This procedure replaces the upper steering shaft on a 2011-2014 Ford F-150 with the 3.5L EcoBoost engine, addressing common issues like clunking or binding in the steering column.
Warnings
⚠️The steering system is safety-critical. Improper installation can result in loss of vehicle control and serious injury or death.
⚠Never turn the steering wheel with the intermediate shaft disconnected, as this can damage the clockspring and disable the airbag system.
⚠Ensure the front wheels remain pointed straight ahead throughout this procedure to prevent clockspring damage.
ℹ️The battery does not need to be disconnected for this procedure unless removing the steering wheel.

Parts
- Upper steering shaft assembly × 1 — Use OEM specification
- Intermediate shaft bolt (if not included with shaft) × 1 — Use OEM specification
Preparation
- Park vehicle on level surface and set parking brake firmly
- Ensure front wheels are pointed straight ahead and note steering wheel position
- Chock rear wheels to prevent vehicle movement
- Allow engine to cool completely if recently driven
Procedure
- 1Access the steering columnRemove the lower steering column cover by removing the screws (typically 2-3 screws). Pull the cover down and away from the column. Remove the upper steering column cover in the same manner, noting the location of all mounting points.Torque specCover Screws12 Nm (9 lb-ft)
- 2Mark shaft alignmentUsing a white paint marker or masking tape, mark the alignment between the upper steering shaft and the intermediate shaft at the lower coupling. This ensures proper reassembly alignment. Also mark the relationship between the upper shaft and the steering column.ℹ️Accurate alignment marking is critical for maintaining proper steering wheel position after reassembly.
- 3Remove lower coupling boltLocate the pinch bolt at the lower end of the upper steering shaft where it connects to the intermediate shaft. Using a combination wrench and socket, loosen and remove the pinch bolt. This bolt may have a lock nut; if so, remove the nut first. Note the orientation of the bolt for reinstallation.⚠Support the intermediate shaft to prevent it from dropping when disconnected.
- 4Disconnect lower couplingCarefully separate the upper steering shaft from the intermediate shaft by pulling the shafts apart. You may need to use a flat-head screwdriver to gently pry open the coupling. Do not force; if binding occurs, verify the pinch bolt is completely removed.⚠Do not allow the intermediate shaft to rotate or turn the steering wheel from this point forward.
- 5Remove upper mounting fastenersLocate the mounting bolts that secure the upper steering shaft assembly to the steering column housing (typically 2-3 bolts). Remove these bolts using the appropriate socket. On some models, these may be accessed from inside the cabin above the pedal assembly.Torque specMounting Bolts31 Nm (23 lb-ft)
- 6Remove upper steering shaftCarefully slide the upper steering shaft assembly upward and out of the steering column. You may need to tilt or angle the shaft to clear the column housing and dashboard structure. Take note of any bushings, seals, or spacers that may remain in the column for reinstallation.ℹ️Inspect the removed shaft for wear patterns, particularly at the splines and bearing surfaces, to confirm the failure mode.
- 7Prepare new upper shaftInspect the new upper steering shaft assembly to ensure it matches the removed part. Transfer any reusable components from the old shaft if required (such as mounting brackets). Clean the steering column bore and intermediate shaft splines with a clean rag to remove any debris or old grease.ℹ️Some replacement shafts come with pre-applied grease; do not remove this lubricant.
- 8Install new upper shaftInsert the new upper steering shaft into the steering column from above, carefully aligning it with the column bore. Ensure any bushings or seals are properly positioned. Slide the shaft down until it reaches the intermediate shaft coupling position. Align the shaft according to the alignment marks made during disassembly.⚠Verify the steering wheel position remains straight ahead before proceeding.
- 9Secure upper mountingInstall the upper mounting bolts through the steering shaft assembly into the column housing. Start all bolts by hand to ensure proper threading. Torque the mounting bolts to specification using a torque wrench in a cross-pattern if multiple bolts are present.Torque specMounting Bolts31 Nm (23 lb-ft)
- 10Connect lower couplingAlign the lower end of the upper steering shaft with the intermediate shaft, matching the alignment marks made during disassembly. Ensure the coupling is fully engaged with the splines properly meshed. The shafts should slide together with minimal resistance.⚠Misalignment at this connection can cause steering binding or premature wear.
- 11Install coupling boltInsert the pinch bolt through the lower coupling, ensuring it passes through both the coupling and the flat section of the shaft splines. Install the lock nut if equipped. Torque the bolt to the manufacturer's specification for intermediate shaft connections (typically 30-50 Nm, though not listed in provided specs - follow service manual).⚠️The coupling bolt must be fully tightened to specification. An improperly secured coupling can separate during operation, causing complete loss of steering control.
- 12Verify operationBefore reinstalling covers, turn the steering wheel slowly from lock to lock while observing the shaft connections. Verify smooth operation with no binding, clicking, or unusual resistance. Check that all connections remain secure throughout the full range of motion.ℹ️Any binding or noise at this stage indicates improper installation and must be corrected before proceeding.
- 13Reinstall steering column coversPosition the upper steering column cover over the column and secure with the original screws. Install the lower cover in the same manner. Ensure all cover tabs are properly engaged and no gaps exist between covers and the dashboard.Torque specCover Screws12 Nm (9 lb-ft)
Reassembly
- Verify all fasteners are tightened to specification
- Confirm steering wheel position is centered with wheels straight ahead
- Check that all steering column covers are securely fastened with no rattles
Verification
- Start the vehicle and verify no warning lights are illuminated on the instrument cluster
- Turn the steering wheel slowly from lock to lock while stationary, listening for any unusual noises or feeling for binding
- Perform a test drive at low speed in a safe area, verifying smooth steering operation and proper wheel centering
- Check for any clunking or popping noises when turning the wheel, especially during low-speed maneuvers
- Verify the steering wheel returns to center properly after turns
