Solution

1. Tire Inspection

Remove the wheel covers if applicable.
Inspect each tire for uneven wear, bulges, or punctures.
Replace any damaged tires as necessary.

2. Wheel Balancing

Remove the wheels from the vehicle using a socket set.
Mount the wheels on a wheel balancer.
Adjust the weights on the rims as needed until balanced properly.
Reinstall the wheels, ensuring correct torque (typically 76 ft-lbs for Toyota Corolla).

3. Wheel Alignment

Use a laser alignment tool to check the alignment angles (toe, camber, caster).
Adjust the alignment settings according to manufacturer specifications.
Test drive again to ensure vibrations have been resolved.

4. Suspension Inspection

Visually inspect suspension components for signs of damage or excessive wear.
Replace any worn struts, shocks, or control arms.
Ensure all bolts and fasteners are tightened to manufacturer specifications.
