Solution

1. Preparation

Gather necessary tools and parts.

Ensure all safety equipment is ready (jack stands, wheel chocks).

2. Lift the Vehicle

Using a hydraulic jack, lift the front or rear of the vehicle as needed.
Secure the vehicle with jack stands to prevent movement.

3. Inspect and Replace Components

Shocks/Struts:
- Remove the wheels using a socket set.
- Disconnect the strut from the vehicle by removing the bolts at the top and bottom using a torque wrench.
- Inspect for leaks or damage; replace if necessary.
- Install new struts or shocks, tightening the bolts to manufacturer specifications.
Bushings:
- Inspect control arm and sway bar bushings for wear.
- If damaged, remove the bolts securing the control arm or sway bar.
- Replace with new bushings and reassemble, ensuring all bolts are securely fastened.

4. Reassemble and Lower Vehicle

Reattach the wheels and torque the lug nuts to the specified value.
Carefully lower the vehicle back to the ground.

5. Final Checks

Recheck all bolts and connections for tightness.
Test drive the vehicle to ensure the noise has been resolved.
