Problem Diagnosis: Loud Popping Sound When Turning in 2020 Toyota Highlander

Possible Causes
  1. CV Joint Failure: A worn or damaged constant velocity (CV) joint may cause popping sounds while turning.
  2. Suspension Issues: Problems with suspension components such as control arms, bushings, or struts may cause noises.
  3. Steering Components: Worn steering rack or tie rod ends can lead to popping sounds during turns.
  4. Wheel Bearings: A failing wheel bearing can create noise when turning.
  5. Brake Components: Loose or damaged brake pads or calipers could also contribute to the noise.
Tools Required
  • Jack and jack stands
  • Socket set (metric)
  • Wrench set
  • Torque wrench
  • Pry bar
  • Chassis ear (optional for noise amplification)
  • Mechanic’s creeper
  • Safety goggles and gloves
Repair Instructions

If CV Joint is the Culprit:

  1. Remove the Wheel:

    • Use a socket wrench to remove the lug nuts and take off the wheel.

  2. Remove the Axle Nut:

    • Depending on the design, you may need to remove the brake caliper and rotor to access the axle nut.
    • Use a breaker bar if the nut is torqued tightly.

  3. Replace the CV Joint:

    • Disconnect the lower control arm or strut from the knuckle if necessary.
    • Pull out the axle from the transmission side and replace with a new CV axle assembly.
    • Reassemble in reverse order.

If Suspension Components are Worn:

  1. Replace Control Arm/Bushings:
    • Remove the old control arm from the vehicle by unbolting it from the frame and knuckle.
    • Install new control arm or bushings and torque to specifications.

If Steering Components are Worn:

  1. Replace Tie Rod Ends:
    • Remove the tie rod from the steering knuckle.
    • Install the new tie rod end and adjust the alignment afterward.

If Wheel Bearings are Failing:

  1. Replace Wheel Bearing:
    • Remove the wheel and brake components.
    • Use a bearing puller to remove the old bearing.
    • Install the new bearing and reassemble the wheel.
Final Steps
  • After repairs, always perform a test drive to ensure that the popping sound has been eliminated.
  • Recheck all fasteners and components for tightness.
  • If the problem persists, consider consulting a professional for further diagnostics.
Safety Precautions
  • Always wear safety goggles and gloves when working on vehicle components.
  • Ensure the vehicle is on a flat, stable surface when lifting and working under it.
  • Use the proper torque specifications when reassembling components to avoid future issues.
