The steering column is very susceptible to damage once it has been removed from the vehicle.The vehicle's wheels must be in a straight ahead position and the key must be in the LOCK position when removing or installing the steering column. Failure to do so may cause the air bag coil assembly to become off centered and may result in unneeded air bag system damage. In the event air bay deployment has occurred, inspect the coil assembly for any signs of scorching, melting or other damage due to excessive heat. If the coil has been damaged, replace it. The steering column should never be supported by only the lower support bracket, damage to the column lower bearing adapter could result.

  1. If equipped with an air bag system, disable the air bag system as follows:
    1. Turn the ignition switch to the OFF position.
    2.  
    3. Remove the SIR IG fuse in the supplemental inflatable restraint fuse block.
    4.  
    5. Remove the rear plastic access cover to the air bag module.
    6.  
    7. Disconnect the yellow 2-way connector and connector position assurance (CPA) inside the inflator module housing.
    8.  

  2.  
  3. Disconnect the negative battery cable.
  4.  
  5. Remove the air bag module attaching screws, then the air bag assembly from the vehicle.
  6.  


CAUTION
When carrying a live air bag module, make sure that the bag and trim cover are pointed away from you. Never carry the air bag module by the wires or the connector on the underside of the air bag module. In case of an accidental deployment, the bag will then deploy with minimal chance of injury. When placing a live air bag module on a bench or other surface, always face the bag and trim cover in the up position, away from the surface. Never rest a steering column assembly on the steering wheel with the air bag module face down and the column vertical. This is necessary so that a free space is provided to allow the air bag to expand in the unlikely event of accidental deployment. Otherwise, personal injury could result.

The air bag system coil assembly is easily damaged if the correct steering wheel puller tools are not used.

  1. Remove the steering wheel attaching nut, then using a suitable puller, remove the steering wheel.
  2.  
  3. Disconnect the electrical connectors from the steering wheel, then the rear steering wheel cover.
  4.  
  5. Remove the steering shaft trim panel. Remove the lower steering column trim panel and the steering column reinforcement plate.
  6.  
  7. Disconnect the steering column electrical connectors. Remove the brake transaxle shift interlock cable from the ignition switch.
  8.  
  9. Remove the steering column to steering shaft joint pinch bolt. Remove the upper and lower steering column mounting nuts and remove the steering column from the vehicle.
  10.  

To install:
  1. Installation is the reverse order of the removal procedure. Torque the steering column upper and lower mounting nuts to 10 ft. lbs. (14 Nm). Torque the steering column to steering shaft joint pinch bolt to 18 ft. lbs. (25 Nm).
  2.  
  3. Reactivate the air bag system as follows:
    1. Turn the ignition switch to the OFF position.
    2.  
    3. Connect the yellow 2-way connector and connector position assurance (CPA) inside the inflator module housing.
    4.  
    5. Install the SIR IG fuse in the supplemental inflatable restraint fuse block.
    6.  
    7. Install the rear plastic access cover to the air bag module.
    8.  
    9. Turn the ignition switch to the RUN position. Observe the INFLATABLE RESTRAINT indicator lamp.If the lamp does not flash 7 to 8 times and then remain off, there is a problem in the air bag system and further diagnostic testing of the system is needed.
