Solution

1. Preparation

Ensure the vehicle is parked on a level surface.
Gather necessary tools and parts.
Tools Required: Jack and jack stands, socket set, torque wrench, pry bar, and a rubber mallet.

2. Remove Wheel

Loosen lug nuts slightly while the vehicle is on the ground.
Lift the vehicle using a jack and secure it with jack stands.
Completely remove the lug nuts and take off the wheel.

3. Inspect Suspension Components

Examine the control arms and their bushings for wear or damage; replace any worn bushings.
Use a pry bar to check for play in the ball joints; if excessive play is found, replace the ball joint assembly.
Inspect the sway bar links for damage and replace if necessary.

4. Check Shock Absorbers

Perform the bounce test; if the vehicle continues to bounce excessively, consider replacing the shock absorbers.
Remove the shock absorber as per the manufacturer’s specifications (usually involves removing bolts at the top and bottom).
Replace with a new shock absorber, ensuring proper torque specifications are followed during installation.

5. Reassemble

Reattach the wheel and hand-tighten the lug nuts.
Lower the vehicle and torque the lug nuts to the manufacturer’s specifications (typically around 90-100 ft-lbs for the Golf MK7).

6. Test Drive

Take the vehicle for a test drive to ensure the rattling noise is resolved.
