Solution

1. Preparation

Gather tools and parts required for the repair.
Disconnect the battery to avoid electrical issues while working on the steering column.
Ensure the vehicle is on a flat surface and secure it with wheel chocks.

2. Remove Steering Wheel

Tools Required: Steering wheel puller, socket set, torque wrench.
Loosen the steering wheel retaining nut using the socket set.
Use the steering wheel puller to carefully remove the steering wheel.
Disconnect any electrical connectors for the airbag and steering controls.

3. Access Steering Column

Remove the plastic covers from the steering column by unscrewing the retaining screws.
Inspect the column for loose bolts or components that may contribute to noise.

4. Inspect and Replace Components

Check the upper and lower steering column bearings for wear. Replace if necessary.
Inspect the universal joint (U-joint) for any signs of damage. If damaged, replace it with a new part.
Lubricate any moving parts with high-quality grease to reduce friction and noise.

5. Reassemble Steering Column

Reinstall the steering column covers and secure with screws.
Reattach the steering wheel and ensure it is properly aligned.
Tighten the steering wheel retaining nut to the manufacturer’s specified torque value (typically around 35 Nm).

6. Reconnect Battery and Test

Reconnect the battery and clear any error codes with the OBD-II scanner.
Test drive the vehicle to ensure the noise has been resolved and that steering feels smooth.
