Solution

1. Preparation

Gather Tools: Ensure you have a jack, jack stands, lug wrench, tire pressure gauge, and wheel balancer.
Safety Precautions: Park the vehicle on a flat surface, engage the parking brake, and wear safety glasses.

2. Tire Inspection

Inspect Each Tire: Remove the hubcaps if necessary and visually inspect each tire for uneven wear, cuts, or bulges.
Check Tire Pressure: Use a tire pressure gauge to ensure all tires are inflated to the manufacturer’s specifications.

3. Wheel Balancing

Mount Tires on Balancer: Remove the wheels and mount them on a wheel balancer.
Adjust Weights: If the balancer indicates that wheels are out of balance, add or reposition wheel weights accordingly.

4. Wheel Alignment

Perform Alignment Check: Use an alignment machine to check if the wheels are properly aligned.
Adjust as Necessary: If misalignment is found, adjust the camber, toe, and caster as specified by the manufacturer.

5. Suspension Inspection

Visual Inspection: Check for signs of wear on suspension components such as control arms, struts, and bushings.
Replace Worn Parts: If any parts are found to be defective, replace them with OEM or quality aftermarket components.

6. Final Checks

Tighten Lug Nuts: After reassembling wheels, ensure all lug nuts are tightened to the manufacturer’s torque specifications (typically around 76 lb-ft for Toyota Corolla).
Test Drive: Take the vehicle for a test drive to confirm the shaking issue has been resolved.
