Solution

1. Preparation

Tools Required: Jack and jack stands, socket set, torque wrench, pry bar, and a suspension tool kit.
Lift the vehicle using a jack, and secure it on jack stands. Ensure the vehicle is stable before proceeding.

2. Inspect Suspension Components

Sub-steps:
1. Visually inspect the front and rear suspension components including control arms, struts, shocks, and sway bar links.
2. Use a pry bar to check for play in the bushings and joints. Replace any worn-out parts.

3. Tighten Suspension Bolts

Sub-steps:
1. Using a socket set, check the torque specifications for suspension components as per the manufacturer's manual.
2. Tighten any loose bolts to the recommended torque values.

4. Replace Worn Components

Sub-steps:
1. If any components (e.g., struts, shocks, sway bar links) are found to be worn, remove them using the socket set.
2. Install new components, ensuring they are secured properly and torqued to specifications.

5. Final Checks

Sub-steps:
1. Re-check all suspension bolts and bushings after installation.
2. Lower the vehicle and perform a bounce test again to confirm the noise is eliminated.
