Warnings
⚠️SAFETY-CRITICAL JOB: Improper steering column installation can result in loss of steering control, causing serious injury or death. If you are uncertain about any step, seek professional service immediately.
⚠️The clockspring (spiral cable) must be properly centered before installation. Failure to center the clockspring will damage it and can result in airbag non-deployment or inadvertent deployment.
⚠️Disconnect battery negative terminal and wait at least 3 minutes before beginning work to allow airbag system capacitors to discharge. Failure to do so can result in airbag deployment causing serious injury.
⚠️Never turn the steering wheel or allow the steering shaft to rotate when the column is disconnected from the rack. This will damage the clockspring and require replacement.
⚠Take multiple reference photos before disassembly, especially of electrical connectors, wire routing, and component positioning. The steering column has numerous electrical connections that must be reconnected correctly.
⚠All torque specifications marked as CRITICAL must be followed exactly. Incorrect torque on steering components can result in component failure and loss of vehicle control.
ℹ️This procedure requires a factory service manual for proper clockspring centering procedure and tightening sequences. Do not proceed without access to this information.

Procedure
- 1Remove steering wheel and airbagRemove the driver airbag module by accessing the retaining clips from the rear of the steering wheel (typically 2 clips on sides). Disconnect the airbag connector and horn connector. Mark the steering wheel position on the shaft. Using a steering wheel puller, remove the steering wheel retaining nut and carefully pull the steering wheel off the shaft. Do NOT hammer or pry on the wheel.⚠️Handle airbag module with care. Place removed airbag face-up on a clean surface away from the work area. Never place tools or objects on the airbag.
- 2Remove and secure clockspringRemove the clockspring cover if present. Disconnect all electrical connectors from the clockspring (typically airbag, horn, and steering wheel controls). Note the centering position indicator on the clockspring. Secure the clockspring in its centered position using wire ties or tape to prevent rotation. Remove the clockspring mounting screws and carefully remove the clockspring assembly. Store in safe location.⚠️The clockspring MUST remain in centered position. If it rotates from center, it must be re-centered per factory procedure before installation or it will be damaged during steering operation.
- 3Remove column covers and shroudsRemove the upper and lower steering column covers by removing the retaining screws. Remove any additional shrouds or trim pieces around the column. Disconnect the column wiring harness from any clips or ties attached to the covers. Set covers aside in organized manner for reassembly.Torque specCover Screws11 Nm (8 lb-ft)
- 4Disconnect electrical connectionsLocate and disconnect all electrical connectors on the steering column. These typically include: ignition switch, column lock actuator, tilt/telescope motors (if equipped), turn signal/wiper multifunction switch, and column harness connector. Label each connector with tape and marker to ensure correct reconnection. Release any harness clips securing wiring to the column.⚠Some connectors have secondary locks or sliding clips that must be released before disconnecting. Do not force connectors.
- 5Remove ignition switch and column lockIf ignition switch is being transferred to new column, remove the mounting bolts securing the ignition switch/column lock assembly to the column. This typically requires removing shear bolts or security fasteners. Mark the position of the ignition switch before removal if adjustable.ℹ️Ignition switch shear bolts may require drilling out for removal. Replacement bolts are typically included with new column or must be ordered separately.Torque specIgnition Switch Bolts5 Nm (4 lb-ft)
- 6Separate column from intermediate shaftWorking in the driver footwell area, locate the pinch bolt coupling connecting the lower steering column shaft to the intermediate shaft. Mark the relationship between the two shafts with paint marker. Remove the pinch bolt completely. Carefully separate the column shaft from the intermediate shaft by sliding apart. Do NOT allow the intermediate shaft to rotate after separation.⚠️Once separated, the intermediate shaft and steering rack must NOT be rotated. Secure the intermediate shaft to prevent movement which would damage the rack's centering and internal components.Torque specPinch Bolt30 Nm (22 lb-ft)
- 7Remove column mounting boltsSupport the steering column with one hand or have an assistant hold it. Locate the column mounting bolts (typically 2-4 bolts) securing the column bracket to the dash support structure. Remove all mounting bolts while supporting the column weight. Note the position of any shims or spacers at mounting points.⚠Column is heavy and awkward to handle. Ensure adequate support before removing final mounting bolt to prevent column from falling.Torque specSteering Column Bolts30 Nm (22 lb-ft)Mounting Bolts27 Nm (20 lb-ft)
- 8Remove column from vehicleCarefully guide the steering column out of the vehicle through the driver footwell area. Tilt and angle the column as necessary to clear the dash and surrounding trim. Feed any attached wiring harness through as you remove the column. Place column on clean protected work surface.
