Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface and engage the parking brake.
Wear safety glasses and gloves for protection.

2. Lift the Vehicle

Use a jack to elevate the vehicle and secure it with jack stands.
Ensure the vehicle is stable before performing any work underneath.

3. Inspect Suspension Components

Check the shock absorbers for leaks or damage.
Examine the strut mounts and bushings for wear or deterioration.
Inspect control arms and their bushings for cracks or excessive play.

4. Tighten or Replace Components

If any bolts are loose, tighten them to the manufacturer’s specifications (refer to service manual for torque values).
Replace any worn or damaged bushings, mounts, or shocks/struts as necessary.
- For replacing shocks/struts:
  - Remove the lower bolt using a socket wrench.
  - Remove the upper mount bolts from the top of the strut assembly.
  - Install the new strut in reverse order, ensuring proper torque specifications are met.

5. Reassemble and Lower the Vehicle

Double-check that all components are securely fastened.
Carefully lower the vehicle from the jack stands and remove the jack.
Test the vehicle to ensure the noise has been resolved.
