Removal and installation To remove, position the front wheels in the straight ahead position first and then remove the ignition key followed by the disconnection of the negative battery terminal. When using models that have an airbag, allow at least 1 minute to turn off airbag system before proceeding. The next step is to take off the steering wheel and, inevitably, the clock spring. To fit the assembly into the steering column, remove the screws that hold the combination switch base plate in place, disconnect the wiring of the combination switches and withdraw the assembly. Unscrew the bottom dash panel below the steering column, unscrew the wiring of the ignition switch and the key reader, and unscrew the wiring of the steering column clip. Use quick drying paint to trace the correlation between the intermediate shaft and the steering gear by rotating the steering shaft so that it can be used during installation. Take off the pinch bolt and washer holding the intermediate shaft to the steering gear and then take off the steering column holding bolts and dismount the steering column to the steering gear, positioning the column out of the vehicle. When fitting, follow the removal procedure in reverse, making sure the marks left in the course of removing are all facing upwards at the time the steering column is pressed into place. Connect the pinch bolt and steering column retaining bolts to their required torque, firmly attaching the ignition switch and key reader wiring, the lower dash panel with its retaining screws firmly fastened and the rheostat wiring connected, then the clock spring (where applicable) then the steering wheel.
