Solution

1. Preparation

Gather tools: jack, jack stands, tire pressure gauge, torque wrench, tire balancing machine, alignment machine.
Ensure the vehicle is on a flat surface and the engine is turned off.
Safety Warning: Always use jack stands when the vehicle is lifted to prevent accidents.

2. Tire Pressure Check

Using a tire pressure gauge, check the pressure of each tire.
Inflate tires to the recommended pressure listed on the driver’s side door jamb if low.

3. Tire Inspection

Remove the wheels using a socket set to loosen the lug nuts.
Inspect each tire for visible damage or bulges.
Replace any damaged tires if necessary.

4. Wheel Balancing

Mount the tires on a tire balancing machine.
Follow the machine's instructions to balance each wheel; add weights as needed.
Reinstall the balanced wheels and torque the lug nuts to the manufacturer’s specifications (typically 80-100 ft-lbs, check specific values).

5. Wheel Alignment

Position the vehicle on an alignment rack.
Adjust the wheel alignment settings according to the manufacturer's specifications.
Verify that all settings are within acceptable ranges before securing adjustments.
