Solution

1. Preparation

Gather tools and replacement parts.
Ensure the vehicle is on a flat surface and securely lifted with jack stands.
Disconnect the negative battery terminal to prevent electrical shorts.

2. Inspect and Replace Power Steering Fluid

Sub-steps:
1. Locate the power steering reservoir and remove the cap.
2. If fluid is low, top it off with the manufacturer-recommended fluid type.
3. If fluid is contaminated, proceed to drain the old fluid by disconnecting the return line and letting it flow into a container.
4. Reconnect the return line and refill the reservoir with new power steering fluid.

3. Replace Power Steering Pump (if necessary)

Sub-steps:
1. Disconnect the power steering hoses from the pump using a wrench.
2. Remove the mounting bolts securing the power steering pump to the engine.
3. Carefully remove the pump from its bracket.
4. Install the new power steering pump by reversing the removal steps.
5. Reconnect the hoses securely and check for leaks.

4. Check and Replace Steering Angle Sensor (if necessary)

Sub-steps:
1. Disconnect the wiring harness from the steering angle sensor located on the steering column.
2. Remove the bolts securing the sensor and take it out.
3. Install the new steering angle sensor and secure it with bolts.
4. Reconnect the wiring harness and ensure it is secure.

5. Final Checks

Sub-steps:
1. Reconnect the negative battery terminal.
2. Start the vehicle and check for any warning lights on the dashboard.
3. Test the steering assist by turning the steering wheel to ensure smooth operation.
