This procedure covers the removal and replacement of the steering coupler on a 2022 Rivian EDV 500, which connects the steering column to the steering rack.

Warnings

Tools required

Parts

• Steering coupler assembly × 1 — Use OEM specification
• Steering coupler bolt kit × 1 — Use OEM specification
• Lower dash trim clips (if damaged) × 4 — Use OEM specification

Preparation

1. Park vehicle on level surface and engage parking brake
2. Center the steering wheel and verify front wheels are pointed straight ahead
3. Disconnect 12V auxiliary battery and wait 5 minutes for airbag system capacitors to discharge
4. Raise front of vehicle and secure on jack stands
5. Remove front wheels to access steering components from wheel wells if needed
6. Remove lower dash trim panels to access steering column area
7. Document steering wheel position with photo or measurements for reference

Procedure

1. 1

   Mark alignment points
   Using a white paint marker, mark the alignment of the steering column shaft to the coupler, and the coupler to the steering rack input shaft. Make clear reference marks on both sides of each joint to ensure proper reassembly alignment. Take photos for reference.
2. 2

   Access steering coupler from interior
   From inside the vehicle, locate the steering coupler at the base of the steering column near the firewall. Remove any remaining trim panels or insulation that obstruct access to the upper coupler bolt. The coupler is typically accessible through the driver's side footwell area.
3. 3

   Remove upper coupler bolt
   Locate the upper pinch bolt securing the steering coupler to the steering column shaft. Using a socket and ratchet, loosen and remove the upper pinch bolt completely. Note the bolt orientation and any washers or spacers for reinstallation. The bolt may have a locking feature or require specific technique to remove.
4. 4

   Access lower coupler connection
   Move to the underside of the vehicle. Locate the lower portion of the steering coupler where it connects to the steering rack input shaft through the firewall. You may need to remove a protective boot or shield covering the connection point. Ensure you have clear access to the lower pinch bolt.
5. 5

   Remove lower coupler bolt
   Loosen and remove the lower pinch bolt securing the steering coupler to the steering rack input shaft. Apply penetrating lubricant if the bolt shows signs of corrosion. Keep track of any washers or lock features on this bolt as well.
6. 6

   Separate coupler from steering column
   Working from the interior, carefully pull the upper portion of the coupler away from the steering column shaft. If the coupler is stuck, use a small pry bar or flathead screwdriver to gently spread the pinch clamp area. Do not damage the steering column shaft splines or surfaces.
7. 7

   Remove coupler from vehicle
   While supporting the coupler, separate the lower end from the steering rack input shaft. Carefully maneuver the coupler through the firewall opening, rotating as needed to clear any obstructions. Remove the coupler from the vehicle and inspect mounting points on both the column shaft and rack input shaft for damage or wear.
8. 8

   Inspect connection points
   Examine the splines on both the steering column shaft and steering rack input shaft for wear, damage, or deformation. Check for proper spline engagement depth marks. Inspect the firewall boot and grommet for tears or deterioration. Clean any debris from the shaft splines using a wire brush if necessary.
9. 9

   Install new steering coupler
   Position the new steering coupler by inserting the lower end onto the steering rack input shaft first, aligning it through the firewall opening. Ensure the coupler slides fully onto the rack shaft splines and that any alignment features or flats are properly engaged. Verify the coupler reaches the proper depth on the shaft.
10. 10

    Connect coupler to steering column
    From the interior, align the upper portion of the coupler with the steering column shaft, matching your alignment marks. Slide the coupler onto the column shaft splines, ensuring full engagement. The steering wheel should still be centered and wheels pointing straight ahead. Verify proper spline engagement before proceeding.
11. 11

    Install upper pinch bolt
    Install the upper pinch bolt with any washers in their original orientation. Hand-tighten the bolt first to verify proper threading. Torque the upper pinch bolt to manufacturer specification. Note: Since torque specifications are not provided in the database, consult the factory service manual for exact values, typically 22-30 ft-lbs for steering coupler pinch bolts.
12. 12

    Install lower pinch bolt
    Working from underneath the vehicle, install the lower pinch bolt with any washers or lock features in their original positions. Hand-tighten first, then torque to manufacturer specification per the factory service manual. Ensure the bolt fully engages the pinch clamp feature and secures the coupler to the rack shaft.
13. 13

    Verify alignment and engagement
    Check that all alignment marks made during disassembly are properly aligned. Verify there is no excessive play or looseness in the steering coupler connections. Attempt to rotate the steering wheel slightly (without starting vehicle) to confirm smooth engagement without binding or unusual resistance.

Reassembly

1. Reinstall any protective boots, shields, or grommets around the coupler area
2. Reinstall lower dash trim panels and interior components in reverse order of removal
3. Install front wheels and torque lug nuts to specification
4. Lower vehicle from jack stands to ground
5. Reconnect 12V auxiliary battery

Verification

• With vehicle still off, turn steering wheel lock-to-lock and verify smooth operation with no binding, clunking, or unusual noises
• Start vehicle and verify no warning lights appear on instrument cluster related to steering system
• Check that steering wheel is properly centered with wheels pointing straight ahead
• Perform a slow-speed test drive in a safe area, verifying proper steering response and no unusual noises or vibrations
• Turn steering wheel through full range at various speeds to confirm proper operation
• If steering wheel is off-center after replacement, a professional steering alignment may be required
