Solution

1. Preparation

Gather the necessary tools and parts.
Ensure the vehicle is parked on a flat surface and the parking brake is engaged.
Gather tools such as a jack, jack stands, torque wrench, and alignment tools.

2. Tire Rotation

Sub-steps:
1. Loosen the lug nuts on all four tires while the vehicle is on the ground.
2. Use the jack to lift the vehicle and secure it with jack stands.
3. Remove the tires and rotate them according to the manufacturer's recommended pattern (e.g., front to back, side to side).
4. Reinstall the lug nuts and torque them to the manufacturer’s specifications (typically around 100-120 Nm).

3. Wheel Alignment

Sub-steps:
1. Take the vehicle to a professional alignment shop or use a laser alignment tool if available.
2. Adjust the camber, caster, and toe settings to match the manufacturer’s specifications.
3. Recheck alignment after making adjustments to ensure all angles are within acceptable limits.

4. Suspension Inspection and Repair

Sub-steps:
1. Inspect all suspension components for wear, including control arms, bushings, and struts.
2. Replace any worn components with OEM or quality aftermarket parts.
3. After repairs, recheck the alignment to confirm that it remains within specifications.

5. Final Inspection

Sub-steps:
1. Recheck tire pressure on all four tires and inflate as necessary.
2. Test drive the vehicle to ensure that it handles properly and that there are no vibrations or pulling to one side.
