Disconnect the battery for safety.

2. Inspect and Top Off Power Steering Fluid

Locate the power steering reservoir.
Remove the cap and check the fluid level; top off with manufacturer-recommended fluid if low.

Raise the front of the vehicle using a jack and secure with jack stands.
Remove the front wheels.
Visually inspect the CV boots for tears or grease leakage.
If damaged, replace the CV joints and boots.

4. Check Wheel Bearings

Spin the front wheels by hand; listen for grinding or roughness.
If noise is present, remove the brake calipers and rotors.
Inspect the wheel bearings for wear; replace if necessary.

5. Evaluate Suspension Components

Examine struts for leaks or damage.
Check control arms and bushings for wear.
Replace any worn components as needed, ensuring proper alignment after installation.
