why does my Volkswagen Golf MK7.5 (2020-Present) make a clunking noise

Solution

1. Preparation

• Gather tools and parts required for the repair.
• Ensure the vehicle is parked on a level surface and safely elevated using jack stands.
• Disconnect the battery if working on electrical components.

2. Inspect and Replace Suspension Components

• Sub-steps:
  1. Remove the wheel to access suspension components.
  2. Visually inspect control arm bushings for cracks or excessive play.
  3. If damaged, remove the control arm using a socket set and replace with new components.
  4. Torque the new control arm bolts to the manufacturer's specifications (usually around 40-50 Nm).

3. Check and Replace Drivetrain Components

• Sub-steps:
  1. Inspect CV joints for any signs of wear or torn boots.
  2. If damage is found, remove the axle from the transmission and replace the CV joint.
  3. Reinstall the axle and ensure all bolts are torqued properly to the specification (typically around 70-80 Nm).

4. Examine Engine and Transmission Mounts

• Sub-steps:
  1. Inspect the engine mounts for signs of cracks or separation.
  2. If any mounts are found to be defective, remove the bolts securing the mount to the engine and frame.
  3. Replace with new mounts and torque bolts according to the manual (usually around 20-30 Nm).

5. Test Drive and Finalize

• Conduct a test drive to ensure the clunking noise has been resolved.
• Recheck all replaced components for tightness.
