Solution

1. Preparation

Gather necessary tools and parts: tire pressure gauge, alignment machine, jack, jack stands, and torque wrench.
Ensure the vehicle is on a flat surface and parked safely.

2. Tire Pressure Adjustment

Sub-steps:
1. Use a tire pressure gauge to measure the current pressure of each tire.
2. Inflate or deflate tires to match the manufacturer's recommended pressure (found on the driver’s side door jamb).

3. Tire Rotation

Sub-steps:
1. Jack up the vehicle and secure it with jack stands.
2. Remove the tires in the order specified by the manufacturer (usually front to rear and vice versa).
3. Rotate tires to ensure even wear distribution.
4. Reinstall tires and torque lug nuts to the manufacturer's specifications.

4. Alignment Adjustment

Sub-steps:
1. Place the vehicle on an alignment rack.
2. Follow the manufacturer's specifications for adjusting camber, caster, and toe settings.
3. Make necessary adjustments until all angles are within the specified range.

5. Suspension Inspection and Repair

Sub-steps:
1. Inspect suspension components such as control arms, bushings, and struts for wear.
2. Replace any worn components as needed.
3. Recheck alignment after any suspension repairs.
