Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and set the parking brake.

2. Check Power Steering Fluid

Open the hood and locate the power steering reservoir.
Remove the cap and check the fluid level against the dipstick.
If low, top off with the manufacturer's recommended power steering fluid.
Inspect fluid for contamination (milky appearance or debris). If contaminated, consider flushing the system.

3. Inspect CV Joints

Lift the front of the vehicle using a jack and secure with jack stands.
Rotate the wheels and visually inspect CV joints and boots for cracks or tears.
If damaged, replace the CV joint assembly as necessary.

4. Examine Suspension Components

With the vehicle still lifted, check the ball joints, tie rods, and control arms for any play or excessive wear.
If any component is loose or damaged, replace it with OEM parts.
Ensure to torque all nuts and bolts to manufacturer specifications.

5. Test Wheel Bearings

Spin each front wheel by hand and listen for any grinding or roughness.
If a wheel bearing is suspected to be faulty, replace the bearing/hub assembly.
