Solution

1. Preparation

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

2. Raise the Vehicle

Use a jack to lift the front or rear of the vehicle, depending on where the noise is emanating from.
Secure the vehicle with jack stands to ensure safety.

3. Inspect and Replace Suspension Components

a. Check Shock Absorbers

Remove the bolts securing the shock absorber to the vehicle.
Remove the shock absorber from its mount.
Inspect for oil leaks or physical damage; replace if necessary.

b. Replace Worn Bushings

Locate the control arms and sway bar bushings.
Use a pry bar to remove the old bushings.
Install new bushings, ensuring they are properly seated.

c. Replace Sway Bar Links

Remove the old sway bar links by unbolting them from the sway bar and control arm.
Install new sway bar links, ensuring they are torqued to manufacturer specifications.

4. Reassemble and Lower Vehicle

Reattach all components securely, ensuring all bolts are torqued to the specified values.
Remove jack stands and lower the vehicle back to the ground.
