Solution

1. Preparation

Tools Required: OBD-II scanner, fluid catch pan, socket set, torque wrench.
Ensure the vehicle is on a level surface and the engine is off.
Disconnect the battery to prevent electrical shorts.

2. Inspect and Top Off Power Steering Fluid

Locate the power steering fluid reservoir.
Remove the cap and check the fluid level; it should be between the minimum and maximum marks.
If low, add the appropriate type of power steering fluid as specified in the owner's manual.
Replace the cap securely.

3. Address Leaks

If fluid is leaking, identify the source (pump, hoses, or steering rack).
For a leaking power steering pump, remove it by:
- Disconnecting the fluid lines with a wrench.
- Unbolting the pump from its mounting bracket.
Replace with a new power steering pump and reconnect fluid lines. Tighten to manufacturer specifications.

4. Repair or Replace Steering Components

If the tie rods or steering rack show signs of wear:
- Lift the vehicle and remove the front wheels.
- Unbolt the tie rod ends from the steering knuckle and remove them.
- If necessary, remove the steering rack by unbolting it from the subframe.
- Install the new components, ensuring proper alignment and torque specifications.

5. Reconnect Battery and Test

Reconnect the battery and start the vehicle.
Check for any leaks in the power steering system.
Turn the steering wheel from lock to lock to bleed any air from the system.
