Solution

1. Preparation

Gather tools: jack, jack stands, socket set, torque wrench, and a multimeter.
Park the vehicle on level ground and engage the parking brake.

2. Check Power Steering System

Sub-steps:
1. Open the hood and locate the power steering reservoir.
2. Remove the cap and check the fluid level; add the recommended fluid if low.
3. Inspect for any signs of leaks around hoses and connections.

3. Inspect CV Joints and Boots

Sub-steps:
1. Safely lift the front of the vehicle using a jack and secure with jack stands.
2. Remove the front wheels using a socket wrench.
3. Inspect the CV joints for cracks or tears in the rubber boots; replace if damaged.
4. If the CV joint is making noise, replace the entire axle assembly.

4. Check Wheel Bearings

Sub-steps:
1. Spin the front wheels by hand to listen for any grinding noises.
2. Grab the top and bottom of the tire and try to rock it back and forth; there should be minimal play.
3. If there is excessive play or noise, remove the wheel hub assembly and replace the wheel bearings.

5. Inspect Suspension Components

Sub-steps:
1. Inspect strut mounts for wear or damage.
2. Check for any loose or broken suspension components, including sway bar links and control arms.
3. Replace any worn parts as necessary.
