Solution

1. Preparation

Gather tools and parts required for the job.
Ensure the vehicle is parked on a level surface and the ignition is turned off.
Disconnect the battery to avoid any electrical issues.

2. Remove the Steering Wheel

Remove the airbag (if equipped) by unscrewing the retaining screws located on the back of the steering wheel.
Disconnect the airbag connector and set the airbag aside safely.
Use a steering wheel puller to remove the steering wheel from the column.

3. Remove the Steering Column Covers

Unscrew the retaining screws and gently detach the upper and lower steering column covers to access the steering shaft.

4. Inspect and Replace the Steering Shaft

Inspect the steering shaft for any wear, play, or damaged universal joints.
If the shaft is faulty, remove it by unscrewing the bolts that attach it to the steering gear and column.
Install the new steering shaft by reversing the removal steps and ensuring it is properly aligned.

5. Reassemble Components

Reattach the steering column covers and ensure all screws are tightened to the manufacturer's specifications.
Reinstall the steering wheel and reconnect the airbag connector, securing the airbag back into place.

6. Final Checks

Reconnect the battery and perform a steering wheel centering check.
Ensure there are no loose connections and that all components are securely fastened.
