Solution

1. Preparation

Tools Required: Floor jack, jack stands, tire pressure gauge, wheel balancer, alignment machine
Ensure vehicle is parked on a level surface and the parking brake is engaged.

2. Tire Balancing

Sub-steps:
1. Lift the vehicle using a floor jack and secure it with jack stands.
2. Remove the wheel that is vibrating.
3. Mount the wheel on a wheel balancer.
4. Spin the wheel to determine the imbalance.
5. Attach the appropriate weights to the wheel rim as indicated by the balancer.
6. Reinstall the wheel on the vehicle and torque the lug nuts to the manufacturer’s specifications.

3. Tire Inspection and Replacement (if necessary)

Sub-steps:
1. Check the tires for any visible damage such as cuts, bulges, or punctures.
2. Measure tread depth across the tire surface; if below the minimum requirement, replace the tires.
3. If uneven wear is identified, consider rotating or replacing tires as needed.

4. Wheel Alignment

Sub-steps:
1. Take the vehicle to a professional alignment shop.
2. Follow the technician's instructions for alignment adjustment.
3. Ensure that camber, caster, and toe align with the manufacturer's specifications.

5. Suspension and Drivetrain Inspection
