Solution

1. Preparation

Tools Required: Jack and jack stands, socket set, torque wrench, pry bar, and a diagnostic stethoscope.
Safety Warnings: Ensure the vehicle is on a flat surface and securely supported by jack stands before beginning work.

2. Remove Damaged Components

Sub-steps:
1. Loosen lug nuts and lift the vehicle using the jack.
2. Securely place jack stands under the vehicle.
3. Remove the wheel to access the suspension components.
4. Use the socket set to unbolt any damaged struts or shocks.
5. Remove any control arms or bushings that show deterioration.

3. Install New Components

Sub-steps:
1. Position new struts or shocks in place.
2. Hand-tighten the bolts to hold the components in position.
3. Use a torque wrench to tighten bolts to manufacturer specifications (typically around 40-60 ft-lbs for strut bolts, but check the service manual for exact specs).
4. Replace any bushings or control arms as necessary, ensuring all components are fitted correctly.

4. Reassemble and Test

Sub-steps:
1. Reinstall the wheel and hand-tighten the lug nuts.
2. Lower the vehicle back to the ground.
3. Torque the lug nuts to the manufacturer's specification (usually 76-83 ft-lbs for RAV4).
4. Test drive the vehicle to ensure the noise has been resolved.
