Tools Required

1. Turn the ignition OFF.

Caution: This vehicle is equipped with a Supplemental Inflatable Restraint (SIR) System. Failure to follow the correct procedure could cause the following conditions:

•	Air bag deployment

•	Personal injury

•	Unnecessary SIR system repairs

In order to avoid the above conditions, observe the following guidelines:

•	Refer to SIR Component Views in order to determine if you are performing service on or near the SIR components or the SIR wiring.

•	If you are performing service on or near the SIR components or the SIR wiring, disable the SIR system. Refer to Disabling the SIR System.

2. Disable the SIR system. Refer to Disabling the SIR System in SIR.
3. Remove the inflator module. Refer to Inflatable Restraint Steering Wheel Module Replacement in SIR.
4. If there are no alignment mark on the steering wheel hub, scribe an alignment mark on the steering wheel hub in line with the mark on the steering shaft.
5. Loosen the steering wheel nut.
6. Position the steering wheel nut flush with the end of the steering column shaft.
7. Loosen the steering wheel using the following tools:

•	For Pontiac vehicles, use the J 1859-A and the J 42578 .

•	For Chevrolet and Oldsmobile vehicles, use the J 1859-A .

8. Disconnect the steering wheel controls electrical connector.
9. Disconnect the horn switch lead from the steering hub.



10. Remove the steering wheel nut.
11. Remove the steering wheel from the steering shaft.
12. Remove the steering wheel controls and the steering wheel controls harness from the steering wheel, if equipped. Refer to Steering Wheel Control Switch Assembly Replacement .

1. Install the steering wheel controls and the steering wheel controls harness to the steering wheel, if equipped. Refer to Steering Wheel Control Switch Assembly Replacement .



2. Route the SIR connector through the steering wheel.
3. Align the mark on the steering wheel with the mark on the steering shaft.
4. Install the steering wheel.

Notice: Use the correct fastener in the correct location. Replacement fasteners must be the correct part number for that application. Fasteners requiring replacement or fasteners requiring the use of thread locking compound or sealant are identified in the service procedure. Do not use paints, lubricants, or corrosion inhibitors on fasteners or fastener joint surfaces unless specified. These coatings affect fastener torque and joint clamping force and may damage the fastener. Use the correct tightening sequence and specifications when installing fasteners in order to avoid damage to parts and systems.

Important: This is a prevailing torque type fastener. This fastener may be reused ONLY if the following conditions are true:

•	The fastener and its counterpart are clean and free from rust.

•	The fastener develops 3 N·m (27 lb in) of torque against its counterpart prior to the fastener seating.

If the fastener does not meet these criteria, REPLACE the fastener.
5. Install the steering wheel nut.

Tighten
Tighten the nut to 45 N·m (33 lb ft).

6. Connect the horn switch lead to the steering hub.
7. Connect the steering wheel controls electrical connector.
8. Install the inflator module. Refer to Inflatable Restraint Steering Wheel Module Replacement in SIR.
9. Enable the SIR system. Refer to Enabling the SIR System in SIR.
10. Verify that the steering wheel controls operate properly.
11. Verify that the horn operates properly.
