  3. Remove the steering wheel. Refer to Steering Wheel Replacement .
  4. Remove the SIR coil. Refer to Inflatable Restraint Steering Wheel Module Coil Replacement in SIR.
  5. Disconnect the electrical connectors (3) from the multifunction switch (1).
  6. Remove the driver's insulator panel. Refer to Instrument Panel Insulator Panel Replacement - Left Side in Instrument Panel, Gages, and Console.

  12. Remove the steering column lower mounting bolts (3).
  13. Remove the steering column upper mounting bolts (1).
  14. Notice: Once the steering column is removed from the vehicle, the column is extremely susceptible to damage. Dropping the column assembly on the end could collapse the steering shaft or loosen the plastic injections, which maintain column rigidity. Leaning on the column assembly could cause the jacket to bend or deform. Any of the above damage could impair the columns collapsible design. Do NOT hammer on the end of the shaft, because hammering could loosen the plastic injections, which maintain column rigidity. If you need to remove the steering wheel, refer to the Steering Wheel Replacement procedure in this section.

  15. Remove the steering column (2) from the vehicle.

Installation Procedure

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.
