Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a flat surface and set the parking brake.
Ensure the vehicle is cool before starting work.

2. Adjust Tire Pressure

Use a tire pressure gauge to check the pressure of all tires.
Inflate or deflate tires to match the recommended pressure found on the door jamb sticker.

3. Wheel Balancing

Remove the wheel covers or hubcaps if applicable.
Mount the wheels on a wheel balancing machine.
Add or remove weights as needed to achieve a balanced state.
Reinstall the wheels on the vehicle, ensuring they are torqued to manufacturer specifications (typically 76-80 ft-lbs for Toyota wheels).

4. Suspension Inspection

Lift the vehicle using a jack and secure it with jack stands.
Inspect struts and shocks for leaks, damage, or excessive wear.
Check control arms and bushings for cracks or degradation.
Replace any worn suspension components as needed.

5. Wheel Alignment

Use a wheel alignment machine to check alignment specs.
Adjust the camber, caster, and toe angles according to manufacturer specifications.
Document before and after measurements.

6. Test Drive

Conduct a test drive at various speeds to confirm that vibrations have been resolved.
Monitor for any residual issues that may arise.
