Solution

1. Preparation

Tools Required: OBD-II scanner, socket set, fluid catch pan, torque wrench, and safety gloves.
Gather necessary replacement parts based on diagnostic findings (e.g., power steering fluid, pump, or belt).
Safety Warnings: Disconnect the battery before working on electrical systems. Ensure the vehicle is on a flat surface and the engine is cool.

2. Fluid Replacement

Sub-steps:
1. Locate the power steering fluid reservoir.
2. Use a fluid catch pan to drain old power steering fluid.
3. Replace with the manufacturer-recommended power steering fluid.
4. Start the engine and turn the steering wheel from lock to lock several times to circulate the new fluid.
5. Check fluid levels again and top off if necessary.

3. Power Steering Pump Replacement (if necessary)

Sub-steps:
1. Remove the drive belt from the power steering pump.
2. Disconnect the power steering lines from the pump; be prepared for fluid spillage.
3. Unbolt the power steering pump from its mounting bracket and remove it from the engine bay.
4. Install the new power steering pump, tightening bolts to the manufacturer's specified torque.
5. Reconnect the power steering lines and install the drive belt.

4. Steering Rack Inspection (if needed)

Sub-steps:
1. Lift the vehicle securely using jack stands and remove the front wheels.
2. Inspect the steering rack for visible damage or leaks.
3. If damage is found, detach the steering rack from the subframe and disconnect the tie rods.
4. Install the new steering rack, ensuring all connections are tight and secure.
