Sub-steps:
1. Lift the vehicle using a jack and secure it with jack stands.
2. Remove the front or rear wheels, depending on the suspected area of noise.
3. Visually inspect the suspension components, looking for cracks, wear, or loose connections.
4. If any components (such as sway bar links, bushings, or struts) are damaged, remove them using the socket set.
5. Replace damaged components with OEM parts, ensuring that all bolts are torqued to the manufacturer's specifications.

3. Inspect Exhaust System

Tools Required: Socket set, exhaust hanger removal tool.
Sub-steps:
1. Check the exhaust system for any loose or damaged hangers that could cause noise.
2. Tighten any loose bolts or replace damaged hangers as necessary.
