My truck will not always start. If I bang on the steering column, it will evatually start. How do I remove the ignition tumblar and replace it?

Disconnect the negative battery cable. Caution: When performing service on or near the SIR components or the SIR wiring, the SIR system must be disabled. Failure to observe the correct procedure could cause deployment of the SIR components, personal injury, or unnecessary SIR system repairs.
Disable the SIR system. Lower the hush and knee bolster.
Remove the steering column trim covers.
With the key installed, turn the key to the RUN position.

Install an allen wrench into the hole on top of the lock cylinder housing. Push down on the allen wrench to release the tab on the lock cylinder inside the lock cylinder housing.

Slide the lock cylinder out of the lock cylinder housing.

Installation Procedure

Install the key into the lock cylinder. Important: The gears between the ignition switch and the lock cylinder housing must be in the correct position. Failure to do so will cause a misalignment of the gears in the ignition switch and the lock cylinder housing, which may result in a NO START or BATTERY DRAIN.
Use a screwdriver to rotate the lock cylinder housing gear clockwise to the start position - allowing it to spring return into the RUN position.

Align the lock cylinder and install into the lock cylinder housing.
Install the steering column trim covers.
Install the hush and knee bolster.
Enable the SIR system. Connect the negative battery cable.
