Solution

1. Preparation

Gather tools: OBD-II scanner, fluid container, socket set, torque wrench, and safety gloves.
Park the vehicle on a level surface and engage the parking brake.
Disconnect the negative battery terminal for safety.

2. Inspect Power Steering Fluid

Locate the power steering fluid reservoir.
Remove the cap and check the fluid level; add manufacturer's recommended fluid if low.
Inspect the fluid for contamination or a burnt smell, indicating potential issues.

3. Check for Leaks

Visually inspect the power steering hoses and connections for any signs of leaks.
Clean the area around the power steering pump and hoses, then observe for new leaks when the vehicle is running.

4. Test Power Steering Pump

With the vehicle running, turn the steering wheel fully left and right to listen for changes in the noise from the pump.
If the noise persists, remove the pump for further inspection.
Replace the pump if it shows signs of wear or if noise continues after checking fluid levels.

5. Inspect Steering Linkage

Raise the front of the vehicle securely on jack stands.
Visually inspect the steering linkage components (tie rods, rack and pinion) for any damage or excessive play.
Replace any worn components as necessary using the appropriate torque specifications.

6. Check CV Joints and Wheel Bearings

Inspect the CV joints for torn boots or grease leakage.
Spin the wheels by hand and listen for any grinding noises that indicate bearing wear.
Replace any damaged CV joints or wheel bearings according to manufacturer specifications.
