Volkswagen Passat B8 (2015-2022) shaking at high speeds, what should I check?

Solution

1. Preparation

• Gather Tools and Parts: Ensure you have a socket set, torque wrench, jack stands, wheel balancer, and alignment tools.
• Safety Precautions: Park the vehicle on a flat surface, engage the parking brake, and wear safety goggles.

2. Inspect and Replace Tires (if necessary)

• Remove the wheel covers or hubcaps.
• Loosen lug nuts slightly while the vehicle is on the ground.
• Lift the vehicle using a jack and secure it with jack stands.
• Remove the wheels and inspect for uneven wear or damage.
• If tires are worn, replace them with new tires, ensuring to match the specifications for the Passat.
• Reinstall the wheels, tightening the lug nuts to the manufacturer's torque specifications.

3. Wheel Balancing

• Mount the tires on a wheel balancer.
• Spin the tires to check for any imbalance.
• Add wheel weights as needed to achieve balance.
• Remount the balanced wheels on the vehicle.

4. Check and Adjust Wheel Alignment

• Use an alignment machine to measure alignment angles.
• Adjust caster, camber, and toe settings according to manufacturer specifications.
• Test drive the vehicle post-alignment to ensure straight tracking.

5. Inspect Suspension and Brake Components

• Visually inspect suspension components for wear or damage.
• Replace any worn parts such as bushings or tie rods.
• Check the brake rotors for warping using a runout gauge; replace if warped.
