Tools Required

    • J 42640 Steering Column Anti-Rotation Pin
    • J 41352 Modular Column Holding Fixture

Removal Procedure

    Important: If the inflatable restraint module is deployed, inspect the SIR coil.

    Replace the SIR coil if the SIR coil exhibits any signs of damage caused by excessive heat.

  1. Disconnect the negative battery ground cable. Refer to Battery Negative Cable Disconnection and Connection in Engine Electrical.
  2. Caution: Refer to SIR Caution in the Preface section.

  3. Disable the SIR system. Refer to SIR Disabling and Enabling in SIR.
  4. Remove the inflatable restraint steering wheel module. Refer to Inflatable Restraint Steering Wheel Module Replacement in SIR.
  5. Remove the steering wheel. Refer to Steering Wheel Replacement .
  6. Remove the I/P left insulator. Refer to Instrument Panel Insulator Panel Replacement - Left Side in Instrument Panel, Gages and Console.
  7. Install J 42640 to the steering column.
  8. Notice: The wheels of the vehicle must be straight ahead and the steering column in the LOCK position before disconnecting the steering column or intermediate shaft from the steering gear. Failure to do so will cause the SIR coil assembly to become uncentered, which may cause damage to the coil assembly.

  9. Remove the intermediate steering shaft from the steering column. Refer to Intermediate Steering Shaft Replacement .

  10. Object Number: 161141  Size: SH
  11. Remove the transaxle shift cable from the steering column.
  12. Disconnect the steering column electrical connectors.

  13. Object Number: 305570  Size: SH
  14. Remove the steering column bolts.
  15. Remove the steering column nuts.
  16. Remove the steering column anchor cable from the bracket stud.
  17. Notice: Once the steering column is removed from the car, the column is extremely susceptible to damage. Dropping the column on its end could collapse the steering shaft or loosen the plastic injections which maintain column rigidity. Leaning on the column could cause the jacket to bend or deform. Any of the above damage could impair the column's collapsible design. If it is necessary to remove the steering wheel, use only the specified steering wheel puller. Under no conditions should the end of the shaft be hammered upon as hammering could loosen plastic injections which maintain column rigidity.

  18. Remove the steering column.
  19. Install the steering column onto J 41352 .

Installation Procedure

    Notice: If a service replacement steering column is being installed, do not remove the anti-rotation pin until after the steering column has been connected to the steering gear. Removing the anti-rotation pin before the steering column is connected to the steering gear may damage the SIR coil assembly.

  1. Remove the steering column from J 41352 .
  2. Install the steering column.
  3. Install the intermediate steering shaft to the steering column. Refer to Intermediate Steering Shaft Replacement .
  4. Remove J 42640 from the steering column.
  5. Install the steering column anchor cable to the bracket stud.

  6. Object Number: 305570  Size: SH

    Caution: In order to ensure the intended function of the steering column in a vehicle during a crash and in order to avoid personal injury to the driver, perform the following:

       • Tighten the steering column lower fasteners before you tighten the steering column upper fasteners. Failure to do this can damage the steering column.
       • Tighten the steering column fasteners to the specified torque. Overtightening the upper steering column fasteners could affect the steering column collapse.

  7. Install the steering column nuts. Do NOT tighten.
  8. 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.

  9. Install the steering column bolts.
  10. Tighten
    Tighten the steering column fasteners in the proper order:

    7.1. Tighten the steering column bolts to 24 N·m (18 lb ft).
    7.2. Tighten the steering column nuts to 24 N·m (18 lb ft).

  11. Install the transaxle shift cable to the steering column.
  12. Connect the steering column electrical connectors.
  13. Install the I/P left side insulator. Refer to Instrument Panel Insulator Panel Replacement - Left Side in Instrument Panel, Gages, and Console.
  14. Install the steering wheel. Refer to Steering Wheel Replacement .
  15. Install the inflatable restraint steering wheel module. Refer to Inflatable Restraint Steering Wheel Module Replacement in SIR.
  16. Enable the SIR system. Refer to SIR Disabling and Enabling in SIR.
  17. Connect the negative battery ground cable. Refer to Battery Negative Cable Disconnection and Connection in Engine Electrical.
