Solution

1. Tire Inspection

Sub-steps:
1. Remove any hubcaps or wheel covers to access the tires.
2. Inspect each tire for bulges, cracks, or uneven wear patterns.
3. Measure tire tread depth using a tread depth gauge.

2. Tire Pressure Adjustment

Sub-steps:
1. Use a tire pressure gauge to check the pressure of each tire.
2. Inflate or deflate tires to reach the manufacturer’s recommended pressure.
3. Replace valve caps securely.

3. Wheel Alignment Check

Sub-steps:
1. Take the vehicle to a professional alignment shop.
2. Have the technician perform a 4-wheel alignment.
3. Adjust caster, camber, and toe settings as needed to manufacturer specifications.

4. Tire Rotation and Balancing

Sub-steps:
1. Lift the vehicle using a jack and secure with jack stands.
2. Remove the wheels and swap their positions (front to rear and vice versa).
3. Have the wheels balanced using a wheel balancer machine.

5. Drivetrain Inspection

Sub-steps:
1. Visually inspect the driveshaft and axles for signs of damage or wear.
2. Check for loose or damaged mounting brackets.
3. If necessary, replace any damaged components.

Tools Required:
