Problem: Popping Sound When Turning in a Toyota Highlander Fourth Generation (2020-present)
Potential Causes
  1. CV Joint Issues: Worn or damaged Constant Velocity (CV) joints can produce a popping sound when under load during turns.
  2. Suspension Components: Worn bushings, ball joints, or struts may lead to noise when the suspension is compressed or extended during turns.
  3. Wheel Bearings: A failing wheel bearing may cause noise that is more noticeable during turning.
  4. Tires: Improperly inflated, worn, or damaged tires can create noise when turning.
  5. Brake Components: Loose or worn brake components (calipers, pads) may produce noise during turns.
Tools Required
  • Jack and jack stands
  • Lug wrench
  • Torque wrench
  • Socket set
  • Pliers
  • Mechanic's creeper (optional)
  • Inspection mirror
  • Flashlight
Repair Instructions

Step 1: Raise the Vehicle

  1. Park the vehicle on a flat surface and engage the parking brake.
  2. Loosen the lug nuts slightly with a lug wrench.
  3. Use a jack to lift the vehicle and secure it with jack stands.
  4. Remove the wheels for better access to suspension and CV components.

Step 2: Inspect the CV Joints

  1. Examine the boots of the CV joints for tears or leaks.
  2. If the boots are damaged, replace the CV joint.
    • Replacement Instructions:
      • Remove the axle nut (may require a breaker bar).
      • Disconnect the lower control arm or strut to free the CV axle.
      • Pull out the old CV joint and install the new one, ensuring to secure the boots properly.

Step 3: Check Suspension Components

  1. Inspect bushings, ball joints, and struts for wear.
  2. If any component is worn, replace it.
    • Replacement Instructions for Struts:
      • Remove the strut assembly by unbolting it from the top and bottom mounts.
      • Replace the strut cartridge (if applicable) or the entire strut assembly.
      • Reinstall and torque to specifications.

Step 4: Inspect Wheel Bearings

  1. Spin the wheel to check for noise.
  2. If the bearing is faulty, replace it.
    • Replacement Instructions:
      • Remove the brake caliper and rotor.
      • Unscrew the wheel hub assembly and replace the bearing.
      • Reassemble everything and torque to specifications.

Step 5: Check and Replace Brake Components

  1. Inspect brake pads and calipers.
  2. Replace any worn brake pads or ensure calipers are properly secured.
Final Steps
  1. Reinstall the wheels and lightly tighten the lug nuts.
  2. Lower the vehicle and torque the lug nuts to the manufacturer's specifications.
  3. Take the vehicle for a test drive to ensure the popping sound is resolved.
Conclusion

If the popping sound persists after following these steps, it may be advisable to consult a professional technician for further diagnostics, as it could indicate a more complex issue with the drivetrain or suspension system.
