my Skoda Octavia NFL (2020-Present) makes a clunking noise when going over bumps, what could it be?

Solution

1. Preparation

• Gather all necessary tools and parts.
• Ensure the vehicle is parked on a flat surface and the parking brake is engaged.
• Wear safety glasses and gloves.

2. Lift the Vehicle

• Use a jack to lift the vehicle securely and place jack stands under the frame.
• Remove the wheels to gain access to the suspension components.

3. Inspect and Replace Suspension Components

• Inspect the Struts:

  • Check for any signs of leakage or damage.
  • If damaged, remove the struts using a socket set (typically 17mm to 21mm bolts).
  • Replace with OEM or high-quality aftermarket struts as needed.

• Check Sway Bar Links:

  • Remove the sway bar link bolts (usually 12mm to 15mm).
  • Replace any worn links or bushings with new ones.

• Inspect Control Arms:

  • Look for damaged control arm bushings or cracked arms.
  • Replace if necessary, ensuring to torque bolts to the manufacturer's specifications (consult repair manual for exact torque values).

4. Reassemble and Test

• Reattach wheels and lower the vehicle back to the ground.
• Tighten all bolts to specification and ensure everything is secure.

5. Final Inspection

• Perform a road test to ensure the clunking noise is resolved.
• Recheck all components for tightness post-test drive.
