Steering Column Trim Cover Replacement
Removal Procedure
Caution: Refer to SIR Caution in the Preface section.

1. Disable the SIR system. Refer to SIR Disabling and Enabling in SIR.
Caution: Unless directed otherwise, the ignition and start switch must be in the OFF or LOCK position, and all electrical loads must be OFF before servicing any electrical component.

Failure to follow these precautions may result in personal injury and/or damage to the vehicle or its components.

2. Disconnect the battery negative cable. Refer to Battery Negative Cable Disconnection and Connection in Engine Electrical.

Remove the retaining screws (3) from the lower steering column trim cover. Disconnect the closeout trim cover from the lower steering column trim cover.
Remove the retaining screw (2) from the upper steering column trim cover (1).

this is something that would be best done by the dealer due to the airbag being in the steering wheel , that being said if you wish to attack this on your own still you have to unplug any power [battery, back up battery, stereo amps stiffening capacitors etc] then there are some small screws on the back of the steering wheel that need to come out before the horn/airbag assembly will come out to allow you to disconnect and replace the steering wheel switches depending on the accessories on your truck you may also need to remove the steering column covers before you can acess the scews in the back of the steeringwheel. be VERY cautious of the airbag connectors and wires but you would still be safer and better off letting a dealer change those out for you.
