Solution

1. Preparation

Tools Required: Jack, jack stands, socket set, torque wrench, pry bar, and a rubber mallet.
Safety Warnings: Ensure the vehicle is on a level surface and the parking brake is engaged before lifting.

2. Raise and Support Vehicle

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

3. Inspect Suspension Components

Check the struts/shocks for signs of oil leakage. If leaking, they need to be replaced.
Use a pry bar to test the play in control arms and bushings. Replace any components that exhibit excessive movement.

4. Replace Worn Components

If the sway bar links or bushings are worn:
1. Remove the old sway bar link: Use a socket to remove bolts securing the link. If it's stuck, tap it with a rubber mallet.
2. Install the new sway bar link: Align it properly and hand-tighten bolts, then torque to the manufacturer’s specifications (typically around 40 Nm).
If struts or shocks are leaking:
1. Remove the strut assembly: Unbolt from the top mount and lower control arm.
2. Replace the strut: Install new strut and torque bolts to specifications (usually around 70 Nm for top mount and 50 Nm for lower).

5. Reassemble and Lower Vehicle

Reinstall any components that were removed during inspection and replacement.
Carefully lower the vehicle back to the ground and remove jack stands.
