Replace the steering shaft coupler connecting the steering column to the steering gear input shaft, restoring proper steering connection and eliminating play or binding.
Warnings
⚠️Never turn the steering wheel with the coupler disconnected or the clockspring may be damaged, causing airbag system failure
⚠Mark all alignment positions before disassembly to maintain proper steering wheel center position
⚠Support vehicle securely on jack stands—working under a vehicle supported only by a jack is extremely dangerous

Parts
- Steering shaft coupler assembly × 1 — Use OEM specification
- Steering coupler pinch bolts × 2 — Use OEM specification
Preparation
- Park vehicle on level surface and set parking brake
- Turn ignition off and remove key
- Center the steering wheel and lock it in position using a steering wheel lock or strap
- Raise front of vehicle and support securely on jack stands
- Remove front skid plate if equipped (retains with multiple fasteners)
- Disconnect negative battery cable and wait 10 minutes for airbag system to discharge
Procedure
- 1Access steering coupler from belowPosition yourself under the vehicle with adequate lighting. Locate the steering shaft coupler between the steering column shaft and steering gear input shaft, above the front crossmember. The coupler is a U-joint style connection with pinch bolts at both ends.
- 2Mark alignment positionsUsing white paint or marker, mark the relationship between the steering column shaft and coupler, and between the coupler and steering gear input shaft. Make clear index marks on all mating surfaces to ensure proper reassembly alignment. This is critical for maintaining steering wheel center position.⚠Accurate alignment marks prevent steering wheel misalignment after reassembly
- 3Remove upper pinch boltLocate the upper pinch bolt securing the coupler to the steering column shaft. Loosen and remove the pinch bolt completely. Note the orientation of the bolt for reassembly. The bolt passes through the coupler yoke and clamps onto the splined shaft.
- 4Remove lower pinch boltLocate the lower pinch bolt securing the coupler to the steering gear input shaft. Loosen and remove the pinch bolt completely. You may need to rotate the coupler slightly (without turning the steering wheel) to access the bolt head. Note bolt orientation.
- 5Separate and remove couplerCarefully slide the coupler upward off the steering gear input shaft first, then downward off the steering column shaft. The coupler may be tight on the splines—use gentle rocking motion if needed. Do not use excessive force or pry directly on shafts. Remove coupler from vehicle.⚠Do not allow steering column shaft or steering gear shaft to rotate during removal
- 6Inspect shafts and splinesInspect both the steering column shaft and steering gear input shaft splines for wear, damage, or corrosion. Check for proper engagement depth marks on shafts. Clean splines with wire brush if corrosion is present. Verify steering wheel has not moved from center position.
- 7Install new couplerPosition new coupler assembly. Slide upper end onto steering column shaft first, aligning the yoke with your alignment marks. Ensure proper spline engagement (shaft should slide in smoothly). Then slide lower end onto steering gear input shaft, again aligning with marks. Verify both ends are fully seated on splines.⚠Ensure alignment marks match exactly to prevent steering wheel misalignment
- 8Install upper pinch boltInstall new upper pinch bolt through coupler yoke and tighten to secure steering column shaft connection. Ensure bolt passes through both the yoke and the shaft groove/flat. Torque bolt to 31 Nm (23 lb-ft). Verify coupler cannot slide on upper shaft.Torque specMounting Bolts31 Nm (23 lb-ft)
- 9Install lower pinch boltInstall new lower pinch bolt through coupler yoke and tighten to secure steering gear input shaft connection. Ensure bolt passes through both the yoke and the shaft groove/flat. Torque bolt to 31 Nm (23 lb-ft). Verify coupler cannot slide on lower shaft.Torque specMounting Bolts31 Nm (23 lb-ft)
- 10Verify installationVisually confirm both pinch bolts are properly torqued and aligned. Check that alignment marks are properly matched. Verify there is no excessive play in the coupler connection. Ensure coupler does not contact any surrounding components through full range of motion.
Reassembly
- Reinstall front skid plate if equipped
- Reconnect negative battery cable
- Remove steering wheel lock
- Lower vehicle to ground
Verification
- Start engine and verify power steering operation
- Turn steering wheel lock-to-lock slowly and verify smooth operation with no binding or unusual noises
- Verify steering wheel is centered when wheels are pointed straight ahead
- Test drive vehicle at low speed in safe area to confirm proper steering function and center position
- Check for any play or looseness in steering by turning wheel slightly with vehicle stationary
- Scan for airbag or steering-related diagnostic codes with scan tool if available
