Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the parking brake is engaged.
Disconnect the battery to prevent any electrical issues.

2. Inspect Suspension Components

Visual Inspection:
- Check the struts, shocks, and springs for any visible damage or leaks.
- Inspect sway bar links and bushings for wear.
Tightening:
- Use a socket set to tighten any loose bolts on the suspension components.

3. Replace Worn Components (if necessary)

Remove Old Components:
- Use a jack to support the vehicle and remove the wheel for access.
- Use a socket set to unbolt and remove any damaged sway bar links or struts.
Install New Components:
- Position the new sway bar link or strut in place.
- Torque bolts to manufacturer specifications (typically 35-60 ft-lbs for sway bar links, check the service manual for specifics on struts).

4. Reassemble and Test

Reattach Wheel:
- Place the wheel back on and hand-tighten the lug nuts.
- Lower the vehicle and torque the lug nuts to the manufacturer's specifications (typically 76 ft-lbs for RAV4).
Test Drive:
- Conduct a test drive over bumps to ensure the clunking sound has been resolved.
