Removal Procedure

Notice: The front wheels of the vehicle must be maintained in the straight ahead position and the steering column must be in the LOCK position before disconnecting the steering column or intermediate shaft. Failure to follow these procedures will cause improper alignment of some components during installation and result in damage to the SIR coil assembly.

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.

  1. Disable SIR system. Refer to Disabling the SIR System in SIR.
  2. Remove the steering wheel. Refer to Steering Wheel Replacement
  3. Remove the SIR coil. Refer to Steering Wheel Inflator Module Coil Replacement

Installation Procedure

Notice: 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. Removing the antirotation pin before the column is connected to the steering gear may damage the SIR coil.


    Object Number: 210551  Size: SH
  1. Install the steering column while carefully aligning into the lower steering coupler.
  2. Handstart the following components:
  3. • The rear support bracket bolt
    • The forward support strap nut
    • A new forward support shear-bolt

    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.

  4. Tighten the following components:
  5. Tighten

        • Tighten the rear support bracket bolt to 22 N·m (16 lb ft).
        • Tighten the forward support strap nut to 22 N·m (16 lb ft).
        • Tighten the new forward support shear-bolt to 21 N·m (15 lb ft).
