Diagnosis and Repair of Strange Noise When Turning in a 2020 Toyota Highlander

Possible Causes
  1. Worn or Damaged CV Joints
  2. Low Power Steering Fluid
  3. Worn Steering Rack
  4. Bad Wheel Bearings
  5. Suspension Issues (e.g., worn bushings or struts)
Tools Required
  • Floor jack and jack stands
  • Wheel chocks
  • Torque wrench
  • Socket set
  • Screwdrivers
  • Pliers
  • Pry bar
  • Power steering fluid
  • Stethoscope or mechanic's stethoscope
  • Inspection mirror
  • Flashlight
Step 1: Safety First
  1. Park the Vehicle: Ensure the vehicle is parked on a level surface and the engine is off.
  2. Engage Parking Brake: Activate the parking brake to prevent rolling.
Step 2: Inspect for Power Steering Fluid
  1. Locate the Power Steering Reservoir: Open the hood and find the power steering fluid reservoir.
  2. Check Fluid Level: Remove the cap and check the fluid level against the dipstick or markings on the reservoir.
    • If Low: Top off with the manufacturer-recommended power steering fluid and check for leaks.
Step 3: Inspect CV Joints
  1. Lift the Front of the Vehicle: Use a floor jack to lift the front and secure it with jack stands.
  2. Inspect CV Boots: Look for torn or damaged CV boot covers on both sides.
  3. Check for Play: Grasp the axle and check for excessive play or clicking noises while turning the wheel.
    • Repair/Replace if Necessary: If damaged, the CV joint will need to be replaced.
Step 4: Check Wheel Bearings
  1. Spin the Wheels: While the vehicle is lifted, spin each front wheel to listen for any grinding noises.
  2. Check for Play: Grasp the wheel at 12 and 6 o’clock positions and shake it. Excessive play could indicate a bad wheel bearing.
    • Replace Wheel Bearings: If they are worn, they will need to be replaced.
Step 5: Examine the Steering Rack
  1. Inspect Steering Rack Boots: Check for leaks or damage.
  2. Listen for Noise: With the engine running, have someone turn the steering wheel while you listen under the vehicle.
    • If Noisy: A failing steering rack may need to be replaced.
Step 6: Inspect Suspension Components
  1. Check Bushings and Struts: Inspect the suspension components for wear, especially the control arm bushings and struts.
    • Look for Cracks or Separation: Replace any worn or damaged components.
Repair Instructions
Repair CV Joints
  1. Remove the Wheel: Use a socket set to remove the lug nuts and take off the wheel.
