Solution

1. Preparation

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

2. Raise the Vehicle

Use a jack to lift the front or rear (depending on where the noise is coming from) of the vehicle.
Secure the vehicle with jack stands to ensure safety while working underneath.

3. Inspect and Replace Components

A. Shock Absorbers/Struts

Sub-steps:
- Remove the wheel to access the suspension components.
- Unbolt the top and bottom mounts of the shock absorber or strut using the socket set.
- Remove the shock absorber/strut from the vehicle.
- Install the new shock absorber/strut by reversing the removal steps. Torque bolts to manufacturer specifications.

B. Sway Bar Links

Sub-steps:
- Inspect the sway bar links for wear or damage.
- If replacement is needed, unbolt the old sway bar links from the sway bar and control arm.
- Install new sway bar links, ensuring they are properly torqued.

4. Reassemble and Lower Vehicle

Reinstall the wheel and torque the lug nuts to the specified value.
Lower the vehicle from the jack stands and remove the jack.
