Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is on a level surface and securely lifted using jack stands.
Tools required: alignment tool, torque wrench, socket set, and wheel chocks.

2. Inspect Suspension Components

Sub-steps:
- Remove the front wheels using a socket set.
- Visually inspect control arms, tie rods, and bushings for wear or damage.
- Replace any damaged components before proceeding with alignment.

3. Adjust Alignment

Sub-steps:
- Use an alignment tool to measure camber, caster, and toe angles.
- Adjust the toe angle by loosening the tie rod lock nuts and turning the tie rod ends to achieve the correct specification (typically around 0° to 0.1° toe-in for the Corolla E140).
- Adjust the camber by adjusting the upper strut mounts, if applicable.
- Tighten all nuts and bolts to the manufacturer's torque specifications (check service manual for exact values).

4. Test Alignment

Sub-steps:
- Reinstall the front wheels and lower the vehicle.
- Perform a test drive to check for pulling or steering issues.
- Recheck alignment angles to ensure they remain within specifications.
