Solution

1. Preparation

Gather tools: jack and jack stands, tire pressure gauge, torque wrench, wheel balancer.
Ensure the vehicle is parked on a flat surface and the engine is off.

2. Tire Inspection

Check Tire Pressure
- Use a tire pressure gauge to check each tire's pressure.
- Inflate tires to the recommended PSI found in the owner's manual or on the driver’s door jamb.
Inspect Tires
- Visually examine each tire for any signs of damage, bulges, or uneven wear.
- Replace any damaged tires as necessary.

3. Wheel Balancing

Remove Wheels
- Loosen lug nuts with a socket wrench and lift the vehicle using a jack.
- Place jack stands under the vehicle for safety.
- Remove the wheels.
Balance Wheels
- Mount the wheels on a wheel balancer.
- Follow the machine's instructions to balance each wheel.
- Add weights as needed and re-check balance.

4. Suspension Inspection

Visual Check
- Inspect control arms, ball joints, struts, and bushings for any signs of wear or damage.
- Look for any leaking fluid from shocks or struts.
Replace Worn Components
- Replace any worn or damaged suspension components as necessary using appropriate torque specifications.

5. Wheel Alignment (if necessary)

Check Alignment
- Use an alignment machine to check toe, camber, and caster angles.
- Adjust alignment settings as per manufacturer specifications.

6. Reassemble and Test Drive

Reinstall the wheels, tightening lug nuts to specified torque.
Lower the vehicle and perform a test drive to confirm the vibration issue is resolved.
