This procedure covers removal and replacement of the upper steering shaft on a 2014-2019 Toyota Corolla with 1.8L I4 engine, connecting the steering column to the lower intermediate shaft.

Warnings

Tools required

Parts

• Upper steering shaft assembly × 1 — Use OEM specification
• Lower pinch bolt (if reusable bolt is damaged) × 1 — Use OEM specification

Preparation

1. Park vehicle on level ground and engage parking brake
2. Turn steering wheel to center position with wheels straight ahead
3. Disconnect negative battery terminal and wait 90 seconds minimum
4. Remove driver's side lower dashboard trim panel and knee bolster for access to steering column
5. Install steering wheel holder or insert locking pin to prevent wheel rotation during service

Procedure

1. 1

   Mark steering shaft alignment
   Before loosening any fasteners, use white paint marker to mark the alignment position between the upper steering shaft and lower intermediate shaft at the joint. This ensures proper reassembly and prevents steering angle sensor issues.
2. 2

   Access upper steering column
   From inside the vehicle, locate the upper steering shaft where it connects to the steering column under the dashboard. You may need to remove additional trim panels or the steering column covers for better access. Remove any electrical connectors that may interfere with shaft removal.
3. 3

   Remove upper shaft mounting fasteners
   Locate and remove the mounting bolts or nuts securing the upper steering shaft to the steering column bracket. Support the shaft while removing the last fastener to prevent it from dropping.

4. 4

   Access lower shaft connection
   Working from under the dashboard or from the engine bay (depending on access), locate the pinch bolt connection between the upper steering shaft and lower intermediate shaft at the firewall area. Clean any dirt or debris from the bolt area.
5. 5

   Remove lower pinch bolt
   Remove the pinch bolt that clamps the upper steering shaft to the lower intermediate shaft. Note the orientation of the bolt and clamp. Ensure your alignment marks from Step 1 are still visible before separating the shafts.
   ⚠Do not strike or force the shafts apart. If stuck, apply penetrating oil and allow to soak before carefully separating.
6. 6

   Separate and remove upper shaft
   Carefully separate the upper steering shaft from the lower intermediate shaft, ensuring not to rotate either component. Remove the upper steering shaft assembly from the vehicle, maneuvering it through the dashboard area. Note the routing and orientation for installation.
7. 7

   Inspect components
   Inspect the lower intermediate shaft splines for wear, damage, or rust. Check the steering column mounting bracket and bushings for damage. Clean the splines on the lower shaft with a wire brush if installing the old upper shaft.
8. 8

   Install new upper steering shaft
   Route the new upper steering shaft into position, ensuring proper orientation matches the original installation. Align the splines with the lower intermediate shaft using your alignment marks as reference. Do not force the connection; splines should engage smoothly when properly aligned.
9. 9

   Install lower pinch bolt
   With shafts fully engaged and alignment marks matched, install the pinch bolt through the clamp. Ensure the bolt passes through both the clamp and the shaft groove correctly. Tighten to specification using a torque wrench.
   ⚠The pinch bolt must be torqued correctly and seated fully in the shaft groove. Verify proper engagement before final tightening.

    Secure upper shaft to column
    Align the upper steering shaft to the steering column mounting bracket. Install all mounting bolts or nuts and torque to specification in a cross pattern if multiple fasteners are present.

    Verify installation and remove steering lock
    Check that all fasteners are tight and properly torqued. Verify alignment marks are still matched. Remove the steering wheel holder or locking pin. Reconnect any electrical connectors that were disconnected.
12. 12

    Reinstall interior trim
    Reinstall the steering column covers, knee bolster, and lower dashboard trim panels. Ensure all clips and fasteners are properly seated. Reconnect the negative battery terminal.

Reassembly

1. Torque all fasteners to specification as noted in the procedure steps
2. Ensure alignment marks between upper and lower steering shafts are properly matched
3. Verify steering wheel is centered and steering wheel holder has been removed before starting vehicle
4. All trim panels and covers must be properly reinstalled and secured

Verification

• Start the engine and verify no warning lights remain illuminated on the dashboard
• Turn steering wheel lock-to-lock while stationary and verify smooth operation with no binding or unusual noises
• Perform a slow-speed test drive in a safe area and verify steering response is normal and centered
• Check that horn and steering wheel controls function properly
• Verify no squeaks, clunks, or abnormal noises from the steering column during operation
