Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Wear safety glasses and gloves for protection.

2. Raise the Vehicle

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

3. Inspect and Replace Components

A. Inspect Sway Bar Links and Bushings

Remove the sway bar link bolts using a socket set.
If damaged, replace with new sway bar links and bushings.
Torque to manufacturer specifications (typically around 40 lb-ft).

B. Check and Replace Shocks/Struts

Remove the upper mounting bolts of the strut using a socket set.
Detach the strut from the knuckle.
Replace with a new shock/strut assembly.
Reassemble and torque bolts to manufacturer specifications (usually 15-20 lb-ft for upper bolts, 50-60 lb-ft for lower).

C. Tighten Loose Bolts

Inspect and tighten any loose bolts or hardware in the suspension system to manufacturer specifications.

4. Reassemble and Lower Vehicle

Reattach all components removed during inspection.
Lower the vehicle from jack stands and remove the jack.
