Solution

1. Preparation

Gather tools: socket set, fluid catch pan, OBD-II scanner, flashlight.
Ensure the vehicle is parked on a flat surface and the engine is turned off.

2. Inspect Power Steering Fluid

Locate the power steering reservoir.
Remove the cap and check the fluid level against the dipstick.
If low, add the recommended power steering fluid as per the owner's manual.

3. Check for Leaks

Visually inspect the power steering pump, hoses, and connections for any signs of fluid leakage.
If leaks are found, tighten connections or replace the faulty components.

4. Inspect CV Joints and Axles

Raise the front of the vehicle using a jack and secure it with jack stands.
Inspect the CV boots for tears or damage.
Rotate the wheels by hand to listen for any unusual noises from the CV joints.

5. Test Steering Rack

With the vehicle still in the air, have an assistant turn the steering wheel while you observe the steering rack.
Look for any excessive movement or noise from the steering rack itself.

6. Clear Error Codes

Using the OBD-II scanner, check for any stored error codes.
Clear any codes found and perform a test drive to see if the issue persists.
