Removal & Installation

Print

  1. Before servicing the vehicle, refer to the Precautions Section.
    NOTE
    Disconnecting the negative battery cable on some vehicles may interfere with the functions of the on-board computer systems and may require the computer to undergo a relearning process, once the negative battery cable is reconnected.


    NOTE
    If working near and/or around the SRS system and components, be sure to properly disable the SRS system. See disarming/arming the SRS system.


    NOTE
    For vehicles equipped with OnStar (RPO UE1), with battery backup, the backup battery is a redundant power supply to allow limited ONStar functionality in the event of a main battery power disruption to the OnStar module (VCIM). Do not disconnect the main vehicle battery or remove the OnStar fuse with the ignition key in any position other than OFF. Retained accessory power should be allowed to time out or be disabled by opening the driver-s side door before disconnecting power. Disconnecting power to the module in any way while the ignition is ON or with the retained accessory power activated may cause activation of the OnStar backup battery system and will discharge and permanently damage the backup battery. Once the backup battery is activated it will stay on until it has completely discharged. The backup battery is not rechargeable and once it is activated, it must be replaced.

  2.  
  3. Disconnect the negative battery cable.
    NOTE
    The wheels must be positioned in the straight ahead position. Place the ignition in the LOCK position and remove the key from the ignition. This must be done before disconnecting the intermediate shaft from the steering gear. Failure to do so will cause the SRS coil (clock spring) to become uncentered, which will cause damage to the SRS coil.

  4.  
  5. Remove the stoplamp switch.
    NOTE
    Failure to remove this switch may cause the switch to be damaged or thrown out of adjustment, resulting in malfunction or premature brake wear.

  6.  
  7. Remove the instrument panel filler panel and knee bolster.
  8.  
  9. Disconnect the steering wheel rotation sensor electrical connector, if equipped.

To install:


NOTE
Be sure to use new fasteners, as required.


NOTE
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 sealer are identified. 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.

  1. Installation is the reverse of the removal procedure.
    NOTE
    If a service replacement steering column is being installed do not remove the anti-rotation pin until after the column has been connected to the steering gear.

  2.  
  3. Using the GM diagnostic scan tool or aftermarket equivalent reprogram the necessary systems and components. Be sure to follow the scan tool manufacturer-s directions.