- 9Prepare and inspect new columnUnpack new steering column and inspect for shipping damage. Verify the new column is in the centered/straight-ahead position. If the column has a transport lock or pin, verify it is installed to prevent internal rotation. Transfer any necessary components from old column to new column (ignition switch, column lock, switches if applicable). Ensure clockspring on new column is properly centered.⚠Many replacement columns come with the clockspring pre-centered and locked with a transport pin. Do not remove this pin until column is fully installed and connected to the intermediate shaft.
- 10Install new column into vehicleCarefully guide the new steering column into the vehicle through the driver footwell, feeding the wiring harness first. Align the column with the mounting bracket holes on the dash support structure. Insert all mounting bolts finger-tight but do not fully tighten yet. Ensure any shims or spacers are in their original positions.
- 11Connect column to intermediate shaftAlign the column shaft with the intermediate shaft, ensuring the alignment marks made during disassembly are matched. Verify both shafts are in the straight-ahead centered position. Slide the shafts together fully. Install the new pinch bolt and tighten to specification following the factory tightening sequence if specified in service manual.⚠️Shaft alignment is critical. Both shafts must be in centered position before connection. Misalignment will damage clockspring and steering rack components.Torque specPinch Bolt30 Nm (22 lb-ft)
- 12Tighten column mounting boltsWith column connected to intermediate shaft, tighten all column mounting bolts to specification. Follow any specified tightening sequence from the factory service manual. Verify the column is properly seated against all mounting surfaces before final tightening.⚠Uneven tightening can cause column binding or misalignment. Follow factory sequence if specified.Torque specSteering Column Bolts30 Nm (22 lb-ft)Mounting Bolts27 Nm (20 lb-ft)
- 13Reconnect all electrical connectionsReconnect all electrical connectors to the steering column in reverse order of removal. Ensure each connector clicks fully into place and any secondary locks are engaged. Route the column wiring harness through original clips and secure with new wire ties as needed. Verify no wires are pinched or under tension.
- 14Install ignition components if transferredIf ignition switch or column lock was transferred from old column, install to new column in the same position as noted during removal. Install new shear bolts or security fasteners and tighten to specification. Verify ignition lock operates smoothly through all positions.Torque specIgnition Switch Bolts5 Nm (4 lb-ft)
- 15Install clockspring and steering wheelRemove the clockspring transport lock or securing ties if present (only after column is fully connected to intermediate shaft). Install the clockspring onto the column shaft ensuring it engages properly. Connect all clockspring electrical connectors. Install steering wheel aligning with marks made during removal. Install and tighten steering wheel nut to specification. Reconnect airbag and horn connectors. Install airbag module ensuring retaining clips fully engage.⚠️Verify clockspring is still in centered position before steering wheel installation. Do not remove clockspring centering lock until column is connected to intermediate shaft and steering is confirmed centered.
- 16Install column covers and trimReinstall upper and lower column covers and secure with screws to specification. Ensure no wires are pinched between cover halves. Install any additional shrouds or trim pieces. Reinstall lower dash panel and knee bolster.Torque specCover Screws11 Nm (8 lb-ft)
