Solution

1. Preparation

Gather tools: socket set, torque wrench, jack, jack stands, pry bar, and a flashlight.
Ensure the vehicle is parked on a flat surface, and engage the parking brake.

2. Lift the Vehicle

Use a jack to lift the front or rear of the vehicle, depending on where the noise is coming from.
Secure the vehicle with jack stands to ensure safety during inspection.

3. Inspect and Replace Components

Shock Absorbers/Struts:
- Remove the mounting bolts using a socket set.
- Carefully extract the shock absorber/strut from the assembly.
- Inspect for leaks or damage. Replace if necessary.
- Install new shock absorbers/struts, tightening bolts to manufacturer specifications (typically 35-50 ft-lbs).
Sway Bar Links and Bushings:
- Locate the sway bar links and inspect for play or damage.
- Remove the bolts securing the sway bar links using a socket set.
- Replace any worn links with new components, ensuring all bolts are torqued to manufacturer specifications.

4. Reassemble and Lower Vehicle

Re-check all replaced components for security.
Lower the vehicle carefully and remove the jack stands.

5. Test Drive

Conduct a test drive over bumps to verify that the rattling noise has been resolved.
