Tools Required

Caution: When performing service on or around the SIR components or the SIR wiring, follow the procedures listed below in order to temporarily disable the SIR system. Failure to follow the procedures could result in the following:

•	Air bag deployment

•	Personal injury

•	Otherwise unneeded SIR system repairs

1. Disable the SIR system. Refer to SIR Disabling and Enabling .
2. Remove the inflator module. Refer to Inflatable Restraint Steering Wheel Module Replacement .
3. Remove the horn plunger from the steering column by pressing inward to the stop and rotating horn plunger 90 degrees.
4. Disconnect the steering wheel electrical connector.



5. Remove the retaining nut which secures the steering wheel to the steering wheel shaft.




Notice: When removing the steering wheel, use only the specified steering wheel puller. Do not hammer on the end of the steering column shaft. Hammering could loosen the plastic injections which maintain the steering column rigidity.

6. Install J 1859-A with J-36541-A or J 42578 to the steering wheel.
7. Remove the steering wheel using J 1859-A with J-36541-A or J 42578 .

1. Install the steering wheel to the steering wheel shaft.

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.

2. Install the retaining nut that secures the steering wheel to the steering wheel shaft.

Tighten
Tighten the retaining nut to 41 N·m (30 lb ft).




3. Connect the steering wheel electrical connector.
4. Install the horn plunger to the steering column.
5. Install the inflator module. Refer to Inflatable Restraint Steering Wheel Module Replacement .
6. Enable the SIR system. Refer to SIR Disabling and Enabling .
