Replace the steering shaft coupler connecting the steering column to the steering rack input shaft to eliminate play or binding in the steering system.

Warnings

Tools required

Parts

• Steering shaft coupler × 1 — 45260-06100 or equivalent
• Coupler bolt(s) × 2 — Use OEM specification

Preparation

1. Park vehicle on level surface and engage parking brake
2. Turn ignition to ACC position and center the steering wheel precisely
3. Turn ignition off and remove key
4. Lock the steering wheel using a steering wheel holder or insert locking pin through column (prevents clockspring damage)
5. Raise front of vehicle and support securely on jack stands
6. Remove driver side lower dashboard trim panel to access steering column
7. Remove steering column cover screws and upper/lower covers

Procedure

1. 1

   Remove steering column covers
   Remove the screws securing the upper and lower steering column covers. Carefully separate the covers and set aside. This provides access to the upper portion of the steering coupler.
   Torque spec

   Cover Screws11 Nm (8 lb-ft)
2. 2

   Mark alignment positions
   Using a marker or paint pen, make alignment marks across the steering shaft, coupler, and steering rack input shaft. Mark the relationship between the upper steering shaft and coupler, and the coupler to the lower steering rack input shaft. These marks are critical for proper reassembly alignment.
   ⚠Accurate alignment marks prevent steering wheel off-center condition after reassembly.
3. 3

   Access coupler from below
   From underneath the vehicle, locate the steering coupler connection at the firewall where the steering column enters the engine bay. The coupler connects the steering column shaft to the steering rack input shaft. Use a flashlight to clearly identify the coupler and mounting bolts.
   ℹ️The coupler may have one or two pinch bolts depending on design. Verify configuration before proceeding.
4. 4

   Remove upper coupler bolt
   Remove the upper pinch bolt securing the coupler to the steering column shaft. This bolt typically faces upward and may require a universal joint or swivel socket for access. Note the bolt orientation for reinstallation.
   Torque spec

   Mounting Bolts27 Nm (20 lb-ft)
5. 5

   Remove lower coupler bolt
   Remove the lower pinch bolt securing the coupler to the steering rack input shaft. Access may be limited and require working from different angles. Support the coupler as you remove the final bolt.
   Torque spec

   Mounting Bolts27 Nm (20 lb-ft)
6. 6

   Remove steering coupler
   Carefully slide the coupler off both shafts. The coupler may be tight due to the pinch mechanism. If necessary, use a flat blade screwdriver to carefully spread the pinch slot slightly while pulling the coupler off. Do not damage the steering shaft splines or rack input shaft.
   ⚠Do not rotate either shaft once the coupler is removed. Verify the steering wheel lock is still engaged.
7. 7

   Inspect shafts and splines
   Inspect both the steering column shaft and rack input shaft for damage, wear, or corrosion on the splines. Check for any play in the steering column bearings. Clean any corrosion from the shaft splines using a wire brush. Apply a light coating of molybdenum grease to the splines.
   ℹ️If shaft splines are damaged or worn, additional components may need replacement.
8. 8

   Install new steering coupler
   Position the new coupler with the pinch bolt slots aligned to your marks. Slide the coupler onto both shafts simultaneously, aligning with your reference marks. Ensure the coupler fully seats onto both shafts with splines properly engaged. The pinch bolt holes should align with the flat spots or grooves on each shaft.
   ⚠Verify that alignment marks match before tightening bolts. Misalignment will result in off-center steering wheel.
9. 9

   Install and torque coupler bolts
   Install both pinch bolts with the bolt heads positioned as original. Torque the upper and lower coupler mounting bolts to specification. Ensure the pinch slots close properly and the bolts are seated through both sides of the coupler yoke.
   ⚠Do not overtighten pinch bolts as this may crack the coupler. Use accurate torque wrench.

   Mounting Bolts27 Nm (20 lb-ft)
10. 10

    Verify coupler installation
    Check that the coupler is fully seated on both shafts with no gaps. Verify alignment marks still match. Attempt to move the coupler by hand to confirm it is securely fastened with no play between shafts. The steering column and rack should now move as one unit.
    ℹ️Any play or movement indicates improper installation or worn components.

Reassembly

1. Reinstall steering column upper and lower covers, torquing cover screws to specification
2. Reinstall driver side lower dashboard trim panel
3. Remove steering wheel lock or holding device
4. Lower vehicle from jack stands
5. Start engine and verify power steering operation (if equipped)

Verification

• With engine running, turn steering wheel lock-to-lock and verify smooth operation with no binding, clunking, or unusual noises
• Verify steering wheel is centered when wheels are pointed straight ahead
• Check for any play in the steering system by having an assistant rock the steering wheel while you observe the coupler connection
• Test drive vehicle at low speed in a safe area to confirm proper steering feel and wheel centering
• Verify no abnormal noises from the coupler area during turning
