  1. Set the steering wheel in the straight ahead position, so that the front wheels are pointing forward.
  2.  
  3. Disconnect the negative battery cable.
  4.  
  5. On models with the 2-spoke wheel, remove the two screws retaining the horn shroud and disconnect the horn contact.
  6.  
  7. On models with the 3-spoke wheel, remove the medallion cover from the center of the wheel by prying lightly around the edge with a small screwdriver.
  8.  
  9. On models with padded horn shrouds, use a suitable prybar to unsnap the shroud from the retaining clip.
  10.  
  11. Disconnect the horn lead.
  12.  
  13. Remove the steering wheel retainer nut.
  14.  
  15. Scribe an alignment mark on the steering wheel and steering shaft for reassembly.
  16.  
  17. Using a suitable steering wheel puller, remove the steering wheel from the steering shaft.
  18.  

Do not strike the steering column or use air tools to loosen the steering wheel nut. The impact may damage the steering column's energy-absorbing properties.

To install:
  1. Align the matchmarks on the steering column and wheel, and install the steering wheel on the shaft. Tighten the steering wheel nut to 22-29 ft. lbs. (30-39 Nm).
  2.  
  3. Reconnect the horn lead and install the horn pad.
  4.  
  5. Connect the negative battery cable.
  6.  
  7. Check the steering wheel spoke angle and test the operation of the horn.

CAUTION
The Air Bag system must be disabled before the steering wheel and steering column are removed. Failure to disable the system may result in system repairs and possible personal injury. Do not damage, cut, or attempt to alter the yellow Air Bag wiring harness.

  1. Turn the steering wheel so that the vehicle's front wheels are pointing straight ahead.
  2.  
  3. Turn the ignition switch to the LOCK position. Remove the key.
  4.  
  5. Disconnect the negative battery cable, followed by the positive battery cable.
  6.  
  7. Properly disarm the Air Bag system.
  8.  
  9. Use a Torx® driver to remove the driver's Air Bag module retaining screws from the back of the steering wheel.
  10.  
  11. Carefully lift the driver's Air Bag module straight out of the steering wheel. Disconnect the yellow 2-way connector from the Air Bag.
  12.  
  13. Remove the Air Bag module from the vehicle and place it face-up on a clean bench away from your work area.
  14.  


CAUTION
Always carry a live Air Bag with its trim cover and cushion pointed away from your body. When placing a live Air Bag on a bench or other surface, always point the trim cover up, away from the surface. Following these precautions will lessen the chance of personal injury if the Air Bag accidentally deploys.

  1. Disconnect the horn leads.
  2.  
  3. Make alignment marks on the steering wheel and steering column shaft.
  4.  
  5. Loosen and remove the steering wheel nut. Use tool No. J-29752 or an equivalent steering wheel puller to remove the steering wheel.
  6.  


WARNING
The steering wheel puller bolts may damage the Air Bag cable reel if they are threaded too deeply into the steering wheel.

To install:
  1. Check the alignment of the Air Bag cable reel.
    1. Turn the cable reel clockwise to the fully locked position. Do not turn the cable reel past the point at which you begin to feel resistance to its rotation.
    2.  
    3. Turn the cable reel about three turns in the opposite direction until the pointer on the cable reel is aligned with the neutral mark.
    4.  

  2.  
  3. Align the steering wheel matchmarks. Install the steering wheel and tighten the retainer nut to 25 ft. lbs. (34 Nm). Connect the horn leads.
  4.  
  5. Carefully connect the yellow 2-way connector to the Air Bag module. Install the Air Bag onto the steering wheel. Install the Torx® bolts while supporting the Air Bag module with your hand. Tighten each bolt to 6 ft. lbs. (8 Nm).
  6.  
  7. Properly arm the Air Bag system.
  8.  
  9. Connect the positive and negative battery cables.
  10.  
  11. Turn the ignition to the ON position, but don't start the engine. The AIR BAG warning light should turn on and flash on and off for seven seconds, and then turn off. This light sequence indicates that the Air Bag system is functioning normally. If the AIR BAG light doesn't come on, or stays on longer than seven seconds, the system must be diagnosed.
  12.  
  13. Check the operation of the horn buttons.
  14.  

HOMBRE
  1. Disable the Air Bag system.. For details on disabling the Air Bag system, refer to Chassis Electrical .
  2.  
  3. Disconnect the negative battery cable.
  4.  
  5. Remove the SIR inflator module from the steering wheel:
    1. Turn the steering wheel 90 degrees to access the rear shroud hole to the inflator module.
    2.  
    3. Carefully insert a screwdriver and push the leaf spring to release the pin.
    4.  
    5. Turn the wheel 180 degrees to access the remaining rear shroud holes.
    6.  
    7. Again, insert the screwdriver and push the leaf spring to release the pin.
    8.  
    9. Tile the module rearward from the top in order to access the wiring.
    10.  
    11. Disconnect the lead wire from the clip on the inflator module and from the clip on the steering wheel.
    12.  
    13. Remove the Connector Position Assurance (CPA) retainer from the module connector, then disengage the wiring.
    14.  
    15. 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.
    16.  

  6.  

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, remove the horn plunger contact.
  4.  
  5. Place scribe marks on the steering wheel and 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-A or equivalent.
  8.  

To install:
  1. 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.
  2.  
  3. If applicable, install the horn plunger contact.
  4.  
  5. Install the steering wheel retaining nut and tighten to 30 ft. lbs. (40 Nm).
  6.  
  7. 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. Secure the SIR lead wire to the clips on the steering wheel and the module.
    4.  
    5. Install the module to the steering wheel by pressing it firmly into the wheel until all 4 notched pins are engaged in the leaf springs. DO NOT pinch the wires during this.
    6.  

  8.  
  9. Make sure the ignition is OFF , then connect the negative battery cable.
  10.  
  11. Properly enable the SIR system.
  12.
