Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface, engage the parking brake, and disconnect the battery.

2. Inspect Steering Column

Visually inspect the steering column for any signs of wear or damage.
Check for any loose fittings, bolts, or brackets securing the column.
Ensure that the steering wheel is centered and properly aligned.

3. Check Universal Joints

Locate the universal joints in the steering shaft.
Inspect for signs of wear, corrosion, or binding.
If defective, remove the steering shaft by loosening the clamps and bolts securing the u-joints.

4. Tighten or Replace Loose Components

If loose bolts or connections are found, use a torque wrench to tighten them to manufacturer specifications.
If any components are damaged (such as the universal joints), replace them with new parts. Ensure proper alignment during installation.

Reconnect the steering shaft and ensure all components are secured.
Reconnect the battery and check the steering fluid level, topping off if necessary.
Test the steering by turning the wheel left and right to confirm that the noise is eliminated.
