Grinding Noise During Turns in a 2022 Toyota Highlander

Potential Causes

Worn brake pads or rotors.
Damaged wheel bearings.
Issues with the CV joints or axles.
Low power steering fluid.
Problems with the suspension components.

Step 1: Perform a Visual Inspection

Park the Vehicle: Ensure the vehicle is on a flat surface and turn off the engine.
Check Wheel Area: Inspect the wheel wells for any visible damage or debris.
Inspect Brake Components: Look for uneven wear on brake pads and any scoring on rotors.
Check CV Joints: Look for cracks or tears in the CV boot.

Step 2: Listen for the Noise

Start the Engine: With the vehicle still stationary, turn the steering wheel left and right.
Identify Noise Source: Determine if the grinding noise is coming from the front or rear wheels.

Step 3: Check Fluid Levels

Power Steering Fluid: Check the power steering fluid level. Low fluid can lead to noise during turns.
Transmission Fluid: Make sure the transmission fluid is at the correct level, as low fluid can affect steering.

Step 4: Test Drive

Take a Test Drive: Drive the vehicle slowly and listen for the grinding noise while turning.
Sharp Turns: Make sharper turns to see if the noise becomes more pronounced.

Tools Required

Repair Instructions

Repair Option 1: Brake Components

Jack Up the Vehicle: Use a jack to lift the front or rear of the vehicle, depending on where the noise is coming from. Secure with jack stands.
Remove Wheels: Use a lug wrench to take off the wheels.
Inspect Brake Pads and Rotors:
- Remove the caliper by unscrewing the caliper bolts.
- Inspect the brake pads for wear (less than 3mm thickness indicates replacement is needed).
- Check the rotor surface for scoring or warping.
Replace Brake Pads/Rotor (if necessary):
- If pads are worn, replace them with new ones. Ensure to apply brake grease where necessary.
- If the rotors are scored or warped, replace them as well.
Reassemble: Reattach the caliper, tighten the bolts to the manufacturer’s specifications, and reattach the wheels.

Repair Option 2: CV Joints

Inspect CV Joints: If there are visible cracks in the CV boot or if the noise is coming from the front axle during turns:
- Remove the axle nut and disconnect the CV joint from the wheel hub.
- Inspect the joint for play or damage.
Replace CV Joint (if necessary):
- If damaged, replace the CV joint or the entire axle assembly.
- Install the new CV joint and reattach the axle to the hub.

Repair Option 3: Wheel Bearings

Check Wheel Bearings: If the noise persists and seems to come from the hub area:
- Remove the wheel and inspect the wheel bearings for any play or roughness.
Replace Wheel Bearings (if necessary):
- Remove the hub assembly and press out the old bearings.
- Press in new bearings and reassemble the hub.

Final Steps

Check Power Steering Fluid: If low, top off with the recommended type.
Test Drive Again: After repairs, take the vehicle for another test drive to ensure that the grinding noise is eliminated.
Re-check All Work: Ensure that all components are properly secured and that the vehicle is safe for operation.

Conclusion

If the grinding noise persists after performing these diagnostics and repairs, or if you are not comfortable performing these repairs, consult a certified automotive technician for further assistance.
