Solution

1. Preparation

Gather tools: OBD-II scanner, socket set, torque wrench, power steering fluid, fluid extraction tool, pressure gauge.
Park the vehicle on a level surface and ensure the engine is off and cool.
Disconnect the battery to prevent any electrical issues during the repair.

2. Fluid Check and Replacement

Inspect Fluid Level
- Open the power steering fluid reservoir cap and check the fluid level. If low, fill with the manufacturer-specified power steering fluid.
Drain Old Fluid
- Use a fluid extraction tool to remove old power steering fluid from the reservoir.
Flush System (if necessary)
- Disconnect the return hose from the power steering pump and place it in a container. Fill the reservoir with fresh fluid and turn the steering wheel from lock to lock to flush out old fluid until clean fluid emerges from the return hose. Reconnect the hose.
Refill Reservoir
- Fill the reservoir to the recommended level with new power steering fluid.

3. Inspect and Replace Power Steering Pump (if needed)

Remove the Pump
- Disconnect the power steering pump belt using a socket set. Remove mounting bolts and disconnect the fluid lines.
Inspect the Pump
- Check for signs of wear, leaks, or noise when manually turning the pump shaft.
Install New Pump (if replacement is necessary)
- Position the new power steering pump, tighten mounting bolts to manufacturer torque specifications, and reconnect fluid lines.
Reinstall the Belt
- Reinstall the power steering pump belt and adjust the tension as required.

4. Final Checks

Reconnect Battery
- Once all repairs are completed, reconnect the battery.
Test System
- Start the engine and turn the steering wheel to check for noise. Ensure the fluid level is still at the recommended level.
