Solution
1. Preparation
  • Gather tools: socket set, torque wrench, fluid catch pan, OBD-II scanner, and safety glasses.
  • Park the vehicle on a level surface and engage the parking brake.
  • Allow the engine to cool before starting work.
2. Inspect Power Steering Fluid
  • Locate the power steering reservoir.
  • Remove the cap and check the fluid level; it should be within the designated range.
  • If low, add the manufacturer-recommended power steering fluid until it reaches the appropriate level.
3. Check for Leaks
  • Inspect power steering hoses and connections for any signs of fluid leaks.
  • If leaks are found, tighten connections or replace damaged hoses as necessary.
  • Use a fluid catch pan to collect any leaking fluid during this process.
4. Examine Steering Rack
  • Raise the vehicle using a jack and secure it with jack stands.
  • Inspect the steering rack for any signs of damage or wear.
  • If damage is identified, remove the steering rack and replace it with a new component.
5. Inspect Suspension Components
  • Check the suspension components, including tie rods and control arms, for wear or damage.
  • Replace any worn or damaged parts to eliminate noise during turning.
6. Reassemble and Test
  • Reattach any components removed during inspection.
  • Tighten all bolts to the manufacturer-specified torque values.
  • Start the engine and turn the steering wheel to ensure the noise has been eliminated.
