Solution

1. Preparation

Tools Required: Socket set, torque wrench, flathead screwdriver, Phillips screwdriver, steering wheel puller, OBD-II scanner.
Disconnect the battery to ensure safety while working on electrical components.

2. Remove Steering Wheel

Sub-steps:
1. Remove the airbag module: Use a flathead screwdriver to carefully unclip the airbag from the steering wheel.
2. Disconnect the airbag connector and remove the airbag assembly from the steering wheel.
3. Use a steering wheel puller to remove the steering wheel by loosening the center nut and pulling the wheel off the shaft.

3. Inspect and Replace Components

Sub-steps:
1. Inspect the steering column for worn components such as the universal joints and couplings.
2. If any components are damaged, replace them with OEM parts to ensure compatibility and reliability.
3. Check the steering angle sensor and replace if it is malfunctioning.

4. Reassemble Steering Column

Sub-steps:
1. Place the steering wheel back onto the steering column, ensuring it is properly aligned.
2. Tighten the center nut to the manufacturer's specified torque (typically around 47 Nm).
3. Reconnect the airbag module and ensure all connections are secure.

5. Final Checks

Sub-steps:
1. Reconnect the battery and perform a system check using an OBD-II scanner to clear any previous fault codes.
2. Test drive the vehicle to ensure the steering feels normal and no warning lights are illuminated.
