Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is on a flat, level surface.
Raise the vehicle using a jack and secure it with jack stands.

Tools Required:

Jack and jack stands
Tire pressure gauge
Tread depth gauge
Alignment machine

2. Tire Pressure Adjustment

Check and adjust the pressure of each tire to match the manufacturer's recommended specifications.
Recheck periodically to ensure tires maintain correct pressure.

3. Tire Rotation

Remove the tires from the vehicle using a lug wrench.
Rotate tires according to the recommended pattern (e.g., front to back, side to side) to promote even wear.
Reinstall tires and torque lug nuts to the manufacturer’s specifications.

4. Suspension Inspection and Repair

Inspect all suspension components for wear, including control arms, bushings, and struts.
Replace any worn components as necessary, ensuring that all parts meet OEM specifications.

5. Wheel Alignment

Use the alignment machine to perform a four-wheel alignment.
Adjust camber, caster, and toe settings to meet the manufacturer's specifications.
Test drive the vehicle to confirm alignment accuracy.
