Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the vehicle battery to ensure safety while working on electrical components.
Allow the vehicle to sit for a few minutes to cool down if recently driven.

2. Remove Steering Wheel

Use a steering wheel puller to remove the steering wheel:
1. Remove the airbag by unscrewing the retaining screws located at the back of the steering wheel.
2. Disconnect the airbag connector carefully.
3. Unscrew the central nut holding the steering wheel in place with a socket wrench.
4. Use the steering wheel puller to detach the wheel from the column.

3. Inspect and Replace Components

Inspect the steering column assembly:
1. Check for wear or damage in the universal joints and bushings.
2. If any components are worn, replace them with OEM parts.
3. For electronic issues, consider replacing the EPS module if necessary.

4. Reassemble Steering Column

Reinstall the steering wheel:
1. Align the steering wheel to the central position.
2. Secure the central nut to the manufacturer’s specified torque (typically around 45 Nm).
3. Reconnect the airbag connector and reinstall the airbag with the retaining screws.

5. Final Checks

Reconnect the battery.
Clear any fault codes that may have been set during the repair.
Test the steering functionality to ensure proper operation.
