Solution

1. Preparation

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

2. Tire Inspection

Remove the wheel covers if applicable.
Visually inspect each tire for bulges, cuts, or uneven tread wear.
Check that the lug nuts are properly torqued to the manufacturer's specifications (typically 80-100 ft-lbs).

3. Wheel Balancing

Mount the tires on a wheel balancer.
Spin each wheel to identify any imbalance.
Add weights as necessary to achieve balance, ensuring they are evenly distributed around the wheel.

4. Suspension Inspection

Lift the vehicle with a jack and secure it with jack stands.
Inspect control arms, bushings, and struts for any signs of wear or damage.
Replace any worn components as needed.

5. Wheel Alignment

Use an alignment tool to check the toe, camber, and caster angles.
Adjust the suspension components to align with the manufacturer's specifications.
Tighten all adjustment bolts and verify alignment settings.

6. Reassemble and Test Drive

Reinstall the wheels and lug nuts, ensuring proper torque.
Lower the vehicle and perform a test drive to check for vibrations at high speeds.
