Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface and engage the parking brake.
Disconnect the battery if working on electrical components.

2. Inspect Suspension Components

Use a jack and jack stands to lift the vehicle securely.
Remove the wheel on the side where the noise originates.
Visually inspect the struts, shocks, and control arms for signs of wear or damage.
Check the condition of bushings and mounts.

3. Replace Worn Components

If any components are found to be damaged:
- Struts/Shocks:
  - Remove the strut assembly using a socket set.
  - Replace with new struts or shocks, ensuring proper alignment of mounting holes.
  - Torque the mounting bolts to the manufacturer's specifications.
- Control Arms:
  - Remove the control arm by unbolting it from the chassis and the wheel hub.
