my Volkswagen Golf MK5 (2004-2008) makes a loud noise when turning, what's the issue?

Solution

1. Preparation

• Gather all necessary tools and parts.
• Park the vehicle on a level surface and engage the parking brake.
• Disconnect the negative battery terminal for safety.

2. Inspect Power Steering System

• Check the power steering fluid level; top it off if low with the recommended fluid type.
• Inspect power steering hoses for leaks or cracks.
• If the fluid is dark or contaminated, consider flushing the system.

3. Check CV Joints and Boots

• Raise the front of the vehicle using a jack and secure it with jack stands.
• Visually inspect the CV boots for any tears or leaks.
• If damaged, replace the CV joint assembly.
  • Tools Required: Socket set, pry bar, torque wrench.
  • Sub-steps:
    • Remove the wheel.
    • Disconnect the axle nut using a socket.
    • Remove the retaining clips and disconnect the CV joint from the transmission.
    • Install the new CV joint in reverse order, ensuring to torque the axle nut to the manufacturer’s specifications.

4. Inspect Suspension Components

• Examine the control arms, bushings, and shock absorbers for signs of wear or damage.
• Replace any worn components as necessary.
  • Tools Required: Wrench set, socket set.
  • Sub-steps:
    • Remove the affected part (e.g., control arm).
    • Replace with new parts and torque to specifications.

5. Check Wheel Bearings

• Spin the wheel to listen for any grinding noises.
• If noise is present, replace the wheel bearing assembly.
  • Tools Required: Bearing puller, socket set, torque wrench.
  • Sub-steps:
    • Remove the wheel and brake components.
    • Use a bearing puller to remove the old bearing.
    • Install the new bearing and reassemble components.
