To replace the air bag clock spring, first remove the sir system disabling it and performing the necessary precautions. Turn steering column to the center position and extract the Steering Wheel off the column. Take away the upper and lower trim covers. Examine the steering column if necessary for accident damage and then pull the wire harness strap. For example, in the event the Steering Wheel has pad control, the air bag clock spring and wire harness assembly is to be dismantled in one unit; then otherwise it can be severed off alone. For wheels with pad control, undo the wire harness assembly, then use snap ring pliers to snap off the retaining ring and pull out the air bag clock spring. If required, you should take out the wave washer. For installation,...place the wave washer back in position and align the block tooth on the Steering Shaft assembly to the 12 o'clock position and if reusing the existing coil make sure it is centered prior to installation. A new coil is pre-centered, and the centering tab should not be removed until the installation is finished. Pop the centering tab off if the air bag clock spring has one. In-line the air bag clock spring with the horn tower via the shaft lock or name orientation plate, slide it onto the Steering Shaft assembly and take the tab off, then secure the retaining ring in the snap ring pliers and make sure it fits in to the groove of the race and upper shaft assembly. For wheels with pad control, install the wire harness assembly then wire harness strap, and recite the upper and lower cover on trim. Lastly, replace the Steering Wheel onto the column and switch on the sir system.
