why does my Volkswagen Passat B8 (2015-2022) make a grinding noise when turning

Solution

1. Preparation

• Park the vehicle on a level surface and set the parking brake.
• Gather necessary tools and safety equipment.

2. Inspect Power Steering System

• Tools Required: OBD-II scanner, funnel, power steering fluid
• Check the power steering fluid level using the dipstick.
• If low, top off with the manufacturer-recommended power steering fluid.
• Inspect the fluid for contamination; if contaminated, a complete flush and refill may be required.

3. Check CV Joints

• Tools Required: Jack, jack stands, socket set
• Raise the front of the vehicle using a jack and secure with jack stands.
• Remove the front wheels for better access to the CV joints.
• Inspect the CV boots for tears or leaks; replace if necessary.
• Check the CV joints for play; if damaged, replace the entire axle assembly.

4. Examine Suspension Components

• Tools Required: Torque wrench, socket set
• Inspect control arms and bushings for wear or damage.
• Check struts for leaks or signs of wear; replace if necessary.
• Retighten any loose suspension bolts to manufacturer specifications.

5. Inspect Wheel Bearings

• Tools Required: Wheel bearing puller (if necessary)
• Spin the wheel by hand to listen for any grinding or roughness.
• If noise is present, replace the wheel bearings. Follow the manufacturer specifications for torque settings during reassembly.
