why is my Volkswagen Golf MK7 (2015-2019) making a popping noise when turning

Solution

1. Preparation

• Gather tools: jack and jack stands, socket set, torque wrench, pry bar, and OBD-II scanner.
• Ensure the vehicle is parked on a level surface and the ignition is off.
• Disconnect the battery to avoid any electrical issues while working.

2. Inspect and Replace CV Joints

• Use the jack to lift the front of the vehicle and secure it with jack stands.
• Remove the wheel using a socket set.
• Check the CV joint boots for cracks or leaks; if damaged, proceed to replace the CV joint.
  • Sub-steps:
    • Remove the axle nut using a socket and breaker bar.
    • Disconnect the lower control arm to free the CV joint from the hub.
    • Slide the old CV joint out and insert the new one, making sure it is properly seated.
    • Reassemble the lower control arm and torque the axle nut to the manufacturer's specifications (typically 250 Nm).

3. Inspect and Replace Suspension Components

• Check the strut mounts and sway bar links for wear.
• If damaged, replace them as follows:
  • Sub-steps:
    • Remove any components obstructing access to the strut mount and sway bar links.
    • Use a socket set to remove bolts securing the strut mount and sway bar link.
    • Install new components, ensuring all bolts are tightened to the specified torque (typically 30-40 Nm for sway bar links).

4. Reassemble and Lower the Vehicle

• Reinstall the wheel and tighten the lug nuts in a crisscross pattern to ensure even pressure.
• Lower the vehicle from the jack stands and torque the lug nuts to the specified value (usually 120 Nm).
