Solution

1. Preparation

Gather tools and materials: jack, jack stands, wrench set, torque wrench, and flashlight.
Ensure the vehicle is parked on a flat surface with the parking brake engaged.

2. Lift the Vehicle

Use the jack to lift the front or rear of the vehicle, depending on where the noise is originating.
Secure the vehicle with jack stands for safety before working underneath.

Shocks/Struts: Check for leaks, dents, or physical damage. If damaged, replace with OEM or equivalent parts.
Control Arms: Inspect for bending or wear in the bushings. Replace if necessary.
Sway Bar Links: Check for play or damage. Replace if loose or broken.

4. Examine Exhaust System

Inspect exhaust hangers and brackets for looseness or damage. Tighten or replace as necessary.
Ensure no parts of the exhaust are making contact with suspension components.
