Center Link/Drag Link

This procedure covers the removal and replacement of the steering center link (rack and pinion assembly) on the 2016-2021 Honda Civic 1.5L Turbo, including tie rod disconnection and steering system realignment.

Warnings

Tools required

Parts

• Steering rack and pinion assembly × 1 — Use OEM specification
• Tie rod ends (inner) × 2 — 53540-TBA-A01 or equivalent
• Cotter pins × 2 — 2.5mm x 25mm
• Steering rack mounting bushings × 2 — Use OEM specification
• Tie rod boot clamps × 4 — Use OEM specification

Preparation

1. Park vehicle on level surface and engage parking brake
2. Turn steering wheel to center position and lock steering wheel using a steering wheel lock or remove ignition key
3. Mark the steering wheel position relative to the column with paint or tape for reference
4. Loosen front wheel lug nuts while vehicle is on ground
5. Raise front of vehicle and support securely on jack stands at manufacturer-specified jacking points
6. Remove both front wheels completely
7. Mark the position and thread count of both outer tie rod ends before removal to preserve approximate alignment

Procedure

1. 1

   Remove front wheel well splash shields
   Remove the plastic splash shields from both front wheel wells to access the steering components. Remove the cover screws securing the shields and set aside for reinstallation.
   Torque spec

   Cover Screws10 Nm (8 lb-ft)
2. 2

   Disconnect outer tie rod ends
   Remove the cotter pins from both outer tie rod end castle nuts and discard. Using a 17mm socket, loosen but do not fully remove the tie rod nuts. Strike the steering knuckle boss with a hammer near the tie rod taper to shock the taper loose, then remove the nut completely. Use a ball joint separator or pickle fork if necessary to separate the tie rod from the knuckle. Support the tie rod to prevent damage to the boots.
   ⚠Do not strike the tie rod end itself or damage to the ball joint may occur. Strike only the knuckle boss area.
   Torque spec

   Castle Nuts55 Nm (41 lb-ft)
3. 3

   Mark and remove inner tie rods from rack
   Mark the exact position of the inner tie rod threads where they enter the steering rack ends using a paint pen or wire. Count and record the number of visible threads. Loosen the tie rod boot clamps. Using a 17mm wrench on the flats of the inner tie rod, unthread both inner tie rods from the steering rack. Keep left and right sides identified.
4. 4

   Remove steering rack mounting hardware
   Locate the two steering rack mounting bolts that secure the rack to the subframe. These are accessible from underneath the vehicle. Using a 14mm socket, remove both rack mounting bolts completely. Support the rack with one hand while removing the second bolt to prevent the rack from dropping.
   ⚠The steering rack may shift or drop when the second mounting bolt is removed. Ensure adequate support.
   Torque spec

   Mounting Bolts26 Nm (19 lb-ft)
5. 5

   Disconnect steering column coupler
   Access the steering column intermediate shaft coupler from inside the vehicle at the firewall or from underneath depending on access. Remove the pinch bolt securing the steering shaft to the rack input shaft. Mark the alignment of the coupler and shaft before separation. Carefully slide the coupler off the rack input shaft.
   ⚠️Do not allow the steering column to rotate or extend beyond its normal range once disconnected, as this may damage the clock spring.
6. 6

   Remove power steering connector
   Disconnect the electrical connector for the electric power steering motor located on the steering rack assembly. Press the locking tab and pull the connector straight off. Ensure no strain is placed on the wiring harness.
7. 7

   Remove steering rack assembly
   With all connections disconnected, carefully maneuver the steering rack assembly out from the driver's side of the vehicle. You may need to rotate or angle the rack to clear subframe members and suspension components. Work slowly to avoid damaging brake lines, wiring, or suspension components.
8. 8

   Transfer components to new rack
   If not included with the new rack assembly, transfer the inner tie rods to the new rack. Thread them in to the exact position marked during removal, matching thread count and paint marks. Install new tie rod boot clamps. Inspect and replace mounting bushings if worn.

   Tie Rod Nut52 Nm (38 lb-ft)
9. 9

   Install new steering rack assembly
   Position the new steering rack into the vehicle from the driver's side, reversing the removal path. Align the rack mounting holes with the subframe mounting points. Ensure the rack input shaft is accessible for steering column connection and positioned correctly for center steering position.
10. 10

    Install rack mounting bolts
    Insert both steering rack mounting bolts through the rack brackets and into the subframe. Hand-tighten both bolts first to ensure proper alignment, then torque both bolts to specification using a torque wrench.
    ℹ️Ensure mounting bushings are properly seated before torquing bolts.
    Torque spec

    Rack Bolts97 Nm (71 lb-ft)
11. 11

    Reconnect steering column coupler
    Align the steering column intermediate shaft coupler with the rack input shaft, matching the alignment marks made during removal. Slide the coupler fully onto the input shaft splines. Install the pinch bolt and torque to specification per service manual (not provided in torque list - use Honda specification).
12. 12

    Reconnect power steering connector
    Connect the electric power steering motor electrical connector to the rack assembly. Ensure the connector locks securely with an audible click. Verify the wiring harness is routed properly and not pinched or strained.
13. 13

    Reconnect outer tie rod ends
    Insert the outer tie rod end tapers into the steering knuckles on both sides. Install the castle nuts and tighten to specification using a torque wrench. Continue tightening to the next cotter pin slot if necessary (do not loosen to align). Install new cotter pins and bend tabs to secure.
    ⚠Always tighten castle nuts to the next cotter pin slot; never back off to align the slot.
    Torque spec

    Castle Nuts55 Nm (41 lb-ft)
14. 14

    Reinstall splash shields and wheels
    Reinstall the front wheel well splash shields using the cover screws and torque to specification. Install both front wheels, threading lug nuts by hand first. Lower the vehicle until wheels contact the ground but vehicle weight is not fully on wheels. Torque lug nuts in a star pattern to specification. Fully lower vehicle and remove jack stands.
    Torque spec

    Cover Screws10 Nm (8 lb-ft)

    Wheel Lug Nuts129 Nm (95 lb-ft)

Reassembly

1. Verify all electrical connectors are securely fastened
2. Verify steering wheel is still locked or centered and has not rotated during the procedure
3. Check that all fasteners have been torqued to specification
4. Verify no tools or parts have been left in the engine bay or underneath the vehicle

Verification

• Start the engine and verify the electric power steering system initializes without warning lights
• Turn the steering wheel lock-to-lock slowly while stationary to verify smooth operation and no binding or unusual noises
• Verify the steering wheel is still centered when wheels are pointed straight ahead (minor adjustment acceptable)
• Test drive the vehicle at low speed in a safe area to verify proper steering response
• Schedule a four-wheel alignment immediately, as steering geometry has been disturbed
• After alignment, verify no steering pulling and that steering wheel is centered during straight-line driving
