3. Inspect Steering Column Components

Visually inspect the entire steering column and shaft for any signs of damage or wear.
Check the universal joint and bearings for excessive play or binding.
If damaged components are found, proceed to replace them.

4. Lubricate and Reassemble

Apply appropriate grease to the universal joints and bearings to ensure smooth operation.
Reinstall the steering wheel by aligning it with the column and tightening the central nut to the manufacturer's torque specification (usually around 30 Nm).
