Solution

1. Preparation

Gather tools: jack, jack stands, tire pressure gauge, torque wrench, impact wrench.
Ensure the vehicle is on a flat, stable surface and the engine is off.

2. Tire Inspection

Sub-steps:
1. Remove the wheel covers or hubcaps if applicable.
2. Inspect all tires for visible damage (bulges, cracks, or uneven wear).
3. Measure tire pressure with a gauge; inflate tires to the manufacturer's recommended PSI.
4. Rotate tires if uneven wear is observed, ensuring they are in the correct position based on tread wear.

3. Wheel Balancing

Sub-steps:
1. Remove the wheel from the hub using an impact wrench.
2. Take the wheel to a professional tire shop for balancing, or use a wheel balancer if available.
3. Reinstall the wheel and torque lug nuts to the manufacturer’s specifications (usually around 70-80 ft-lbs for RAV4).

4. Suspension and Alignment Check

Sub-steps:
1. Visually inspect all suspension components (struts, shocks, control arms) for signs of wear or damage.
2. Replace any worn-out suspension parts as necessary.
3. For alignment, take the vehicle to a professional alignment shop to ensure it is within specifications.

5. Final Inspection

Sub-steps:
1. Recheck tire pressure after any adjustments.
2. Test drive the vehicle at high speeds to confirm that the shaking has been resolved.
