Here is how you replace the ignition tumbler

Disable the SIR system. Refer to ZONE 3.
Remove the upper and lower trim covers. Refer to Steering Column Trim Covers Replacement.
IMPORTANT: The abrasion sleeve located on the steering column wire harness assembly must be reinstalled. Make note of what connector is coming out of the abrasion sleeve for installation purposes.

Remove the wire harness strap (2) from the steering column and the wire harness assembly (1).

Installation is the reverse of removal but please note the following important steps.

Install the switch. Use a small blade screwdriver to compress the electrical contact and move the switch into position. The electrical contact must rest on the canceling cam assembly.
Fasten the Torx head screws on the switch. Tighten the screws to 53 inch. lbs. (6 Nm).
Install the upper column cover and fasten the column bracket nuts. Tighten the nuts to 22 ft. lbs. (30 Nm).
Install the knee bolster and the steering column cylinder lock. Tighten the column cover Torx screws to 12 inch. lbs. (1.4 Nm).
Install the lower column cover and tighten the Torx screws 53 inch. lbs. (6 Nm).
Make sure the switch is in the OFF position and install the steering wheel.
Enable the SIR system (if equipped).
