my Toyota Highlander XU70 (2020-Present) has a weird noise when turning

Solution

1. Preparation

• Gather tools and materials:
  • Jack and jack stands
  • Socket set
  • Torque wrench
  • Power steering fluid (as specified by manufacturer)
  • Lubricant (if applicable)
• Ensure the vehicle is on a flat surface and the parking brake is engaged.

2. Inspect Power Steering System

• Check Fluid Level:
  • Open the hood and locate the power steering reservoir.
  • Remove the cap and check the fluid level; add fluid if necessary.
• Look for Leaks:
  • Inspect hoses and connections for any signs of fluid leaks.

3. Examine Suspension Components

• Lift Vehicle:
  • Use a jack to lift the front of the vehicle and secure with jack stands.
• Inspect Tie Rods and Ball Joints:
  • Visually examine tie rods and ball joints for any play or damage.
  • Use a pry bar to check for excessive movement in these components.
• Tighten Loose Components:
  • If any components appear loose, tighten them to the manufacturer's torque specifications.

4. Check Wheel Bearings

• Inspect Bearings:
  • Spin each front wheel and listen for abnormal noises.
  • If noise is detected, remove the wheel and inspect the bearings for wear.
• Replace Bearings if Necessary:
  • If bearings are worn, remove the hub assembly, replace bearings, and reassemble.

5. Reassemble and Test Drive

• Reinstall Wheels:
  • Torque wheel bolts to manufacturer specifications.
• Lower Vehicle:
  • Carefully remove jack stands and lower the vehicle.
• Test Drive:
  • Drive the vehicle in a safe area to check if the noise persists during turning.
