Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a level surface and secured with wheel chocks.
Disconnect the battery to prevent electrical shock and accidental deployment of the airbag.

2. Remove Steering Wheel

Tools Required: Steering wheel puller, socket set
Remove the airbag module by carefully prying it off the steering wheel.
Disconnect the airbag connectors.
Use a socket to remove the central bolt securing the steering wheel, then use a steering wheel puller to carefully detach it.

3. Inspect Steering Column Components

Visually inspect the steering column for signs of wear or damage.
Check the steering column bearing for play or wear.
If any components are damaged, note them for replacement.

4. Replace Faulty Components

If the steering column bearing or any other components are found defective:
- Remove the damaged part by following the manufacturer’s guidelines for disassembly.
- Install the new component, ensuring it is securely fastened according to torque specifications.

5. Reassemble Steering Wheel and Components

Reattach the steering wheel, aligning it properly.
Reconnect the airbag connectors and snap the airbag module back into place.
Reconnect the battery and ensure all tools are removed from the vehicle.
