Solution

1. Preparation

Tools Required: Jack and jack stands, wheel chocks, OBD-II scanner, torque wrench, socket set, and safety gloves.
Ensure the vehicle is parked on a level surface and the parking brake is engaged. Disconnect the battery if working on electrical components.

2. Check Power Steering Fluid

Locate the power steering fluid reservoir.
Remove the cap and check the fluid level; it should be between the minimum and maximum marks.
If low, top off with the recommended power steering fluid type (consult the owner's manual).

3. Inspect Steering and Suspension Components

Lift the vehicle using a jack and secure it with jack stands.
Visually inspect the steering linkage (tie rods, steering rack) for damage or excessive play.
Check the suspension components (control arms, bushings) for signs of wear or damage.

4. Inspect Wheel Bearings and CV Joints

Spin each front wheel by hand to check for grinding noise or roughness, indicating a bad wheel bearing.
Inspect the CV joints for torn boots, which can lead to contamination and failure; if damaged, replace the CV joint assembly.

5. Reassemble and Check

Reinstall any components that were removed or loosened during inspection.
Torque all bolts to the manufacturer's specifications.
Reconnect the battery if it was disconnected.
