Removal Procedure

    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.

    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: When removing the steering wheel, use only the specified steering wheel puller. Do not hammer on the end of the steering column shaft. Hammering could loosen the plastic injections which maintain the steering column rigidity.

    Important: In the event that deployment occurs, inspect the supplemental inflatable restraint (SIR) coil assembly wire for any signs of scorching, melting, or other damage due to excessive heat. If you find damage to the coil assembly, replace the coil assembly. Refer to Inflatable Restraint Steering Wheel Module Coil Replacement in SIR.

    Caution: This vehicle is equipped with a Supplemental Inflatable Restraint (SIR) System. Failure to follow the correct procedure could cause the following conditions:

       • Air bag deployment
       • Personal injury
       • Unnecessary SIR system repairs
    In order to avoid the above conditions, observe the following guidelines:
       • Refer to SIR Component Views in order to determine if you are performing service on or near the SIR components or the SIR wiring.
       • If you are performing service on or near the SIR components or the SIR wiring, disable the SIR system. Refer to Disabling the SIR System.

  1. Disable the supplemental inflatable restraint (SIR). Refer to Disabling the SIR System in SIR.
  2. Caution: Unless directed otherwise, the ignition and start switch must be in the OFF or LOCK position, and all electrical loads must be OFF before servicing any electrical component. Disconnect the negative battery cable to prevent an electrical spark should a tool or equipment come in contact with an exposed electrical terminal. Failure to follow these precautions may result in personal injury and/or damage to the vehicle or its components.

  3. Disconnect the negative battery cable.
  4. Important: If you are servicing the steering column or any column-mounted component, remove the steering wheel. Refer to Steering Wheel Replacement . If you are removing the steering column in order to gain access to the instrument panel components, leave the steering wheel installed on the column.

  5. Remove the steering wheel if needed. Refer to Steering Wheel Replacement .

Installation Procedure


    Object Number: 355262  Size: SH

    Important: Do not service the steering shaft and the steering column separately. If you find damage in either the steering shaft or the steering column, replace the unit as an assembly.

  1. Install the ignition switch to the steering column assembly. Refer to Ignition Switch Replacement - On Vehicle .
  2. Align the flat section of the steering shaft lower spline (1) with the pinch bolt hole in the steering shaft joint (2).
  3. Install the steering shaft (4) to the steering shaft joint (2).
  4. Secure the steering shaft joint with the steering shaft joint upper pinch bolt (2). Do not fully tighten the bolt.

  5. Object Number: 355260  Size: SH
  6. For models with automatic transaxles only, install the shift interlock cable (2) to the ignition switch.
  7. Secure the shift interlock cable with the screw (automatic transaxle models only). Refer to Interlock Cable Replacement in Automatic Transmission.
  8. Position the steering column assembly under the instrument panel.
  9. 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.

  10. Secure the steering column assembly with the 2 upper mounting bolts and the 2 lower mounting nuts. Do not tighten the upper mounting bolts fully.
  11. Tighten
