Problem: Clunking Noise When Turning in 2023 Toyota Highlander

Tools Required:

Jack and jack stands
Torque wrench
Socket and ratchet set
Pry bar
Inspection mirror
Flashlight
Mechanic's stethoscope (optional)

Repair Instructions:

Step 1: Raise the Vehicle

Park the vehicle on a flat surface and engage the parking brake.
Use a jack to lift the front of the vehicle and secure it with jack stands.

Step 2: Check Suspension and Steering Components

Inspect the control arms, bushings, and strut mounts for any wear or damage.
If any components are found to be worn or damaged, replace them as necessary.

Step 3: Inspect and Replace CV Joints (if necessary)

If the CV joints are determined to be the source of the noise, remove the wheel and tire.
Remove the axle nut using a socket and ratchet.
Disconnect the lower control arm from the steering knuckle if necessary for better access.
Pull the axle out from the hub assembly and inspect the CV joints.
If damaged, replace the CV joint or the entire axle assembly.

Step 4: Tighten Loose Components

Use a torque wrench to tighten all suspension and steering component bolts to the manufacturer's specifications. Refer to the vehicle's service manual for specific torque values.
Pay special attention to the bolts connecting the control arms and sway bar links.

Step 5: Test Drive

Reassemble any components that were removed during the inspection.
Lower the vehicle back to the ground and take it for a test drive.
Replicate the conditions that caused the initial clunking noise to ensure the problem has been resolved.

Step 6: Further Diagnosis (if noise persists)

If the noise continues, further inspect the steering rack and power steering system.
If needed, consult with a professional technician or visit a dealership for advanced diagnosis.

Conclusion

Clunking noises during turning in a 2023 Toyota Highlander can often be traced back to worn or loose suspension and steering components, particularly CV joints. Following these detailed diagnostic steps and repair instructions will help identify and rectify the issue efficiently. Always refer to the vehicle's service manual for specific details and torque specifications.
