Solution

1. Preparation

Gather tools: jack, jack stands, tire pressure gauge, torque wrench, wheel balancer, alignment tools.
Ensure the vehicle is parked on a level surface and the parking brake is engaged.

2. Tire Inspection and Pressure Adjustment

Sub-steps:
1. Remove wheel covers if applicable.
2. Inspect tires for uneven wear, bulges, or damage.
3. Measure and adjust tire pressure to the manufacturer's specifications (typically found on the door jamb).
4. Rotate tires if uneven wear is present.

3. Wheel Balancing

Sub-steps:
1. Remove the wheels from the vehicle.
2. Mount each wheel on a wheel balancer and spin to check for imbalance.
3. Add weights as necessary to achieve balance.
4. Reinstall wheels and torque to specifications (typically 80-100 ft-lbs).

4. Suspension and Drivetrain Inspection

Sub-steps:
1. Lift the vehicle using a jack and secure it with jack stands.
2. Visually inspect control arms, bushings, and struts for damage or excessive wear.
3. Check CV joints and driveshaft for signs of wear or play.
4. Replace any worn or damaged components as necessary.

5. Wheel Alignment

Sub-steps:
1. Use an alignment machine to check and adjust the wheel alignment.
2. Adjust toe, camber, and caster settings to factory specifications.
3. Test drive to confirm that the vibration has been resolved.
