Solution

1. Preparation

Tools Required: Jack and jack stands, socket set, torque wrench, crowbar, and safety gloves.
Ensure the vehicle is parked on a level surface and the parking brake is engaged.
Disconnect the battery if working on the suspension components.

2. Raise the Vehicle

Use a jack to lift the vehicle and secure it with jack stands.
Ensure the vehicle is stable before proceeding with the next steps.

3. Inspect and Replace Worn Components

Sub-steps:
- Remove the wheel to gain access to the suspension components.
- Use a crowbar to check for play in bushings; replace any that are cracked or deteriorated.
- Inspect struts and shocks for leaks; replace if necessary.
- Tighten any loose bolts and replace any worn sway bar links.

4. Reassemble and Lower the Vehicle

Sub-steps:
- Reinstall the wheel and hand-tighten the lug nuts.
- Lower the vehicle back to the ground.
- Torque the lug nuts to the manufacturer's specifications (typically 76 lb-ft for Camry).

5. Final Inspection

After repairs, perform a visual inspection to ensure all components are secure and in good condition.
Check that no tools are left on or under the vehicle.
