Solution

1. Preparation

Tools Required: Jack and jack stands, lug wrench, tire pressure gauge.
Ensure the vehicle is parked on a flat surface and turn off the engine.
Engage the parking brake for safety.

2. Tire Inspection

Sub-steps:
1. Use a tire pressure gauge to check each tire's pressure and inflate them to the recommended PSI as per the owner’s manual.
2. Visually inspect each tire for any bulges, punctures, or uneven wear patterns.
3. Rotate the tires if uneven wear is detected.

3. Wheel Balancing

Sub-steps:
1. Remove the wheel and tire assembly from the vehicle using a lug wrench.
2. Take the wheel to a tire balancing machine and balance it according to the manufacturer's specifications.
3. Reinstall the balanced wheel and torque the lug nuts to the manufacturer's specified torque value.

4. Suspension and Alignment Check

Sub-steps:
1. Inspect suspension components including tie rods, ball joints, and struts for wear or damage.
2. If any components are worn, replace them as necessary.
3. Use an alignment machine to check and adjust the wheel alignment to the manufacturer's specifications.
