Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface.
Use wheel chocks to prevent movement.

2. Tire Inspection

Remove the wheel covers or hubcaps if present.
Inspect each tire for bulges, cracks, or punctures.
Measure tread depth with a tread depth gauge; replace if below 2/32".

3. Tire Balancing

Mount the tire on a wheel balancing machine.
Adjust weights as necessary to balance the tire.
Reinstall the balanced tire onto the vehicle.

4. Wheel Alignment

Use a wheel alignment machine to measure alignment angles.
Adjust camber, caster, and toe angles to meet the manufacturer's specifications.
Tighten all adjustment bolts securely.

5. Suspension and Drivetrain Inspection

Raise the vehicle using a jack and support it with jack stands.
Inspect suspension components for visible wear or damage; replace any faulty parts.
Check wheel bearings for play by rocking the wheel back and forth; replace if worn.
