Diagnosing a Clunking Noise When Turning in a 2020-Present Toyota Highlander (XU70)

Step 1: Preliminary Inspection

Tools Required:

  • Flashlight
  • Mechanic's creeper (optional)
  • Stethoscope (optional)
  1. Visual Inspection:
    • Park the vehicle on a flat, level surface.
    • Inspect the front suspension components, including the control arms, ball joints, tie rod ends, and sway bar links for any signs of damage, wear, or looseness.
    • Check for any loose or damaged underbody panels.
Step 2: Test Drive
  1. Conduct a Test Drive:
    • Drive the vehicle in a safe area and replicate the conditions that cause the noise.
    • Make sharp turns both left and right while listening for the clunking noise.
    • Note any correlation between speed and the noise.
Step 3: Inspect the Suspension System

Tools Required:

  • Jack and jack stands
  • Torque wrench
  • Socket set
  • Pry bar
  • Wheel chocks

  1. Lift the Vehicle:

    • Securely lift the front of the vehicle using a jack and support it with jack stands.
    • Ensure the vehicle is stable before proceeding.

  2. Check Ball Joints:

    • Use a pry bar to apply leverage to the lower control arm while observing the ball joints.
    • Look for excessive movement or play in the joints.

  3. Inspect Tie Rod Ends:

    • Grasp the tie rod ends and shake them to check for play.
    • A clunk may originate from worn tie rod ends.

  4. Examine Sway Bar Links:

    • Inspect sway bar links for wear or damage.
    • Check for any loose connections that may cause the clunking noise.

  5. Check CV Joints:

    • Inspect the CV joints for any torn boots or grease leakage.
    • Rotate the wheels while observing the CV axles for any clunking noise or movement.
Step 4: Check Steering Components

Tools Required:

  • Torque wrench
  • Socket set

  1. Inspect the Steering Rack:

    • Check for any signs of loose or damaged steering rack mounts.
    • Tighten any loose bolts to the manufacturer's specifications.

  2. Examine Steering Column:

    • Inspect the steering column for any loose connections or components that may cause noise when turning.
Step 5: Additional Component Checks

  1. Check Brake Components:

    • Inspect the brake calipers and brackets to ensure they are secure and not causing noise during turns.
    • Look for any loose brake pads or hardware.

  2. Inspect Wheel Bearings:

    • Spin the wheels by hand to check for roughness or play in the wheel bearings.
    • If noise is present, the wheel bearings may need replacement.
Repair Instructions
Step 1: Repair or Replace Worn Components

  1. Ball Joints:

    • If worn, replace ball joints according to manufacturer specifications.
    • Use a socket set to remove the retaining bolts and install new units.

  2. Tie Rod Ends:

    • If damaged, disconnect the tie rod end from the steering knuckle and replace it.
    • Torque the new tie rod end to the specified torque.

  3. Sway Bar Links:

    • Remove and replace worn sway bar links.
    • Ensure proper torque on all connection points.

  4. CV Joints:

    • If the CV joints are damaged, replace the entire axle assembly or just the joint as needed.

  5. Steering Components:

    • Tighten any loose steering rack or column components, ensuring they are to the manufacturer's specifications.
Step 2: Reassemble and Test

  1. Reassemble:

    • Reinstall any removed components and ensure that all bolts are torqued to the correct specifications.

  2. Lower the Vehicle:

    • Carefully lower the vehicle from jack stands and remove wheel chocks.

  3. Test Drive Again:

    • Conduct another test drive to confirm that the clunking noise has been resolved.
    • Check for any additional noises or issues during the drive.
Conclusion

If the clunking noise persists after following these diagnostic and repair steps, further inspection by a professional technician may be required to explore more complex issues such as internal transmission problems or differential issues.
