  A: To replace the air bag clock spring, disable the sir system and also remove the air bag Steering Wheel. Next you shall remove the Steering Wheel nut while taking note of the alignment mark on the Steering Shaft and the Steering Wheel. Once you pull the Steering Wheel off you are to pull out the tilt lever all the way and take off the tilt lever assembly. Pull out 2 torx(R) head screws from the lower shroud and then the lower shroud itself followed by 2 torx(R) head screws from upper shroud and upper shroud. Remove the retaining ring from the Steering Shaft and the air bag clock spring, then removing the wire harness straps from Steering Wheel column wire harness, discarding the old coil if replacing. During installation, the wheels should be aimed directly and the block tooth and centering marks should be on the 12 o'clock position. In case of centering, refer to the instructions mentioned on the notice of the coil assembly. The new air bag clock spring will be presence-centered. Tech service centering tab must not be removed unless installation is done. Air bag clock spring assembly should be aligned with horn tower on the turn signal cancel cam of the assembly and the new air bag clock spring should be slid onto Steering Shaft assembly and locked securely into groove with a retaining ring. Remove the centering tab and attach the upper shroud using 2 torx(R) head screws that should be tightened to 1.5 n.m (13 lb in); next, attach the lower shroud and fix it with 2 torx(R) head screws also tightened to 1.5 n.m (13 lb in). For the vehicles with a tilt column, align and slide the tilt lever handle into the steering column until it locks. The wiring should be fed into the Steering Wheel, the Steering Wheel should be aligned with the Steering Shaft mark, and it should be installed, connecting the nut and tightening it to a torque of 41 n.m (30 lb ft). Lastly, mount the air bag Steering Wheel module and turn on the sir system.
