Solution

1. Preparation

Gather tools: jack, jack stands, lug wrench, torque wrench, and flashlight.
Ensure the vehicle is on a flat surface, engage the parking brake, and disconnect the battery.

2. Inspect and Replace Tires (if necessary)

Sub-steps:
- Remove the wheel using the lug wrench.
- Inspect the tire for damage or uneven wear; replace if necessary.
- Reinstall the wheel and torque the lug nuts to the manufacturer's specification (typically 80-100 ft-lbs).

- Check the fluid level; if low, add the manufacturer-recommended fluid until it reaches the correct level.
- Inspect for leaks around the reservoir and lines.

4. Inspect and Replace Worn Steering Components

Sub-steps:
- Visually inspect tie rods and ball joints for signs of wear.
- If wear is detected, remove and replace the worn components.
- Torque new components to specified values (consult service manual for exact specs).

5. Examine and Replace Brake Components (if necessary)

Sub-steps:
- Remove the wheel to access the brake assembly.
- Inspect brake pads for wear; replace if thickness is below 3mm.
- Check rotors for scoring or damage; replace if necessary.
- Reinstall everything and torque to manufacturer specifications.

6. Inspect and Replace CV Joints (if necessary)

Sub-steps:
