1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a level surface and the ignition is off.

2. Inspect and Replace Power Steering Fluid

Sub-steps:
1. Open the hood and locate the power steering fluid reservoir.
2. Check the fluid level using the dipstick or markings on the reservoir.
3. If low, add the manufacturer-recommended power steering fluid until it reaches the correct level.

Sub-steps:
1. Lift the front of the vehicle using a jack and secure it with jack stands.
2. Remove the front wheels to access the tie rods.
3. Use a wrench to loosen the tie rod end nut and disconnect it from the steering knuckle.
4. Inspect the tie rod for wear; replace it if any damage is found.
5. Install the new tie rod and tighten the nut to the manufacturer's torque specifications.

4. Inspect and Replace Ball Joints

Sub-steps:
1. With the front wheels still removed, locate the ball joints on the control arms.
2. Check for any signs of wear, such as cracking or looseness.
3. If necessary, remove the ball joint by loosening the retaining bolts and using a ball joint separator.
4. Install the new ball joint and securely tighten the bolts to the specified torque.

5. Final Assembly
