Preparation

1. Park vehicle on level surface and set parking brake firmly
2. Turn steering wheel to center position with wheels pointing straight ahead
3. Turn ignition to LOCK position and remove key
4. Disconnect negative battery cable, then positive cable. Wait minimum 3 minutes before proceeding
5. Remove driver's seat to rearmost position for working clearance
6. Document all electrical connector positions with photos before disconnection
7. Verify replacement column matches existing column configuration (tilt/telescopic, paddle shifters, etc.)

Procedure

1. 1

   Remove lower dashboard panels and knee bolster
   Remove the driver's side lower dashboard panel by carefully prying out trim clips with trim removal tool. Remove the knee bolster panel beneath the steering column by removing Phillips screws and releasing clips. Store all fasteners and clips in labeled containers.
   ⚠Trim clips are fragile and reusable. Use proper trim tools to avoid breaking clips.
2. 2

   Remove steering column covers
   Remove the upper and lower steering column covers. The lower cover is secured by screws on the underside. The upper cover snaps into place and may have additional screws. Carefully separate the two halves and set aside. Note the position of any wiring harness clips attached to the covers.

3. 3

   Disconnect steering column electrical connectors
   Locate and disconnect all electrical connectors on the steering column including: ignition switch connector (usually green), steering angle sensor connector (gray), combination switch connectors (turn signal/wiper controls), paddle shifter connectors if equipped, and any other harness connections. Press release tabs fully before pulling connectors. Label each connector with tape if necessary.
   ⚠Do not pull on wires. Always grasp the connector body and press release tabs before separating.
4. 4

   Mark steering shaft alignment position
   Using paint marker or masking tape, make alignment marks across the steering column shaft and intermediate shaft joint at the pinch bolt location. These marks must line up exactly during reassembly to maintain proper steering wheel alignment. Take a photograph of the alignment for reference.
   ⚠️Accurate alignment marking is critical. Misalignment will result in off-center steering wheel and potential handling issues.
5. 5

   Remove steering shaft pinch bolt
   Locate the pinch bolt connecting the steering column shaft to the intermediate shaft below the dashboard. This bolt clamps the two shafts together. Using the appropriate socket, remove the pinch bolt completely. Note the bolt orientation and position of any washers. Support the intermediate shaft with wire to prevent it from dropping.
   ⚠️Do not turn the intermediate shaft or steering wheel after separation. Secure the intermediate shaft so it cannot rotate.

6. 6

   Remove ignition switch assembly
   If the ignition switch is mounted separately on the column, remove the mounting bolts securing it to the column. The ignition switch typically has two small bolts or screws. Disconnect any remaining electrical connections. Set aside carefully to avoid damage to the lock cylinder.

   Ignition Switch Bolts5 Nm (4 lb-ft)
7. 7

   Remove steering column mounting bolts
   Locate the four steering column mounting bolts that secure the column to the dashboard support bracket. These are typically two upper bolts and two lower bolts. Have an assistant support the weight of the column or use a suitable support. Remove all four mounting bolts while supporting the column weight.
   ⚠The steering column is heavier than it appears. Support the assembly to prevent it from falling and damaging components or causing injury.

8. 8

   Remove steering column from vehicle
   Carefully lower and pull the steering column assembly toward the driver's seat area. Guide the column out through the dashboard opening, being careful not to snag any remaining wiring or damage surrounding trim. Watch for any clips or brackets that may still be attached. Set the old column on a clean work surface.
   ⚠Avoid impacting the clock spring or airbag components during removal. Do not drop or strike the column assembly.
9. 9

   Transfer components to new column if necessary
   If the replacement column does not include all components, carefully transfer the ignition switch, combination switches, steering angle sensor, and any other components from the old column to the new one. Ensure the clock spring is centered on the new column (indicator marks aligned) and matches the centered steering wheel position. Follow manufacturer instructions for component transfer.
   ⚠️The clock spring MUST be centered correctly. An off-center clock spring will break during steering operation, disabling the airbag and potentially causing deployment issues.

    Install new steering column assembly
    Guide the new steering column assembly into position through the dashboard opening. Align the column with the mounting bracket holes. Ensure no wiring is pinched or trapped. Start all four mounting bolts by hand before tightening any of them. Once all bolts are started, tighten to specification in a cross pattern (upper left, lower right, upper right, lower left).
    ⚠Verify no wiring harnesses are pinched between column and mounting bracket before tightening bolts.

    Connect steering shaft to intermediate shaft
    Align the steering column shaft with the intermediate shaft using the alignment marks made during disassembly. The marks must line up exactly. Slide the shafts together ensuring full engagement of the splined connection. Install the pinch bolt with any washers in original orientation. Torque the pinch bolt to specification.
    ⚠️Alignment marks MUST match exactly. Verify the intermediate shaft has not rotated from its marked position. Incorrect alignment will result in off-center steering wheel.

    Reconnect all electrical connectors
    Reconnect all electrical connectors in reverse order of removal: ignition switch, steering angle sensor, combination switches, paddle shifters (if equipped), and any other harness connections. Ensure each connector clicks fully into place with locking tabs engaged. Verify no pins are bent and connectors are properly seated.
13. 13

    Install steering column covers and dashboard panels
    Install the upper and lower steering column covers, ensuring all tabs are properly aligned. Install cover screws to specification. Reinstall the knee bolster panel and lower dashboard panel, ensuring all clips are fully seated. Verify all trim pieces fit flush without gaps.

    Reconnect battery and initialize systems
    Reconnect positive battery cable first, then negative cable. Turn ignition to ON position (do not start engine). Verify all warning lights illuminate and then extinguish normally. Check for airbag system warning lights. The steering angle sensor will need to be calibrated - drive straight for 50-100 feet at low speed, then turn steering wheel lock-to-lock while stationary to allow the system to self-calibrate.
    ℹ️Some vehicles may require dealer-level scan tool to clear SRS codes and calibrate steering angle sensor. Check for persistent warning lights.

Reassembly

1. Ensure all electrical connectors are fully seated and locked - pull gently on each to verify
2. Verify steering wheel is centered with wheels pointing straight ahead
3. Check that all dashboard panels and trim pieces are secure with no rattles
4. Confirm all mounting bolts have been torqued to specification using the proper sequence
5. Verify no tools or parts have been left in the work area

Verification

• With engine off, turn steering wheel lock-to-lock to verify smooth operation with no binding or unusual noise
• Start engine and verify power steering functions normally without warning lights
• Check that horn operates correctly from steering wheel controls
• Verify all turn signal, wiper, and other steering column-mounted controls function properly
• Confirm airbag warning light extinguishes after initial bulb check (approximately 6 seconds after ignition on)
• Test drive vehicle in safe area at low speed to verify steering responsiveness and center position
• Perform steering angle sensor calibration: drive straight 50-100 feet, then turn wheel lock-to-lock while stationary
• Verify no warning lights remain illuminated on instrument cluster
• If SRS light remains on, use scan tool to check for codes or seek professional diagnosis - DO NOT drive with active SRS fault
