why does my Toyota Highlander Fourth Generation (2020-present) make a clunking noise when going over...

Solution

1. Preparation

• Gather tools and parts.
• Park the vehicle on a level surface and engage the parking brake.
• Wear safety glasses and gloves.

2. Lift the Vehicle

• Use a hydraulic jack to lift the front or rear of the vehicle as needed.
• Securely place jack stands under the vehicle to eliminate any risk of falling.

3. Inspect and Replace Worn Components

• Struts/Shocks:

  • Remove the wheel to access the strut assembly.
  • Disconnect the strut from the upper mount and lower control arm.
  • Replace the strut/shock if worn or damaged.
  • Reinstall the new strut and torque bolts to manufacturer's specifications (typically around 50-70 ft-lbs).

• Sway Bar Links:

  • Inspect the sway bar links and bushings for wear.
  • If damaged, remove the bolts securing the sway bar link to the sway bar and control arm.
  • Install new sway bar links, ensuring proper torque (approximately 30-40 ft-lbs).

4. Reassemble and Lower Vehicle

• Reinstall the wheel and torque the lug nuts to the manufacturer's specification (usually around 80-100 ft-lbs).
• Carefully lower the vehicle from the jack stands and remove the jack.

5. Final Inspection

• Conduct a final visual inspection of the replaced components.
• Ensure all fasteners are properly tightened and secured.
