Solution

1. Tire Inspection and Maintenance

Check Tire Pressure: Ensure all tires are inflated to the manufacturer's recommended pressure.
Inspect for Damage: Look for bulges, cuts, or any visible damage on tires.
Rotate Tires: If uneven wear is found, rotate tires to promote even wear.

2. Wheel Balancing

Remove Wheels: Jack up the vehicle and remove the wheels.
Balance Each Wheel: Use a wheel balancer to check and adjust the weight distribution on each wheel.
Reinstall Wheels: Torque the lug nuts to the manufacturer's specifications.

3. Suspension Check

Inspect Components: Check struts, shocks, and bushings for signs of wear or damage.
Replace Worn Parts: If any components are worn, replace them with OEM or quality aftermarket parts.
Reassemble: Ensure all components are properly secured.

4. Wheel Alignment

Set Up Alignment Equipment: Position the vehicle on an alignment rack.
Adjust Alignment Settings: Follow the manufacturer's specifications to adjust toe, camber, and caster angles.
Test Drive: After alignment, take the vehicle for a test drive to ensure vibrations are resolved.
