When your 2021 Toyota Highlander is making strange noises during turns, it can be concerning. The noises could be indicative of various issues, ranging from minor to more serious mechanical problems. Below are the detailed steps you should follow to diagnose and potentially resolve the issue.

Tools Required
  • Jack and jack stands
  • Wheel chocks
  • Socket set and wrenches
  • Torque wrench
  • Screwdrivers
  • Power steering fluid (if needed)
  • Flashlight
  • Inspection mirror
Repair Instructions

If Power Steering Fluid is Low:

  1. Locate the power steering reservoir and check the fluid level.
  2. If low, add fluid as per the manufacturer’s specifications.
  3. Start the engine and turn the steering wheel from lock to lock to bleed air from the system.

If CV Joints are Worn:

  1. Remove the wheel and axle nut.
  2. Disconnect the lower control arm from the wheel hub (if applicable).
  3. Pull the CV axle from the transmission (may require a pry bar).
  4. Replace the CV joint or entire axle assembly as necessary.
  5. Reassemble and torque all components to manufacturer specifications.

If Wheel Bearings are Bad:

  1. Remove the wheel and brake components.
  2. Remove the hub assembly to access the wheel bearings.
  3. Press out the old bearings and install new ones using a bearing press.
  4. Reassemble all components and torque to specifications.

If Suspension Components are Worn:

  1. Identify the worn component (ball joint, bushing, etc.).
  2. Remove the affected component using appropriate tools.
  3. Install the new part and ensure it’s torqued to specifications.
  4. Repeat for any other worn components.

If Brake Pads are Worn:

  1. Remove the wheel and caliper.
  2. Replace the brake pads and inspect the rotor for wear.
  3. Reassemble the caliper and wheel, ensuring all bolts are torqued.
Final Steps
  1. Test Drive: After performing the necessary repairs, take the vehicle for a test drive. Listen for any remaining noises and observe the handling.
  2. Alignment Check: If any suspension components were replaced or adjusted, consider having a wheel alignment done to ensure proper vehicle handling and tire wear.

By following these steps, you should be able to diagnose and address the strange noises your 2021 Toyota Highlander is making during turns. If you're unable to identify the issue or the problem persists, consult with a qualified technician for further diagnosis.
