Solution

1. Preparation

Gather tools and materials: alignment tool, torque wrench, jack stands, tire pressure gauge, and safety glasses.
Park the vehicle on a flat surface and ensure it is in the "Park" mode.
Disconnect the 12V battery to ensure safety when working on electronic components.

2. Inspect and Replace Worn Components

Inspect Suspension:
- Check control arms, tie rods, and bushings for wear.
- If any components are damaged, replace them as necessary.
Tools Required: Socket set, torque wrench.
Safety Warning: Always wear safety glasses when working under the vehicle.

3. Adjust Alignment

Camber Adjustment:
- Loosen the bolts on the upper control arms.
- Adjust the camber to the manufacturer’s specifications, typically between -0.5° and +0.5°.
Toe Adjustment:
- Loosen tie rod end lock nuts and adjust the toe to within the manufacturer’s specifications (usually 0.05° to 0.15°).
Caster Adjustment:
- If adjustable, follow the manufacturer’s specifications for caster angles, usually positive between 3° to 5°.
Tools Required: Alignment tool, torque wrench.
Safety Warning: Ensure the vehicle is securely supported on jack stands before working underneath.

4. Re-check Tire Pressure

Use a tire pressure gauge to ensure all tires are inflated according to the manufacturer's recommended PSI levels.

5. Finalize Alignment

Re-torque all suspension bolts to the manufacturer’s specifications.
Perform a final check using the alignment tool to ensure all angles are within specifications.
