Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a flat surface and engage the parking brake.
Disconnect the battery if necessary for electrical components.

2. Inspect Suspension Components

Tools Required: Socket set, torque wrench.
Remove the front wheel to gain access to the suspension.
Inspect control arms, struts, and bushings for any visible damage or wear.
Tighten any loose bolts to the manufacturer's specifications.

3. Check Power Steering Fluid

Tools Required: Clean rag, funnel.
Remove the power steering fluid reservoir cap.
Check the fluid level; if low, add the appropriate power steering fluid recommended by Volkswagen.
If the fluid is dirty, consider flushing and replacing it.

4. Examine Wheel Bearings

Tools Required: Jack stands, socket set.
Lift the front of the vehicle and secure it on jack stands.
Grab the top and bottom of the wheel and shake it; there should be no play.
If there is play, the wheel bearing may need to be replaced.

5. Inspect CV Joints

Tools Required: Pliers, socket set.
Check the CV boots for cracks or tears; replace if damaged.
If the CV joint is damaged, it must be removed and replaced with a new one.
