Solution

If your 2020 Toyota Highlander is making a popping sound when turning, it is essential to diagnose the issue properly to avoid further damage and ensure safety. Below is a detailed step-by-step guide to help you diagnose and potentially fix the problem.

Possible Causes

CV Joint Failure: A worn or damaged constant velocity (CV) joint can cause popping noises when turning.
Suspension Issues: Worn bushings, strut mounts, or ball joints can cause noise and instability.
Wheel Bearing Failure: A failing wheel bearing can also produce a popping or grinding sound.
Loose or Damaged Components: Loose bolts or damaged components in the steering or suspension system can lead to abnormal noises.

Tools Required

Jack and jack stands
Lug wrench
Socket set
Torque wrench
Pry bar
Inspection mirror
Chassis ear or stethoscope (optional for noise diagnosis)
CV joint grease (if applicable)

Repair Instructions

If the CV Joint is Worn/Damaged:

Remove the Wheel:
- Use the lug wrench to remove the lug nuts and take off the wheel.
Remove the Axle:
- Remove the axle nut using a socket.
- Disconnect any components blocking access to the CV joint (such as brake calipers, if necessary).
- Use a pry bar to pop the CV joint out of the hub.
Install New CV Joint:
- Insert the new CV joint into place, ensuring it is seated properly.
- Reassemble the hub and torque the axle nut to specifications.
- Reinstall the wheel and lower the vehicle.

If Suspension Components are Worn:

Replace Faulty Parts:
- For worn bushings, ball joints, or strut mounts, you will need to disassemble the affected suspension components.
- Replace the worn parts with new ones, ensuring proper torque specifications are followed during reassembly.
Recheck Alignment:
- After any suspension work, it is advisable to have a professional alignment performed.

Final Steps

Test Drive Again: After completing repairs, take the vehicle for a test drive to ensure the popping sound is resolved.
Monitor Performance: Keep an eye on any unusual noises or handling issues in the following days.

Conclusion

If the popping noise persists after these inspections and repairs, consider seeking the assistance of a certified mechanic. They will have access to specialized equipment and knowledge to diagnose more complex issues that may not be evident through visual inspection alone.
