Solution

1. Preparation

Gather all necessary tools and parts.
Park the vehicle on a flat surface and engage the parking brake.
Disconnect the battery if working on electronic components.

2. Inspect and Replace Suspension Components

Inspect Struts/Shocks:
- Remove the wheel to access the strut assembly.
- Check for signs of oil leakage or damage on the struts/shocks.
- If damaged, proceed to replace the shocks/struts.
Replace Worn Bushings:
- Use a socket set to remove bolts securing the control arms.
- Replace any worn or cracked bushings with new ones.
- Torque bolts to manufacturer specifications.

3. Check and Tighten Loose Hardware

Inspect all suspension attachment points for loose bolts or nuts.
Use a torque wrench to tighten all fasteners to the specified torque values.

4. Inspect Exhaust System

Check the exhaust system for any loose hangers or clamps that may be causing noise.
Tighten or replace any loose components as necessary.

5. Test Drive

After repairs, perform a test drive over bumps to confirm that the noise has been resolved.
