Problem: Popping Noise from the Front End of a 2020 Toyota Highlander
Possible Causes:
  1. Worn or Damaged CV Joints: Constant Velocity (CV) joints can wear out and make popping noises, especially when turning.
  2. Loose or Damaged Suspension Components: This may include control arms, bushings, or sway bar links.
  3. Strut Issues: Worn strut mounts or struts themselves can lead to noises when compressing or extending.
  4. Wheel Bearings: A failing wheel bearing may produce a popping or grinding noise.
  5. Loose Fasteners: Bolts or nuts in the steering or suspension system can become loose.
Repair Instructions:

Step 1: Repair or Replace CV Joints

  • If CV joints are found to be damaged:
    • Tools Required: CV joint tool kit.
    • Remove the wheel and brake components.
    • Disconnect the axle nut and remove the half-shaft. Replace with a new CV joint or axle assembly as needed.
    • Reassemble in reverse order and torque all fasteners.

Step 2: Replace Worn Suspension Components

  • If any bushings, control arms, or sway bar links are found to be worn:
    • Tools Required: Socket set, ball joint separator.
    • Remove the damaged components, ensuring to note how they are assembled.
    • Install new parts and torque to specifications.

Step 3: Replace Struts or Strut Mounts

  • If struts or mounts are worn:
    • Tools Required: Strut spring compressor, jack, jack stands, socket set.
    • Remove the strut assembly from the vehicle. Use a spring compressor to remove the spring from the strut if necessary.
    • Replace the strut or strut mount as needed and reassemble.

Step 4: Replace Wheel Bearings

  • If wheel bearings are failing:
    • Tools Required: Bearing puller, socket set, torque wrench.
    • Remove the wheel and hub assembly.
    • Use a bearing puller to remove the old bearing and press in the new bearing.
    • Reassemble the hub and wheel, ensuring all fasteners are torqued properly.
Final Checks:
  • After performing repairs, take the vehicle for a test drive to ensure the popping noise has been resolved.
  • Inspect the front end again after the test drive to ensure there are no new issues or loose components.
Conclusion:

If the issue persists after performing these diagnostic and repair steps, further inspection by a professional technician may be required to identify any hidden problems.
