Solution

1. Preparation

Gather tools: jack, jack stands, tire pressure gauge, torque wrench, and wheel balancing machine.
Ensure the vehicle is on a level surface and the engine is off.

2. Tire Inspection and Adjustment

Sub-steps:
1. Remove the wheel covers if applicable.
2. Use a tire pressure gauge to check each tire's pressure.
3. Inflate tires to the recommended PSI found in the owner’s manual.
4. Visually inspect tires for bulges, cuts, or uneven wear patterns.

3. Wheel Balancing

Sub-steps:
1. Remove the wheels from the vehicle using a lug wrench.
2. Place each wheel on the wheel balancing machine.
3. Follow the machine instructions to balance the wheels; add weights as needed.
4. Reinstall the balanced wheels and torque the lug nuts to the manufacturer’s specifications.

4. Suspension and Alignment Inspection

Sub-steps:
1. Lift the vehicle with a jack and secure it with jack stands.
2. Inspect control arms, bushings, and struts for any signs of wear or damage.
3. If any components are damaged, replace them before proceeding.
4. Use an alignment tool to check and adjust wheel alignment if necessary.

5. Drivetrain Inspection

Sub-steps:
1. Inspect the driveshaft for any visible damage or excessive play.
