Solution

1. Preparation

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

2. Raise the Vehicle

Use a jack to lift the front or rear of the vehicle, depending on where the noise originates.
Secure the vehicle with jack stands to ensure safety while working underneath.

3. Inspect and Replace Components

Shock Absorbers/Struts:
- Remove the bolts securing the shock absorbers/struts to the upper and lower mounts.
- Replace with new shock absorbers or struts, ensuring the correct orientation.
- Torque the bolts to manufacturer specifications.
Sway Bar Links:
- Remove the sway bar links from the sway bar and control arm.
- Install new sway bar links, tightening to specification.
Bushings:
- If bushings are worn, use a pry bar to remove them from their mounts.
- Install new bushings, applying grease if necessary to facilitate installation.

4. Reassemble and Lower the Vehicle

Replace any components that were removed and ensure all bolts are torqued to the manufacturer’s specifications.
Carefully lower the vehicle back to the ground.
