Solution

1. Preparation

Gather tools: socket set, torque wrench, jack stands, and a creeper.
Ensure the vehicle is parked on a level surface and the engine is off.
Safety Warning: Disconnect the battery before working on electrical systems if applicable.

2. Raise the Vehicle

Use a jack to lift the front or rear of the vehicle, depending on where the noise is originating.
Place jack stands securely under the vehicle to support it.

3. Inspect and Replace Components

Suspension Inspection:
- Inspect struts and shocks for leaks or damage.
- If damaged, remove the strut assembly using a socket set, and replace it with a new unit, ensuring to torque the bolts to the manufacturer’s specifications.
Sway Bar Links and Bushings:
- Check the sway bar links for wear. If any are worn out, remove the old sway bar links and install new ones, tightening to manufacturer specifications.
- Inspect the sway bar bushings; if they are degraded, replace them as well.
Control Arm Bushings:
- If control arm bushings are worn, remove the control arm and replace the bushings. Properly torque the control arm bolts during reinstallation.

4. Reassemble and Lower Vehicle

Ensure all components are securely fastened.
Lower the vehicle off the jack stands and remove the jack.
