The two nuts on either side get tightened to 30 N-m (22 ft-lbs). The four bolts get tightened to 70 N-m (52 ft-lbs). Re-install the front under-cover. The five bolts get tightened to 14 N-m (10.3 ft-lbs).
16.) Now go drive around and enjoy your new front sway bar and endlinks.
