Solution

1. Preparation

Gather tools and materials: jack, jack stands, tire pressure gauge, torque wrench, and wheel balancing machine.
Park the vehicle on a flat, level surface and engage the parking brake.

2. Tire Inspection and Pressure Adjustment

Check the tire pressure using a tire pressure gauge. Inflate tires to the recommended pressure if they are low.
Examine each tire for visible damage or uneven wear patterns. Replace any damaged tires as needed.

3. Wheel Balancing

Remove the tires from the vehicle using a jack and jack stands.
Mount tires onto a wheel balancing machine.
Follow the machine's instructions to balance each tire. Add weights as necessary to achieve balance.
Reinstall balanced tires onto the vehicle, ensuring proper torque (typically 80-100 ft-lbs, check manufacturer specifications).

4. Alignment Check

After installing the tires, take the vehicle to a professional alignment shop.
Request a four-wheel alignment check and adjustments as necessary to ensure proper tracking.

5. Drivetrain Inspection

Inspect the driveshaft and axle for any signs of wear or damage.
Tighten any loose bolts or components. Replace any damaged parts as needed.
