Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is off.
Wear safety gloves and goggles for protection.

2. Tire Inspection and Replacement

Sub-steps:
1. Remove the hubcaps or wheel covers if applicable.
2. Loosen the lug nuts on the affected tires while the vehicle is on the ground.
3. Raise the vehicle using a jack and secure it with jack stands.
4. Remove the lug nuts and take off the wheels for inspection.
5. Measure tread depth using a tread depth gauge; replace tires if tread depth is below 2/32 inches.
6. Inspect tires for bulges, cuts, or foreign objects and replace if necessary.
7. Reinstall the wheels and torque the lug nuts to the manufacturer's specifications (typically 76 ft-lbs for Corolla).

3. Suspension and Alignment Adjustment

Sub-steps:
1. Examine shock absorbers and struts for fluid leaks or damage.
2. Check control arms, bushings, and sway bar links for wear.
3. If any components are worn, replace them accordingly.
4. Adjust the wheel alignment using an alignment machine to match the specifications provided by the manufacturer.

4. Traction Control System Check

Sub-steps:
1. Inspect ABS wheel speed sensors for dirt or damage.
2. Clean or replace any faulty sensors as needed.
3. Clear any error codes from the vehicle's computer system using an OBD-II scanner.
