how to fix whining noise in my BMW X3 G01 (2018-2024) when turning

Solution

1. Preparation

• Gather necessary tools and parts.
• Ensure the vehicle is parked on a level surface and secure it with wheel chocks.
• Disconnect the negative terminal of the battery for safety.

2. Check and Fill Power Steering Fluid

• Locate the power steering fluid reservoir.
• If the fluid is low, top it off with the manufacturer-recommended power steering fluid.
• Inspect for contamination; if contaminated, proceed to the next step.

3. Replace Power Steering Fluid

• Drain the existing fluid from the power steering system using a siphon or by removing the return line.
• Refill with new power steering fluid and run the pump briefly to circulate the new fluid.
• Check for leaks and ensure the fluid level is correct.

4. Inspect and Replace Power Steering Pump (if necessary)

• Remove the serpentine belt using a belt tensioner tool.
• Disconnect the power steering lines from the pump.
• Remove the pump mounting bolts and carefully take out the pump.
• Install the new power steering pump and reconnect the lines.
• Reinstall the serpentine belt, ensuring proper tension.

5. Examine and Replace Steering Rack (if necessary)

• If leaks or damage are found on the steering rack, remove it by unbolting the mounting brackets and disconnecting the tie rods.
• Install the new steering rack and ensure proper alignment of tie rods.
• Reconnect all components and check for proper operation.
