Since the steering column is designed to collapse upon impact, it is recommended NEVER to hammer on it.

  1. Matchmark the relationship of the steering wheel to the steering shaft in order to assure proper alignment upon installation.
  2.  
  3. Using the GM Steering Wheel Puller tool No. J-1859-03 or equivalent, press the steering wheel from the steering column.

  1. Properly disable the SIR (air bag) system, then disconnect the negative battery cable. For details on disabling the air bag system, please refer to Chassis Electrical of this repair guide.
  2.  
  3. Remove the SIR inflator module from the steering wheel as follows:
    1. Remove the screws from the back of the steering wheel.
    2.  
    3. Carefully lift the module away from the wheel, then push down and twist the horn contact lead to the right in order to remove it from the cam tower.
    4.  
    5. Remove the Connector Position Assurance (CPA) retainer, then disengage the SIR wiring connector from the inflator module.
    6.  
    7. Carefully remove the inflator module and position it aside in a safe place. MAKE SURE THE MODULE IS FACING UPWARD to leave space for air bag inflation should the unlikely event of an accidental deployment occur.
    8.  

  4.  


CAUTION
ALWAYS be very cautious when handling a live (undeployed) SIR module. Always leave room for air bag expansion should a deployment occur. This means it should always be placed face up, without ANYTHING on top of it. You should also carry it facing away from you for the same reason.

  1. Loosen and remove the steering wheel retaining nut.
  2.  
  3. If applicable, disengage the horn lead assembly.
  4.  
  5. Matchmark the relationship of the wheel to the steering shaft. This is necessary to assure proper alignment upon installation.
  6.  
  7. Remove the wheel from the shaft using a suitable threaded steering wheel puller such as J-1859-03 or equivalent.
  8.  

To install:
  1. Make sure the turn signal lever is in the neutral (no signal) position before attempting to install the steering wheel.
  2.  
  3. Slide the wheel onto the shaft splines while aligning the matchmarks made earlier. DO NOT misalign the wheel more than 1 in. (25mm) from the horizontal centerline.
  4.  
  5. If applicable, engage the horn lead assembly.
  6.  
  7. Install the steering wheel retaining nut and tighten to 30 ft. lbs. (40 Nm).
  8.  
  9. Install the SIR inflator module
    1. Position the module at the steering wheel, then engage the SIR connector and install the CPA retainer.
    2.  
    3. Position the SIR wires into the channel in the lower right portion of the steering wheel.
    4.  
    5. Route the horn contact lead through the wheel and into the cam tower. Press the lead into the tower and twist to the right (to the locked position).
    6.  
    7. Install the module to the steering wheel (starting with the top) while making sure NONE of the wires are pinched.
    8.  
    9. Install the retaining screws through the back of the module assembly and tighten to 27 inch lbs. (3 Nm).
    10.  

  10.  
  11. Make sure the ignition is OFF , then connect the negative battery cable.
  12.  
  13. Properly enable the SIR system.
