Solution

1. Preparation

Tools Required: Jack and jack stands, lug wrench, socket set, torque wrench, brake cleaner, stethoscope.
Park the vehicle on a level surface and engage the parking brake.
Disconnect the battery to prevent any electrical issues while working on the vehicle.

2. Inspect and Replace Brake Components

Sub-steps:
1. Remove the wheel using the lug wrench.
2. Inspect brake pads for wear; replace if they are thin or uneven.
3. Check brake rotors for scoring or warping; replace if necessary.
4. Clean the brake components with brake cleaner to remove dust and debris.
5. Apply anti-squeal grease on the back of the brake pads.
6. Reinstall the wheel, torque the lug nuts to the manufacturer's specifications (usually around 76 ft-lbs for Corolla).

3. Inspect and Replace Suspension Components

Sub-steps:
1. Visually inspect struts and shocks for leaks or damage.
2. Check bushings for signs of wear or cracking; replace if necessary.
3. If any components are worn, replace them using the appropriate tools.
4. Reassemble and ensure all components are properly tightened to specified torque values.

4. Examine Tires

Sub-steps:
1. Inspect tires for uneven wear patterns; rotate or replace as needed.
2. Check tire pressure and inflate to the recommended PSI.
3. If necessary, align the wheels using a professional alignment tool.
