This procedure replaces the steering coupler (intermediate shaft) connecting the steering column to the steering rack on a 2016-2024 Hyundai Tucson with the 2.5L I4 engine.

Warnings

Tools required

Parts

• Steering coupler (intermediate shaft) × 1 — Use OEM specification
• Steering coupler pinch bolt × 2 — Use OEM specification

Preparation

1. Park vehicle on level surface and apply parking brake
2. Place wheel chocks behind rear wheels
3. Turn ignition to ACC position and center the steering wheel exactly
4. Turn ignition off and remove key (steering wheel will lock in center position)
5. Disconnect negative battery terminal and wait 3 minutes for airbag system to discharge
6. Raise front of vehicle with floor jack and support securely on jack stands under frame rails
7. Remove engine splash shield or undertray if equipped for better access

Procedure

1. 1

   Access steering coupler from underneath
   Position yourself under the front of the vehicle with adequate lighting. Locate the steering coupler connecting the steering column shaft to the steering rack input shaft. This is typically just above the steering rack assembly near the firewall.
2. 2

   Mark alignment positions
   Using a white paint marker, make alignment marks across the coupler and both shaft ends (column shaft and rack input shaft). Mark the orientation of the coupler relative to both shafts with multiple reference lines. These marks are critical for proper reassembly alignment.
3. 3

   Remove upper pinch bolt
   Locate the upper pinch bolt securing the coupler to the steering column shaft. Use a socket wrench to remove the pinch bolt completely. Note the bolt orientation and any washers present. The bolt passes through a split clamp design on the coupler.
4. 4

   Remove lower pinch bolt
   Locate the lower pinch bolt securing the coupler to the steering rack input shaft. Remove this bolt completely, noting its orientation. You may need to work from different angles to access this bolt depending on vehicle configuration.
5. 5

   Separate coupler from column shaft
   Spread the upper clamp slightly using a flathead screwdriver if needed. Pull the coupler upward off the steering column shaft splines. If stuck, gently tap the coupler housing (not the shaft) or use a pry bar carefully against the coupler body while pulling.
6. 6

   Remove coupler from rack input shaft
   Pull the coupler assembly downward and off the steering rack input shaft splines. The entire coupler should now be free. Inspect both shafts for damage, wear, or corrosion on the splines.
7. 7

   Prepare new coupler
   Unpack the new steering coupler and inspect it for shipping damage. Verify it matches the original design with the same type of universal joints and clamp configuration. Apply a light coating of multi-purpose grease to the spline areas of both the column shaft and rack input shaft.
8. 8

   Install coupler onto rack input shaft
   Align the new coupler with the steering rack input shaft, matching your alignment marks if the coupler allows for the same orientation. Slide the lower end of the coupler fully onto the rack input shaft splines until it seats completely. Ensure the clamp gap is positioned for bolt installation.
9. 9

   Connect coupler to column shaft
   Align the upper end of the coupler with the steering column shaft, matching your alignment marks. Push the coupler upward onto the column shaft splines until fully seated. Verify both ends are completely engaged on their respective shafts.
10. 10

    Install and torque pinch bolts
    Install new pinch bolts (or reuse if specified by manufacturer) in both the upper and lower clamps. Ensure bolts pass through the clamp gaps correctly. Hand-tighten both bolts first, then torque each to manufacturer specification (typically 27-35 Nm / 20-26 lb-ft, verify in service manual). Check that both ends of the coupler are still fully seated after torquing.
11. 11

    Verify installation alignment
    Double-check that your alignment marks match on both ends of the coupler. Verify there is no binding by gently attempting to rotate the steering shaft (if wheel is not locked) or checking for free movement of the coupler universal joints. Ensure no gaps exist between the coupler and either shaft.

Reassembly

1. Reinstall engine splash shield or undertray if removed
2. Lower vehicle from jack stands
3. Reconnect negative battery terminal
4. Start vehicle and verify no warning lights related to steering or airbag systems

Verification

• Turn steering wheel lock-to-lock slowly while stationary and listen for any clunking, binding, or unusual noises from the coupler area
• Check that steering wheel is still centered when wheels are pointing straight ahead
• Perform a test drive at low speed in a safe area, verifying smooth steering operation with no vibration, play, or binding
• Recheck pinch bolt tightness after test drive
• Verify no steering-related warning lights are illuminated on the dashboard
