Solution

1. Preparation

Tools Required: OBD-II scanner, power steering fluid, socket set, torque wrench, fluid catch pan.
Ensure the vehicle is on a level surface and the engine is off before starting repairs.
Disconnect the battery if working on electrical components.

2. Fluid Check and Replacement

Check Fluid Level: Remove the power steering fluid reservoir cap and check fluid level. If low, add the recommended type of power steering fluid.
Replace Fluid: If the fluid is dirty or has debris, drain the old fluid into a catch pan and replace it with new fluid.

3. Inspect and Replace Components

Steering Rack Inspection: If leaks are found, replace the steering rack.
- Remove the underbody cover (if equipped).
- Disconnect the steering shaft and power steering lines.
- Unbolt the steering rack and remove it.
- Install the new rack and reverse the removal steps, ensuring to torque the bolts to manufacturer specifications.

4. Power Steering Pump Inspection

Pump Replacement: If the pump is found to be faulty, replace it.
- Disconnect the power steering lines and electrical connectors.
- Remove the mounting bolts and take out the pump.
- Install the new pump and ensure all connections are secure.

5. Realign Steering Wheel

If the steering wheel is off-center, perform a wheel alignment.
- Use a professional alignment machine to adjust the angles of the wheels according to manufacturer specifications.
