Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a flat surface and engage the parking brake.
Place wheel chocks behind the rear tires.

2. Raise the Vehicle

Use a jack to lift the front or rear of the vehicle based on where the noise is coming from.
Secure the vehicle with jack stands.

3. Inspect and Tighten Components

Check all suspension bolts and nuts (such as control arm, strut, and sway bar link bolts) for tightness.
Use a torque wrench to tighten these components to manufacturer specifications.

4. Replace Worn Parts

If any components (shock absorbers, sway bar links, bushings) are worn:
1. Remove the affected part using a socket set.
2. Install the new part, ensuring proper alignment and torque specifications.
3. Repeat for all necessary components.

5. Reassemble and Lower Vehicle

Ensure all tools are removed from under the vehicle.
Lower the vehicle back to the ground carefully.
