Solution

1. Preparation

Tools Required: Jack, jack stands, wheel chocks, socket set, torque wrench, pry bar, and safety glasses.
Safety Warnings: Ensure the vehicle is on a flat surface and securely supported with jack stands before starting any work.

2. Remove Wheel

Loosen the lug nuts slightly while the vehicle is on the ground.
Raise the front of the vehicle using a jack and secure it with jack stands.
Remove the lug nuts completely and take off the wheel.

3. Inspect and Replace Components

Suspension Inspection:
- Check strut mounts and bushings visually for cracks or signs of deterioration.
- Use a pry bar to test the movement of control arms and bushings; replace if excessive movement is noted.
Wheel Bearing Replacement (if found defective):
1. Remove the brake caliper and rotor.
2. Disconnect the axle nut and remove the hub assembly.
3. Replace the wheel bearing using a bearing press.
4. Reassemble in reverse order, ensuring all components are torqued to manufacturer specifications.
Steering Component Replacement (if found defective):
- Replace tie rods or steering rack as necessary, following specific service manual procedures for your model.

4. Reassemble

Reinstall the wheel and hand-tighten the lug nuts.
Lower the vehicle and then torque the lug nuts to the manufacturer's specifications (typically around 76 ft-lbs for a Corolla).
Recheck all replaced components to ensure proper alignment and fit.
