Solution

1. Preparation

Gather necessary tools and parts.
Ensure vehicle is on a level surface and engage the parking brake.
Safety warning: Wear safety glasses and gloves.

2. Tire Balancing

Sub-steps:
1. Remove the wheel and tire assembly from the vehicle using a lug wrench.
2. Place the tire on a tire balancing machine and spin to check for imbalance.
3. Add weights as needed to balance the tire; ensure weights are secure.
4. Reinstall tire on the vehicle and torque lug nuts to the specified value (typically 76 ft-lbs for Corolla).

3. Tire Inspection and Replacement (if needed)

Sub-steps:
1. Inspect tires for damage, focusing on sidewalls and tread.
2. If damage is found, replace the tire with a new one of the same size and specifications.
3. Check tire pressure and inflate to the recommended psi (usually around 32 psi for Corolla).

4. Wheel Alignment

Sub-steps:
1. Take the vehicle to an alignment shop.
2. Perform a four-wheel alignment according to manufacturer specifications.
3. Adjust camber, caster, and toe settings as required.

5. Suspension Inspection and Repair

Sub-steps:
1. Inspect struts and shocks for leaks or physical damage.
2. Replace struts/shocks if any issues are found, using OEM parts for compatibility.
3. Check bushings for wear; replace if cracked or deteriorated.

6. Wheel Bearing Inspection

Sub-steps:
1. Raise the vehicle and remove the wheel.
2. Shake the hub to check for play; replace bearings if there is excessive movement.
3. Reassemble the hub and wheel, ensuring all components are secure.
