3. If the fluid is dirty or contaminated, drain the old fluid by loosening the return line and allowing it to drain into a container.
4. Refill with new power steering fluid and run the engine to cycle the fluid through the system.

3. Replace Damaged Components

Tools Required: Socket set, torque wrench, pry bar
Procedure:
1. If any tie rods or ball joints are found to be damaged during inspection, replace them.
2. Remove the wheel to access the suspension components.
3. Use a pry bar to disconnect the affected tie rod or ball joint.
4. Install the new component, ensuring to torque to manufacturer specifications.
5. Reinstall the wheel and lower the vehicle.

4. Steering Rack Replacement (if necessary)

Tools Required: Wrench set, jack stands, steering wheel puller
Procedure:
1. If the steering rack is damaged, remove it by disconnecting all linkages and mounting bolts.
2. Install the new steering rack in the reverse order, ensuring all connections are tight.
