why does my Volkswagen Tiguan make a clunking noise when driving over bumps?

Solution

1. Preparation

• Tools Required: Jack, jack stands, lug wrench.
• Park the vehicle on a flat surface, engage the parking brake, and ensure the engine is off.

2. Lift the Vehicle

• Use the jack to lift the vehicle at the designated lift points.
• Secure the vehicle with jack stands to ensure safety.

3. Inspect and Replace Suspension Components

• Sub-steps:
  1. Remove the wheel using the lug wrench.
  2. Inspect the struts and shocks for leaks or physical damage.
  3. Check the control arm bushings and ball joints for wear; replace them if cracked or loose.
  4. If struts or shocks are worn, remove and replace them:
     • Unbolt the top mount from the strut tower inside the engine bay.
     • Remove the bottom bolts securing the strut to the knuckle.
     • Replace with new struts/shocks and torque bolts to manufacturer specifications.
  5. Reattach any loose components, ensuring all bolts are tightened to the specified torque.

4. Reassemble and Lower the Vehicle

• Reinstall the wheel and hand-tighten the lug nuts.
• Lower the vehicle from the jack stands and remove the jack.
• Torque the lug nuts to the manufacturer's specified torque.
