Solution

1. Preparation

Gather tools and materials: socket set, torque wrench, jack stands, and a stethoscope.
Ensure the vehicle is parked on a flat surface and the engine is off.

2. Lift the Vehicle

Use a jack to raise the front or rear of the Camry, depending on where the noise is suspected to originate.
Secure the vehicle on jack stands to ensure safety.

3. Inspect and Replace Components

Struts and Shocks:
- Check for oil leaks or damage. If found, remove the strut or shock using a socket set.
- Replace with new units, tightening bolts to manufacturer specifications (typically 50-65 ft-lbs).
Sway Bar Links and Bushings:
- Inspect for wear; replace if necessary. Remove the sway bar link by unscrewing the nuts with a socket set.
- Install new sway bar links and torque to the recommended specifications.
Control Arm Bushings:
- Look for cracked or worn bushings. If faulty, remove the control arm using a socket set and replace the bushings.
- Reinstall and torque to the manufacturer’s specifications.

4. Reassemble and Lower Vehicle

Re-check all bolts and connections for tightness.
Lower the vehicle back to the ground and remove jack stands.
