4. Refill with the manufacturer-recommended power steering fluid to the proper level.

3. Replace Worn Steering Components

Tools Required:
- Socket set
- Torque wrench
- Ball joint separator (if needed)
Instructions:
1. Raise the front of the vehicle using a jack and secure it with jack stands.
2. Remove the wheel to access the steering components.
3. Use a ball joint separator to disconnect the tie rods and ball joints if they are worn.
4. Replace with new components, tightening to manufacturer torque specifications.
5. Reinstall the wheel and lower the vehicle.

4. Inspect and Repair Suspension Components

Tools Required:
- Socket set
- Torque wrench
Instructions:
1. While the vehicle is lifted, visually inspect the suspension for any damaged or worn parts, such as control arms and bushings.
2. If any components are found to be faulty, remove and replace them following manufacturer specifications.
