Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface with the engine off.
Disconnect the battery to prevent electrical issues while working on the vehicle.

2. Inspect and Replace Power Steering Components

Power Steering Fluid Inspection
- Remove the power steering fluid reservoir cap.
- Check the fluid level; if low, top off with the appropriate fluid (check owner's manual for specifications).
- If the fluid is dark or contaminated, drain and replace it.
Check for Leaks
- Inspect all hoses and connections for signs of leaks.
- Tighten any loose connections or replace damaged hoses.

3. Inspect and Replace CV Joints

Remove the Wheel
- Loosen the lug nuts, then lift the vehicle using a jack and secure it with jack stands.
- Remove the lug nuts and take off the wheel.
Inspect CV Joints
- Check the outer CV joint for tears in the boot and ensure it is greased properly.
- If damaged, remove the axle nut and disconnect the CV axle from the hub. Replace with a new CV axle if necessary.

4. Inspect and Replace Suspension Components

Visual Inspection of Suspension
- Check struts, bushings, and control arms for wear.
- Use a ball joint separator to detach the components if any are worn and need replacement.
Replace Worn Components
- Remove the old component and install the new one, ensuring to torque bolts to manufacturer specifications (refer to service manual for torque values).

5. Reassemble and Lower Vehicle

Reinstall Wheel
- Place the wheel back on the hub and hand-tighten the lug nuts.
- Lower the vehicle and fully torque the lug nuts in a crisscross pattern.

6. Final Checks

Reconnect the battery.
Start the vehicle and check for any noise while turning the steering wheel.
